Interesting... so I still haven't figured out if adding a performance intake/exhaust has the potential to increase MPG. I went from a 99 corolla to an '07 Nitro

BUT - MPG went from like 31 to 18.
It didn't matter how I drove the 5-speed Corolla. I got ~31 mixed MPG. The Nitro however it really matters how I drive it. I MIGHT be able to get 22 MPG with very conservative driving. Now, if I do decide to add a performance intake/exhaust with conservative driving may I see an increase in MPG? Even if it's 2+ MPG it would be worth it to me.
