STi V8 Intake Manifold
Back In Stock!!!

The best solution for TGV Deletes for the 2002-2005 WRX EJ20 is the JDM Spec C manifold. Not only does this manifold look amazing, it deletes your TGV's thus improving performance (you will need some form of engine management to turn off the CEL)*. Airflow to the engine is improved ~20% and the stock top feed injectors and fuel rail is retained (compatible with aftermarket injectors / rails)
Included is the CNC machined Gruppe-S fuel rail adapter to allow this all to happen.
Sold Out



JDM STI TGV Deletes

For 04+ 2.5 Cars only.
Don't waste your time welding up your stock TGV housings (and testing for leaks). Go OEM!
Increase airflow by ~20% with the JDM OEM TGV deletes for a limited edition STI car. They are BRAND NEW. Get rid of the pesky stock TGV's with the JDM housings. They are bolt on parts* and compatible with the factory intake manifold. You will need a form of engine management, such as the Cobb AP to remove the check engine light. Pricing is for a pair.

Gruppe-S Equal Length Exhaust Manifold
Free Helix Up-Pipe

Constructed from T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. Dyno proven to make up to 8hp and 12 ft-lbs of torque. The design of the Gruppe-S equal length manifold increses boost response. Spool up time is decreased incresing boost pressure at lower RPM's. Due to the exhaust pulses now being paired together the lumpy boxer sound is lost instead a smoother sound is produced.

Gruppe-S Unequal Length Manifold
Ceramic Coated

The Gruppe-S manifold is a 4 to 1 unequal length manifold. It will retain your boxer rumble and features T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. The 4-1 collector is cast to ensure the smoothest possible low rates. This header is dyno proven to make power; it will not lose power or torque in 2.5L applications anywhere in the RPM range. 2.0L motors will lose some low-end and mid- range power to gain more high-end power and torque. The more modified your vehicle is, the more pronounced the gains from these headers will be. The outside coating eliminates heat loss from the exhaust gasses (as compared to stock headers). Because warmer air travels more quickly and expands more quickly, this helps to spool the turbo more quickly

STi Engine Mounts
Limited Quantities In Stock

The STI "Group-N" Engine Mounts are designed to reduce excessive motion of your motor during hard acceleration, deceleration, and cornering. This is done by increasing material stiffness over your stock engine mounts. By decreasing this type of motion, more energy is focused to the drivetrain rather than shifting the engine.
