Probably not alot. It may help a little on the higher rpms, but how much, I haven't seen any dyno test to prove anything.
Your butt-dyno will notice an decrease in wallet size though!! That's guaranteed!!
That's what i was wondering. Anyone done a dyno to show what the actual gain is? I had a 2000 Trans Am and when i switched from a stock airbox to an aftermarket, it made a huge difference in power and throttle response.
