hi everyone. I have been checking and recording my mileage for the past month and i do not like the results. I have been averaging 237 miles to a tank of gas (16.94 including filler tube) which equals 14.8 mpg. which is mix between highway and city driving. I was wondering if the cone air filter could be making a difference. The car runs perfect. not even a sputter. Even at 90 on the highway it drives perfectly straight. I have always used mid grade in the car since i bought it 5 years ago. The exhaust burns clean. I have done fuel injection service, seafoam, completely cleaned the TB, new TPS, IAC, plugs, wires, coil packs. You name it it is new lol. Thanks for all of the insight. I do love the sound the air intake makes. And i do feel more power on takeoff with it.
