Review: Very Good Quality - The quality of the product is very good and worked well. Noticeable upon start...runs smoother and better response. The plugs that come with this kit indicate compatible for F150 3.5 EcoBoost. They are compatible but at a hotter heat range of 6 vs 12 for the OEM plugs. After some research I found that many suggest a heat range of 6 for the Eco Boost. They are iridium plugs ILT6RG8G and normally used on Jaguars and Land Rovers. No cross reference will indicate compatibility until you discover these are actually NGK 95605. Then you begin to see the references toward heat range 6 as preferred using these on the 3.5 ecoboost engine. So this seems to be the best deal at this price point.
