i had my car rolling roaded and it was ok apart from the bloke said the air filter seemed very restrictive and i would get a couple extra bhp with a better one so i was wondering what make people recomend. the car is a c20xe

k&n cone.

Didnt they do a test in total vauxhall a while back and k&n were one of the worst?

Ive heard pipercross are good or green air filters, but cant say for sure what the best one is

What filter have you got fitted?

TBH i cant see any open type cone filter being different to any other, not noticeably anyway.

Are you going pvs, if so you can try mine out. its only a cheep carbon inclosed one but works very well. With just that and a system my x16xe made 113.5 bhp and 120lbs

ive used the green cotton cones, they give a decent noise and are smallish tbh.

filters dont give hp.

i did a dynorun with a open autostyle filter, and a run with nothing after the air ratio meter.. same outcome.

No but it can make it a smoother engine pulling away
