Ive currently got an inner wing mounted induction kit on my 2002 WRX. I want to revert back to the standard airbox with uprated panel filter and was wondering if I need a remap aswell?

 

Hi Kev, I had a inner wing mounted induction kit fitted as well, but with the rain we get and some times flooding I reverted back to the origional airbox with K+N panel filter. I had mine remapped to be safe. The car has a very smooth idle now. Steve.

 

Aah yeah I remember yours going to Dyno. Just wondering if it is really necessary.
