Both as good as one an other, I went K&N for the little sticker you put on the air box to stop the mechanic throwing it away at service time

according to this months issue of jap performance car do luck gave 13bhp kn and green both gave about 10bhp on a rolling roaded 03sti

I saw this as well. It's also a lot cheaper.

Blimey 10bhp from a panel filter?? I'm too used to na cars, just stuck a k+n on my wrx but not had the chance to have drive in it yet.

There are a couple of threads around already about that "review". Well worth a read for anyone thinking of buying a filter on the basis of it.

I would say k&n personally , only because I have been using them for over 20 yrs, on at least 20 different cars( gti's,gte's, cosworths, etc),and can honestly say I have never had a problem with them. I have read that some people say that they are are over oiled,which can lead to maf failure, but I have bought 3 in the last 4 years for my various subaru's and not had any such issues.

I've happily used and re-used a Green cotton one for the past 6 years.

cosworth. Decent gains and not oiled.

bhp Gain isnt the only thing to consider, filtration is just as important

k&n for me but only because i have used them on my other cars, to be honest either is better than the paper element filters

One of the jap mags this month have a review of all the best air filters!! Green I think was second and gave an extra 10 bhp over standard. Pipercross if I remember was number 1 giving an extra 12.5 bhp

+ 1 for K&N.

That sounds like the same review Scoobydude87 referred to in #4. I wouldn't personally risk the "winner", even if it gave an extra 2.5bhp than the K&N I currently run (and it probably doesn't).

piperx gave 8bhp, do luck foam gave 12bhp but it doesnt state how well it actually filters
