Do the aftermarket air cleaner mods do any good to actually improve milage or do they just make the engine look a bit different?

If you want max MPG, you need to run narrow street tires and near max pressure and no lift. Any changes you make to bigger and more aggressive tires and lift will hit you in lost MPG and no magic airfilter is going to make it up. Stock filter are pretty good and the engine is tuned pretty well intake and exhaust from factory though many seem to think otherwise. How you use your foot in the throttle is a big factor too.

he can help you to maximize your power/mileage. If you get a "hot" tune, you may have to burn super unleaded, but can get 3 mpg better, and since all gas is high right now, the difference between a $45 fill up and a $50 fill up is pretty negligable. I bought one more to correct for different size tires and to get better shifts (remove part of the torque management). Jesse is by far the least expensive progammer out there.
