Hi, your 4k tow running package reduce the 1-2 miles + tire + lift kit + 89 gas = 3-5 mi/gal. I have a Lariat AWD with 91-92 gas... And my performance is around 22-23 mi/gal city-hw.... and 28-30 mi/gal only HW...of course my truck is STOCK (no mods)... Please try a performance chip. FORD motors...
Hi, This HOOD SCOOP; do you have to remove part of the hood (drilling or cutting), Is this a functional air cooling accessory?. Or it is just for a better appearance. : )
