2008 STI/WRX AEM Intake $255!

36 HP and 35 TQ Gains



AEM is proud to introduce its new Cold Air Induction System for the 2008 Subaru Impreza WRX and WRX STI (part # 21-478WR). The largest power gains for the 21-478WR (tested on STI) are 36 horsepower at 5,300 RPM and 35 lbs/ft of torque at 5,300 RPM as measured on Harman Motive’s All-Wheel-Drive Mustang Dynamometer. The same kit tested on a WRX model generated 13 horsepower at 5,500 RPM and 14 lbs/ft of torque at 4,100 RPM on Harman Motive’s All-Wheel-Drive Mustang Dynamometer. Dyno results and a description of AEM’s dyno and temperature testing procedures, along with a list of applications, are available on the company’s website at AEM.
AEM Cold Air intakes are dyno-tested against the competition to deliver unsurpassed performance. Each system is tuned on the dyno to deliver maximum torque and horsepower, and monitor OBDII sensors, Mass Airflow sensor (MAF) signal voltage and fuel trims during this process to ensure that all readings are within OEM parameters, eliminating the chance of a throwing a check engine light.

All Cold Air intakes are constructed of CNC, mandrel-bent 6063 aluminum, and feature reinforced, TIG-welded brackets and fittings for maximum durability. AEM also includes a heavy-duty steel heatshield with a powdercoated black finish, a complete hardware kit and comprehensive installation instructions with every Cold Air intake system. The 21-478WR comes in a special wrinkle-red finish specifically for the Subaru Impreza models. In addition of the standard 6063-aluminum pipe, AEM includes a built-in air straightener for this application, which keeps CELs away and fuel trims in line with the factory.


All AEM intakes include AEM’s revolutionary DRYFLOW synthetic performance air filter; the first cleanable, reusable performance air filter that does not require oiling to filter and trap dirt and contaminants (more DRYFLOW key features can be found below).

DRYFLOW Air Filter Key Features:

·Will NOT void your vehicle’s warranty!
·No oil eliminates chance of under- or over-oiling, taking the guesswork out of servicing
·Filter element cleans in minutes and is Guaranteed for Life!
·Unique filter media is independently tested at up to 99.52% cumulative filtration efficiency to particles as small as one micron, based on ISO 5011:2000 FINE DUST performance testing. Visit AEM for independent filtration test results
·A mineral reinforced plastic interior cage increases structural rigidity—it’s virtually impossible to collapse!
·No mesh screen means a reduced chance of filter damage from bumps during installation or cleaning
·Pending CARB exemption

All AEM Cold Air intake systems carry a limited lifetime warranty and are either 50-state legal or pending, excluding “Off Road” only systems which are identified in AEM’s application guides. Some AEM products are legal in California only for racing vehicles, which may never be used upon a highway. AEM designs, manufactures and assembles its cold air intake systems in the U.S.A.

Valve springs are one of the most stressed components within the engine. The springs can cycle thousands of times per hour. When high performance camshafts, with their longer duration and higher lift, are installed the stress can be increased even further. Cosworth valve springs are designed to control the valve under these demanding conditions and are wound from high quality steel with chamfered ends to reduce wear on valve train components. Designed to be used with original retainers with no machining required. These are the perfect compliment to our range of high performance camshafts with increased seat pressure ensuring maximum performance and durability.



This ring pack comprises a tungsten coated stainless steel top ring with increased ring tension to reduce blowby at increased engine speed and combustion pressure. The ring pack is Cosworth specific and has been designed and validated for use in racing and road engines such as the Formula Atlantic and Caterham CSR260. Rings can only fit with Cosworth pistons. The pack includes a set of 4 top rings, 2nd rings and oil control rings.

High performance engines reject a substantial amount of heat through the oil system. Maintaining oil pressure along with an increase in actual volume will help dissipate heat and stabilize oil temperatures. Additionally, sustained High RPM use may cause oil starvation at the rod and main bearings. Increasing the oil volume will help to prevent bearing damage and engine failure. The NEW Cosworth High Volume Subaru EJ20/EJ25 series oil pump utilizes a completely new inner and outer 12mm rotor to increase volume by 20%. Suggested applications include drag, track day and race use. Each kit includes all required mounting hardware and seals.



The piston is one of the most important components within an engine. It can be subjected to directional change up to 285 times every second and must withstand acceleration forces up to 8500g. Cosworth high performance forged pistons are designed and engineered to withstand this type of punishment and still perform. All Cosworth forged pistons are manufactured using the same methods as our Formula One pistons and feature friction reducing skirt coating, ultra strong pins, polished tops and patented anti-detonation bands. Additionally, each application uses a unique forging to minimize weight and ensure the strongest possible piston design. • Proprietary Cosworth alloy • Popular sizes • Unique forging • Skirt coating • Polished top • Anti-detonation bands • High strength pin





To ensure engine reliability in all conditions, original connecting rods should be replaced with heavy duty specification parts. Complete set of four includes heavy duty SPS rod bolt.



