I have been thinking of ways in which to increase the gas mileage on my '01 Alero 2.2L....
I have seen quite a few CAI for the V6 but nothing for the 4 cylinder... Is this because it doesn't do much good to put a CAI in a 2.2L engine? Has anyone tried this and gotten better mileage? Also wondering if anyone has tried "The Turbinator" air intake insert? Did it help your HP/Mileage? Thanks in advance!
