Bit of a cross roads...
Fellas..
Now looking at purchasing a panel filter for my wrx as the next part to tick off on my 'modifying to do' list
Question, do I go cosworth or k&n...reading alot of conflicting threads on the net with pro's and cons for both i.e. k&n being an oil filter so not so great for engine etc etc and foam filters like the cosworth let particles into the engine etc
What is the best recommendation?
P.s. can someone remind me the spark plugs for modified impreza's....PF...something??

I put a cosworth filter in my 2001 wrx. Throttle response and it pulled so much better, you can hear induction noise a bit better too how ever it was just a cheap uni part one in from previous owner
That was on a standard car part of a routine service too. I got it really cheap though.
I had a k and n panel on a pervious car and made no difference what so ever and tbh the cleaning of it was a pain. I've read that the oil nature of these filters don't sit well with sensitive MAF sensors on imprezas, ive also read that genuine subaru filters are very good too

Personally, i'd go K&N or Green. You'll only really benefit from a filter change after a map and as mentioned before, NGK PFR7B and make sure the gaps are set properly.
