I just went through this last night. Save yourself the trouble. The OD of the K&N filter is TOO big.

Anyone know about the Amsoil replacement #EaAU3570?? I just ordered mine the other day and now I am a bit worried.

I am looking into it right now and will post up if I find anything.

**UPDATE The Amsoil filter is a direct replacement for the K&N filter, so apparently it wont fit an 06/07 either. The OD is the same for the Amsoil and K&N filter

What are some more details it in not fitting? Just couldnt squeeze it in here?

Edit: I may have found a solution, but I can not confirm yet. I may try to install my APS CAI this weekend with the old K&N filter to see if I can get it to fit since the Amsoil filter I ordered is the same size. I am going to keep looking and I will post up again if I find a def solution or get it to fit this weekend.

In the mean time.. I found this so far

I assume they are referring to this bracket below. (in the above threads)

Is there another K&N filter that might work instead on the 06/07?

FIRST OFF. I deleted a couple posts that had nothing to do with adding a NON-OE filter to the APS CAI.

Ok.

As you pointed out, the OE APS CAI filter already has a tough time fitting within the fender. Now imagine another 1" in diameter (however much bigger the K&N is.

Here is where you will have problems:



The tube you are referencing is a bit misleading. Once you get into the install you will see that the firewall (?) with the arrow will get in the way. Also, the infamous bracket will be in the way.

[fourseasonsandles]

Hmm? Hammer?

[fourseasonsandles]

New filter came today. This doesnt look promising. The Amsoil filter looks to be bigger than the one that came with the intake. Im going to try and install it this weekend and see what happens.



Also my own rejuvenation of a used APS

[sirwilliam]

I found after removing my APS CAI today (do to the wife not liking the intake sound <WHOOOSH!>) that the bumper clips hit the K&N filter on mine as well. The K&N filter mesh was dented in at the top of 2-3 fins but won't affect flow. It is close to the inside fender wall but doesn't touch or rub.

Also, I noticed after putting the stock airbox back on that I lost a noticeable amount of power (not a huge amount but definitely noticeable) and w/o the snorkus in, the stock airbox isn't much quieter than the APS. I decided to just repaint the APS (black or WRB) and somehow convince my wife to let me keep it...regardless of the noise.

Interesting. I have a few ideas for this weekend to try and get mine to fit. But I am sure it is going to be tight.

You know, just for the hell of it I was thinking about to keep the engine bay rather stock looking. I wondered if you could cut the stock air box so that the APS CAI would run through the empty box. Paint your APS black and no one would know the difference unless they were really paying attention to detail. After thinking about it a bit, i realized that it wouldnt work with the MAF, but I still thought it would be neat.

It would take a lot of work that I am too lazy to do and would destroy your stock airbox so you couldn't swap back to it or sell it. I think I will just go w/ painting the intake FYI, in case you didn't realize, I have an '08 FSXT, not an STI...so fitment is slightly different but not much.

anyone know a filter replacement that does fit on '06 ?? since the k&n is to big OD.

I was thinking this might work, it is thinner then the stock filter.
