We installed these in our RV with the triton V 10 and instantly noticed an increase in power, we had changed the coils already with stock coils because of a misfire, but these increased mileage by nearly 20% from 7 to 8.5 even though that doesn’t seem like 1.5 mpg is much of a gain on a 2000 mile trip it saved over 50 gallons of fuel. Nearly 1 whole fill! Highly Recommended

Smoother idle and noticeably quicker rpmwhen I stomp on the gas. But not reliable. I really regret spending my upgrade dollars on these. They are unreliable and have had me on the side of the road on two separate occasions because of a horrible misfire caused by a failure of one of these coils. They continue to fail one at a time since they are out of warranty $60 each locally this is getting old. Thanks Accel, your products used to be worth buying. That has sure changed.

3 of the 8 brand new coils were dead on arrival . Tested the coils but putting an old coil back in its spot and it idled fine again. Didn’t need these coils just wanted to dress up the engine a bit with a yellow

Put the coils on my 4.6l 2valve f150. 2k miles now. Noticeable gas mileage about 2mpg, and my edge tuner reads a consistent 15ftlb of torque increase. Idle still sucks....

I installed these coils in my 01 F150. So far so good. The engine runs very smooth, better power and is getting better mileage. I have installed these coils in 2 other F150 pickups. One of them about a year ago and it is still running great. I would recommend them.
