stay away from e3 spark plugs. they gave me a better gas millage for the first month and then it was downhil from there. gave me a miss in the third cylinder. and then were almost impossibal to get out. there only good in lawnmowers. best spark plug is the double plaium plugs stock ones from motorcraft. only way to get better gas milliage is get a freshair intake and k&n airfiliter. tht honestly helped out my truck. btw im running P255/70/16 semi agressve tires and im only getting 15 city and 17 highway on a good day. i have the a 4.0l 4x4 single cab with 4.10 gears what am i doing wrong. ( fresh tune up clean air filiter and oil change every 3000 miles with full synthic motor oil.
