new air filter

[millsy13]

Hi I have an 05 STI and was wondering what options I have for a new air filter, I don't want an induction kit and have heard that you have to watch what type of filter you buy. Any recomendations or ones to avoid?

Avoid Induction Kits

Go for either the STI or I think the cotton green panel filers are the best option.

Yeh i bought a Green Filter with cleaning kit off a GB on Scoobynet, was just about £40 delivered..... very slight diff in induction noise....

It depends if you want to have piece of mind or not. I put a cold air induction system on my 05 STi and it was running fine (over fueling but very safe) - but in doing so didn't give any BHP increase only a very nice noise. I decided to have a Tek3 EcuTek remap done and the car is now fueling correctly and absolutely flies. I have a magnex cat back exhaust, k&n typhoon induction kit and the remap and the car is making 300bhp and 290ft.lbs of torque - and that is with all three cats still in place.

Sti has only 2 cats from what I remember Dave. Downpipe and the centre. The WRX throws the up-pipe cat into the mix.

agree with Jamie, green cotton or STI filter. i used to run the STI filter inmine with no problems.

If you ever go for induction kit then if you get the standard sized 76mm one it is a case of plug and play so to speak but if like me you get the 80mm then you will need a remap to rescale your MAF.

In all honesty i would get a remap just for peace of mind if i fitted an induction kit.........but that is just me!!!