Increased engine performance often means increased engine speed and load. Original factory crankshafts may not withstand the added stress resulting in catastrophic engine failure. Additionally, factory Subaru crankshaft rod journals are lubricated from only one main oil feed. Cosworth billet crankshafts feature full-flow oiling whereby each rod journal is lubricated from two main sources. This provides superior lubrication during sustained high rpm use preventing rod bearing failure. Cosworth Subaru crankshafts are manufactured entirely in house from EN40B steel in a light weight-high strength design with a unique Isotropic Superfinish.



Engine bearings are one of the most vital components within an engine and are often overlooked when considering high performance upgrades. Performance engineered, multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design, metallurgy and engineering to deliver what drivers expect from high performance Tri-Metal engine bearings.

With months of testing, developing, and designing, Agency Power has completed the best GT35R complete turbo kit for your Subaru WRX or STI vehicle. This turbo kit is a bolt on high horsepower solution to your 2.0L or 2.5L car. The AP big GT35R turbo kit is designed to maximize performance for street, drag, or the ultimate road racing needs.

The kit includes all T304 stainless steel piping that is TIG welded and thick flanges. Piping includes a new 3" downpipe that will fit to your aftermarket or factory exhaust, a new uppipe to work with the factory style headers, a wastegate dump pipe, and a new intake pipe with MAF mount for perfect readings. The Garrett GT35R turbo is a complete ball bearing turbine that has a .63a/r for fast spool up and includes an 84 trim wheel. The turbo is both oil and water cooled. Agency Power supplies the necessary steel braided Teflon lines and Rubber hoses need to fit the factory connections. We also include a Tial 38mm wastegate to control pressure for maximum boost needs. The intake functions with a reusable K&N cone air filter. A stamped bracket is included to keep the intake pipe firm in place. Silicone couplers are available in red to connect the necessary piping. The kit includes an intercooler adapter pipe which connects from the compressor of the turbo to the intercooler piping. We have tested the kit with the APS, TurboXS, Perrin, and OEM top and front mount intercoolers. Lastly all stainless steel hardware is included to bolt the turbo kit together keeping it hassle for free for the life of it on the car.

The Agency Power GT35R turbo kit is designed to make over 500 wheel horsepower on race gas and over 400 wheel horsepower on pump gas as tested on the STI. The WRX will produce less horsepower on the stock motor. All numbers vary depending on car modifications, tuning, and environment. This turbo is custom designed to spool up at around 4000rpm's to give the best horsepower response throughout the powerband. The turbo is capable or running 30psi and greater of boost, however we recommend many modifications to ensure the safety of the motor.

We recommend having the following parts: Front Mount Intercooler, ECU, Fuel Pump, Injectors, Fuel Rails, Catback Exhaust. Other recommended parts would be to upgrade your clutch, flywheel, shifter, radiator, and other related parts.


Agency Power GT35R Turbo Kit - $2890



Your Subaru WRX or STI needs more power. One way to do this is by adding a high quality header to your car. No other company manufacturer high quality, power producing, and cost effective parts like Agency Power. The all new Agency Power stainless steel header kit is now available for your 2002 and up Subaru WRX and STI. This header fits either the 2.0L or 2.5L engines. This header is made from 321 stainless steel and includes inch thick flanges. The headers have a special designed collector to give perfect flow into the uppipe providing faster turbo spool and increased horsepower. The header can work with the factory uppipe or is sold with the Agency Power stainless steel uppipe. Installing the header will not only gain you about 15 wheel horsepower, it will also change the tone of your Boxer engine to a deeper and more aggressive sound. It is recommended to change the gaskets when installing this header kit. For questions on fitment, installation, or the product, please contact a sales associate.

Continually analyzing ways to improve power on the Subaru Turbo vehicle can be challenging. Many Subaru owners want their turbo cars to spool up quicker and still deliver great horsepower and torque gains. With the new Agency Power equal length header this is absolutely possible. By implementing the equal length tubing and merged collector, Agency Power is able to improve your turbo spool up by 300rpm. When testing this on header on an upgraded turbo vehicle, we were able to see gains on a Mustang Dyno of up to 30ft/lbs of torque and 20 wheel horsepower. With quicker turbo spool, both 60ft and ¼ mile times were improved upon at the drag strip. Because of the free flowing design of this header, you will see gains across the entire RPM range as exhaust flow is vastly improved.

