Hi all I have a wrx 93 import and want to change air filter to a cone one is it worth it. If it is I was thinking of buying the apexi one so what extra pipes ect will I need.

Not worth the potential MAF scale-altering issues.

IIRC, the OEM airbox/MAF assembly is capable of north of 350bhp anyway. Just stick a brand new OEM paper job in there (or a non-oiled freer-flowing panel filter, if you must)...

 

Cheers I have a apexi ecu too will I see any power gain from changing to an induction cheers for ur reply

 

In that case, it's okay... So long as you get a professional remap!

 

No point leave well alone.
