Henbrs Iridium Spark Plug High Performance Replacement PZH14F SP-515 For Ford F-150 F-250 F350 5.4L Pack of 8

Just recently installed these spark plugs. Read very good reviews on these plugs. Normally, I install Motorcraft spark plugs in my 2007 Ford F-150, but wanted to try these to see how many miles I could get on these plugs. I usually get between 45,000 to 50,000 miles on the Motorcraft plugs. Thank you. Don

So far so good considering my truck has almost two hundred thirty thousand miles on it and the original owner never bothered to change a spark plug one time so I was surprised the truck was even still running but after putting plugs and coils and all that good stuff like it should have been done a long time ago the plugs work great everything's back to the way it should be. Great price on good plugs and I'll be buying the same ones next time I have to replace spark plugs and now it won't be 230,000 miles when they replaced blew my mind the previous owner didn't change spark plugs ever!

That’s fine

these Plugs would Cost 5 Time more ,fit well too !

Look like o.e. seem to work well. Have not had a problem yet.

I usually buy motorcraft spark plugs but wanted to try these and so far so good.

04 F150 5.4 triton .Cured my misfire. Ran super smooth .Great build quality despite the price .welded casing so it should come out without breaking when its done

I replaced my plugs and connectors on my 2006 F150 5.4 runs great and getting 18 mpg on the highway.
