hi guys, i here from a few people on here about the awsome noise these make,the only noise i here from mine is the rc dumpvalve through it when i change gear etc, no induction roar as such,is this normal?93wrx.
cheers, Dug.

 

put the standard airbox back on, you'll then realise how noisey the blitz is.

I changed to a HKS induction from standard and there is a lot more suction noise

 

have to say that the K+N 57i fairly sucks the air in as well. nice big whoooooooosh as the car comes on boost. getting used to it now.

cheers

big sinky
