My truck is running strong on these double platinum's I'm really pleased with the pick up I have now along with smoother start ups and acceleration. I no longer slow down going up hills, lol I think mileage has improved but, they have not been in long enough for me to really prove that.I can say," I got the power back."

Champion has designed a true one piece plug design that surpasses the original problematic two piece that often breaks. Highly recommend this plugs for all 5.4 Triton. Very Happy with purchase!

It’s one piece design and adjustable gap is better than OEM Motorcraft. I won’t have to worry about them coming apart in the head when removing. 👍 I own two of the three valve ford engines , I am sure glad to find these.

I was warned that ford engines hate the Champ plugs. But with the break off situation I had to try. 60,000 miles later still firing good. I am going to change them soon because I don't want to fight to get them out.

These are the HIGHEST quality plugs that you can buy for the 4.6l 3valve modular 8. The engine literally idles better, runs better, has better throttle response and FORscan checking of the OBD2 verifies this.
