David Clarke Posted April 4, 2020 Share Posted April 4, 2020 Good evening guys. I have a 2009 Subaru Impreza wrx sti 330s 2.5L and I've been thinking about replacing the standard panel air filter with a K&N cone air filter, could anyone advise if this is a good or bad idea and if so is there something else I could do instead to upgrade the air intake?

ROSSCOSM Posted April 5, 2020 Share Posted April 5, 2020 Ask most subaru fanatics and they will tell you its pointless unless your going for “big” power amd it really needs mapped in. A good solution is to just throw in a better panel filter that firs the original air box like cosworth/ k&n ect 2 Quote Link to comment Share on other sites More sharing options...

ROSSCOSM Posted April 6, 2020 Share Posted April 6, 2020 Its a cheap alternative mate then if you go down bigger power route in future you can go cone filter. Quote Link to comment Share on other sites More sharing options...
