As above I have a Roger Clark induction kit on my STI Version 5. Now I bought the kit used and is looking a little old. I'm running a Simtek so no MAF would it be worth while buying the K&N cleaner kit or just replace the Filter? If so can anyone tell me what filter I need to replace it with. My plan is to run 380bhp approx.

Cheers

 

have a word with mattyb1983 on here he just got a new filter and was really cheap and k & n and they made it the size he wanted
