Bought an old oilfield F250 and was due for a 3rd coil when I decided it would best to just do the rest instead of one at a time. Friend showed me this site & couldn't argue with the price. The effect was immediate, truck felt like an F150 at first. Light & responsive. Now that I've done a road trip & gas mileage has reset I've hit 14.3mpg when I never did higher than the 10's prior.
GREAT VALUE & VERY GOOD PARTS,TRUCK DRIVES WITH VERY GOOD POWER & IDLE IS SO SMOOTH I HAVE TO LOOK AT THE TACH SOMETIMES TO TELL IF IT IS STILL RUNNING.INSTALL TOOK ABOUT 1 HR,EASY JOB.EVEN MY WIFE NOTICED THE RUNNING DIFFERENCE + SHE HELPED ON THE INSTALL.HAPPY WIFE , HAPPY LIFE .
I have put 1000 miles on them so far and things are running great. This seemed to be the resolve to my misfire code.
Purchased the Ford performance 8 piece coil packs. I couldn't have gotten a better deal! Since the price was so affordable, I was able to pay the extra for next day shipping. The coil 0acks arrived by noon the next day! Once I installed them myself, my truck runs like it's alive again. I'm definitely satisfied with the buying experience and fast shipping. The coils look high quality. Only thing is how long will they last, only time will tell. Thanks 1A auto!
Damn!!! I was skeptical at first for the cost but these woke up my 6.2 H Davison, start it and the truck twisted and and when put into reverse the torque twisted the truck and then in drive same thing. It wasnt like a monster twist but could feel it like never BEFORE these are an absolute must if youre looking for more POWER
Truck runs so much better
