Review: The Best For Ford - My 2015 F150 3.5 ecoboost had a misfire and I knew the time was here for new plugs. These are the OEM plugs Ford recommends. I always check gaps before installing, these were all on point coming out of the box! Easy to install the 6 and boom, my truck has been running problem free ever since. OEM quality, priced right, truck performs like royalty again.
Review: Great plugs for the cost - Got to replace the 6 plugs in my 2013 Ford F150 XLT and these have been holding up strong for the last 1/2 year w/o any issues. Very happy for the cost and quality.

### ⭐⭐⭐⭐⭐ OEM
*by D***Y on July 22, 2023*

I like to use oem equipment for my vehicle when the price is within reason. These fit the bill! These are the exact fit and and newest. version for my 3.5 eco boost engine. The price is better than the local auto parts stores and the newer style of plugs no longer need anti seize for installation. Recommended torque values are on the side of each package and the plugs come pre-gapped and are not adjustable, so you just remove old ones and install new ones. They also have a plastic sleeve that protects the gap during shipment.
