Hi, I'm thinking of fitting either a K+N panel filter or a cold air intake kit with a cone air filter on my 2002 bugeye wrx, the question is would I need to remap it after changing to either one of these, I would imagine I would need a remap more so on the cold air kit, any advise welcome.

 

Just put a decent panel filter in, Cosworth or similar

 

ANYTHING that alters the AFR on a Scoob needs the map checked.
