Great Product
My vehicle was jerking under light acceleration at 40 + mph and the new ignition coil packs solved the problem! I replaced all 8 as it's cheaper in bulk.

Great value
Truck was bucking under light acceleration around 45-50 so bad coils replaced all 8 and so far no bucking and no engine lights. Great price considering 1 coil alone can range from $45 to $90. Will update on how long they last.

I have installed the ignitions coils and they are a perfect fit.
I have used your instructional videos whether I buy parts or not from 1a Auto. I really appreciate the videos and how instructive they are. Thanks for such an easy to use system of instruction and available parts to complete the job!

Finally fixed my truck!
I have been dealing with my 2005 F150 engine having a skip or miss for about 4 months. I thought it was my transmission but when I started reading about others having the same issue online, I saw where the ignition coil was the problem with most of the F150's. Most of the sets of 8 coils were $200+. I saw these at 1/3 the price of others and decided to try them. I watched 1A's "how to" video. My son and I installed them on Saturday morning in less than 1 hour and WOW!....no more hesitation in my engine! I have about 100 miles on these coils and it runs like new. 100% satisfied!

So far So good.
'06 F250 5.4L developed a bad hesitation under minimal load. Knew it was either plugs or coilpacks. went with the easier and option of CP as the plugs have a reputation of snapping off in the head. Considerably cheaper through 1A Auto than anywhere else. Problem solved and at a fraction of the price.
