I just replaced my paper air filter with a K&N oil filter Sunday. Before I was averaging around 18 mpg and after the drop in K&N I am now averaging 20 mpg. Driving habits are still the same. Thought I would share my findings.

does anybody have the part number for the 18 inch Magnaflow muffler? i'm assuming it's the round muffler, but there are different lengths of the round muffler. Also for the 5.3, it's 3" in and 3" out correct?
