Save me over 50% of what I would have paid for the same OEM spark plugs at a retail store! Checked the gap, they were true, and my truck has never ran better! Thank you!

When I first installed these spark plugs, I noticed the difference in power right away. However, because there are two electrodes developing spark, they will carbonize twice as fast.

I replaced the plugs on my 2016 F150 along with the boots and they worked out great and definetly time to change mine at 80k miles (see pic to see old vs new)

Bought these a few times and they seem to work ok! I have a 2016 F150 3.5L EcoBoost. I find that these Trucks after 100,000 miles need the plugs changes every 20,000 after that.

Was very surprised to see that the lot I got was all gapped perfectly at 0.3 from factory. They appear to be genuine and so far running well in the 2013 F150.

Saved a lot of money from buying at the local auto parts store. Exactly what I took out of my 3.5 Ecoboost. Gap was set correctly on all plugs.

Compre estas para el 5.0 (motorcraft CYFS12Y).Pero el gap o abertura que estas traen es de .03 pulgadas. Entonces las bujias son para el ecoboost 3.5No pude conseguir las motorcraft CYFS12Y aqui. Entonces tuve que aperturarlas un poco mas a .049" segun especificaciones para el motor 5.0, segun indica el manual.

These are oem Motorcraft plugs. I wasn't quite sure as they had Japan stamped on them. Doing some investigation these plugs are made by NGK (Japan) for Ford with their specifications and packaged as Motorcraft. The porcelain light- blue printing is correct as I have the original plugs that was used from the factory, this is the area that counterfeit plugs are not the same and the packaging is the updated correct all red printed package the counterfeit packaging is different. As a side thought an indium plug will give a + 25% service life compared to a platinum tipped plug. I'm satisfied with these plugs and at a good price compared to a Ford dealership.
