As Advertised
It was as advertised. Legit Motorcraft plugs, meaning OEM durability. Gap was accurate on them, which in turn made it easier to install. Better performance and power. The old plugs I replaced had 80,000 miles on them.

Buy with confidence!
Best price I could find online. Great quality you’d expect from oem plugs. All plugs were within gap spec. 2hr diy worth the time to learn and money saved from not going to the dealership. Super fast shipping.

These were Motorcraft authentic plugs. Functioned great in my truck. Good value. Fit well. Gap was off on some, so had to adjust some of them.

Worked perfec
These are exact as OEM and are the correct product. Performance and functionality all match and fit perfectly. These are not fake knockoffs like I have seen with some other products.

Not as Described
DO NOT BUY. I ordered these and went to replace my spark plugs after not opening the package for a few weeks to find used spark plugs in my “new” packaging. Because I waited a few weeks to open I missed the return window and could not get my money back. Don’t waste your time or money with these.

Only use OEM
Excellent spark plug after my engine was running rough and I had a miss I was over 100,000 miles I replaced my spark plugs for these open plugs and now I can feel my engine run most of the time. I will only use these open plugs from here out.
