I'll know pretty soon!!!! CP-e shipping this monay!
But from past experience with other cars i've owned... You'll only really notice a difference if you race it more. The new "sound"... the increased performance... and the "idea" that you modded your car usually leads to harder and faster driving... which ownz everyones gas milage. But if you baby it around town or on the freeway I think you'll see about the same...
Then again it sounds like you're replacing the stock filter with a different brand? Rather than changing the intake? If thats the case... You should see no change at all...