The construction of the equal length header features polished 321 stainless steel. The header has CNC machined ½ inch thick flanges and includes everything you need to bolt directly on to your Subaru turbo vehicle (see fitment notes below). Because of the equal length design, this will cause you to lose the distinct Subaru engine sound for a smoother exhaust note. The header fits all Subaru WRX, STI, Legacy GT, and Forester XT. Some modifications to the factory oil filter, oil pan, and/or oil cooler may be required depending on your year. Some years the header will bolt directly up with no issues.


Agency Power Equal Length Header for WRX/STi/LGT/FXT - $595



There is no other company that makes high quality, power producing, and purposeful products like Agency Power. With an amazing exhaust system, it only makes sense for Agency Power to offer their all new uppipe to Subaru WRX and STI owners. This uppipe is made from 321 high grade stainless steel. Completely polished, the uppipe uses 1/2 inch thick flanges for maximum strength connecting to your factory or Agency Power aftermarket header. The AP uppipe includes a new gasket and bolts to connect to the header. The top side of the uppipe connecting to the turbo includes new exhaust studs for a secure fit to the factory or aftermarket turbo. We recommend purchasing an OEM gasket when installation. The all TIG welded uppipe includes a bung for your factory or aftermarket EGT gauge.

The uppipe is designed to replace the catalytic converter in the WRX and increase air velocity in the STI which has no cat. By replacing the uppipe, you gain faster turbo spool, quicker throttle response, and a increase of almost 10 wheel horsepower. The Agency Power uppipe is designed to fit on all Subaru WRX and STI from 2002 and up. For questions on fitment, installation, or the product, please contact a sales associate.

Continually developing and enhancing the Subaru WRX and STI cars has been the goal of Agency Power. With a complete line up to make your Subaru the best in it competition, Agency Power has just released their all new Racing Downpipe. This downpipe fits all Subaru WRX or STI cars from 2002 and up. The downpipe is full stainless steel with a cast bell mouth upper section. The thich flanges ensure a tight and strong seal. The downpipe deletes both your catalytic converters and bolts to all factory style turbos. The downpipes precision welds and polished piping give the AP Racing Downpipe that cutting edge. Each downpipe includes a bung for an aftermarket air/fuel sensor as well as a bung for the factory O2 sensor.

When adding an Agency Power Racing Downpipe to your Subaru WRX or STI, you will gain more horsepower and overall performance. The downpipe allows for better flow of the turbine and wastegate gasses. Unlike the factor downpipe that blocks the wastegate gasses from being released in an efficient manner, the AP downpipe has a large bell mouth which allows for both to flow smoothly out and down the pipe. The 3 inch diameter piping is the perfect size for the turbo cars from stock hp to 500 whp. The bellmouth will also allow for a little boost increase since there is less restriction. Mate this downpipe up with your aftermarket catback exhaust or one of our Agency Power catbacks for an amazing sound and almost 25 wheel horsepower gain.

Turbo cars need more air flow to make more power. Not only is air flow important, but how that air gets into your cars motor is an essential factor. With vehicle computers becoming more and more advanced, precision engineered products are necessary to optimize performance. Focused on quality, function, and style, Agency Power has developed this intake kit for the new 2008 and up Subaru WRX or STI.

This intake kit is sold as a cold air setup. The kit features a CNC aluminum MAF sensor mount on our intake tube with built in fins to keep air flow laminar. The intake kit includes a 5ply AP silicone coupler with clamps for easy install. To keep the cool air separated from the engine heat, Agency Power has developed this heat shield which mounts to factory chassis locations from the front crash beam to the fender. The high flow K&N cone air filter securely clamps in place to the short ram or cold air extension tube. The heat shields are powder coated in a textured black finish and the intake tubes are done in wrinkle red to match the STI intake manifolds.

Tested on a Mustang all wheel drive dyno, the Agency Power intake kit was installed on a 2008 Subaru WRX Sedan. The kit gained approximately 10 horsepower and ft/lbs of torque. At the peak horsepower point of 5000 rpm’s, the intake kit made almost 20 wheel horsepower. The intake kit fits all 2008 and up Subaru WRX and STI vehicles.

Agency Power highly recommends tuning your factory ECU when using any intake system larger than stock. This will allow for the highest power gain and prevent any operating issues.

We all love carbon fiber. Its light, its looks great and when done right its strong!

How about pulling 16lbs of weight off of the highest point on your WRX!!!!

How about a Carbon Fiber roof that weighs 10 lbs!!!!!

The AMS Carbon Kevlar Roof Not only weighs in 16 lbs less than the standard Impreza WRX STI Roof, but it's just as strong.

AMS is constantly looking for ways to improve our shop cars. After weighing in the stock roof at a whopping 26 lbs we knew there was a lot of room for improvement. Strength is something we could not compromise. From our Record setting Drag car to our NASA TTU Champion Time attack car we had to make sure that the structural integrity was maintained.

It fits perfectly in place of your existing roof, factory headliner and all.
