hmm i can tell you to test it urself..
besicly.. you at night.. find a quiet plcae. *less car, ask one of ur friend follow you..
and.. do some test drive..
1st you drive that stretch.. floor it.. anyway.. just drive! then.. stop..
2nd remove your current air filter and... drive + floor it..

what diffrences you feel... and.. changing better air-flow filter = somewhere in between with stock air filter to no air filter at all...

just tell it.. and tell me you like it or not.. lol
