Always happy with E3
WBJJ1984✓ Verified Purchase•October 16, 2023
Worked great on my 2005 F-150 fx4 5.4L. Better throttle response, smoother idling and quicker start ups. Now i don't have to about breaking plugs with the stronger design over stock. When i got my truck someone had already changed the motorcraft plugs to autolite plugs. But my truck felt sluggish like it was stopped up or now getting a good burn. So sea foamed the motor than put in the E3 plugs and was amazed with the more power i got. Plus the E3 have a 100,000 mile guarantee.
Perfect fit

They work have not seen any of the clams they have made but they work I got them because I don't like Champion and everything I read on the Champion plugs people had problems with them not firing same for me with Champion plugs but wanted to try the one piece design. I would recommend the Kroil for remove of old plugs I did a my truck and sisters car turn the plugs 1/8 to 1/4 turn spray in Kroil wait 15 to 20 minutes and they all came out didn't brake one off 16 plugs not one even had trouble coming out.

These are a good replacement for the two price plugs for the Ford's and they fire better than a standard replacement
These do not fit a 2009 ford... ...

These do fit a 2004-08 ford. They have a different sized nut at the top then the stock spark plug. I am very impressed with the performance after I got all the old spark plugs out.
