I know on the Gen 2's a lot of people were saying their truck ran smoother/better on 1 step cooler plugs, especially if tuned.

Has anyone done this on the Gen 3? If so what plug?

I’ve got the NGK 6510’s installed in my Gen 1 EcoBoost Expedition; with tune and Full Race components. This is per recommendation from Elite Performance and Tune in Colorado.

When I go to the auto parts store to get these plugs I always have to explain myself… as much as I don’t feel the need to. I walk-in, and ask for the NGK 6510’s. Alway get asked what year, make, and model. Again, I ask for 6 of the plugs. Again, I get asked what vehicle. Then, I explain that it doesn’t pull up under my vehicle. Then, they want to know why I want them. Because, I want them. ‍SMH!!!
