Alright, so I popped for the K&N filter -- added an average of 47 miles to my tank of gas. I can now get about 360 miles on a tank before I get too nervous and fill it with about 16.5 gallons. I wanna make it to 400 miles a tank -- any suggestions?
Would a higher performance intake increase MPG? If so which make/model and where do you find them?
What about those gizmos that you hook up to your car's computer that adjusts timing of shifts, and calin that you can increase HP?
I already have synthetic oil runnung thorough my ES that I change every 7,000 miles.
