i have a s4 tII. and have a n/a s5 airbox. my maf doesnt seem to fit. is there a rubber peice that i am missing? i was thinking about using a rubber peice like from ic piping. im going to be using a k&n. i want something different when im looking in the engine bay.

how much boost can i run with the stock air box? anybody have a fmic with stock airbox? any pics out there?

thanx

 

S4 and S5 air boxes are designed for different AFM and not interchangeable

 

^^^^ what he said

 

whats the difference? just the inlet for the maf? or internals of the box as well?

 

any pics of these in comparison?
