Man, I changed the fuel filter in both my cars and I was really suprised at the better mpg i'm getting now. my wife's car was plugged up worse than the stang she's getting like 7 mpg better now. i'm getting like 2-3. if you have over 35k miles on your car i would defintely recommend it.
my cars got 178000 miles it still flows haha i also have the oem cap rotor and wires :rollinglaugh: she runs like a champ though and my miliage aint bad at all so i see no reason to change... im not a mpg counter though glad to hear your saving gas O0
