hi my rolling road result was abit less than i thought it would be , i have a 96wrx v-limited with a apexi induction kit and an hks superdragger exhaust with 2nd decat it ran 258bhp at the flywheel on a dastek rolling road would my results have been better with the standard airbox or not if so can they be fitted with the hard pipe from the apexi instead of the resonator box cheers j

 

anyone j

 

std airbox with uprated filter will flow more than enough for you.

you will have cooler intake temps (heatsoak)

and the airbox won't mess up maf readings.
