They work great and the price was very good. They dropped my gas mileage by 5 miles per gallon. I put them in a few months ago and haven't had any trouble. The Gap was very precise and no more misfire.

Just installed these on my 5.0 F150 at 100K, only put about 500 miles on them but all is good so far. At this point I would have no issue using them again.

Nice set of spark plugs, look same as OEM. FAST SERVICE THX.

So far so good!! Better idling and acceleration. Even got rid of a pesky CEL .Now we see how many miles before they fail????Inquiring minds want to know

Very pleased with these brand of plugs

Super quality cheap and good has 6 months installed and no problems at all

They work

I love this product because the original equipment in the truck was already past it's life expectancy.So I had issues with my truck where several cylinders were carbonized and so I added a bunch of additives to the fuel and the oil and did several oil changes while these spark plugs endured. All of these chemicals I added to the truck one way or another and after a thousand miles they're still holding up really well and my truck is not misfiring or anything like that. And they're burning everything I add to the fuel and oil.I'll buy this product over and over again.Great Product at a Great Price.
