Intake / Exhaust for better mileage
Will standard K&N intakes work as good as a cold air setup to improve gas mileage?
RE: the exhaust....
I will purchase one for the same reason, to help a tad with mileage (God I love it when I have good excuses to buy something!)
What is exhaust flows well but isn't that loud? I've come to really like the quieter cabin.
Will doing a cat back only help with the gas mileage?
