Review: OEM - 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.
Review: 100% Motorcraft parts - Ordered these for my 2016 F150 3.5 Ecoboost All the plugs gaps were a little different. I prefer .028 gap as required. I had a little hesitation when I gun the gas on my truck. Replacing the plugs fix that problem. Truck has power again. I also recommend a magnetic 5/9 socket. I put as required dielectric grease on the tip of the boots and Silicone lubricant on the rubber coil top sleeve to help future removals.
