Great Product Champion where Ford failed to fix our sparkplug issue.
I bought these plugs when My Lincoln Mark Lt was misfiring. These plugs in my opinion are way better than the motorcraft plugs. Plus the champion sparkplug is nearly twice the thickness than our motorcraft original plugs. I highly recommend this product. I never had a problem with these plugs in two years of use. We all know about the 5.4L 3 valve engine sparkplug breaking off in the cylinder head. Well this is our solution to ford's mess up. Yeah champion sparkplug is supposed to be for Chrysler products but seems they address our issues perfectly. Guys I recommend this product. They cost a bit more but they don't break off in the head when it is time to change them.Read full review

Perfect for Roush Supercharged setups.
When speaking with Roush Techs on the phone they informed me that they had not tested 'any' other spark plug for their SC systems. In my testing no other spark plug gives the same power or throttle response. I've tested the Ford Racing & Accell equivalents. Wild.Read full review

Have sparkplugs, but have not had time to install, they look good....
Have not installed the sparkplugs yet, so unable to state if they work as expected, they look nice and I feel they will do the job, just have not had the time to put the sparkplugs in the engine, they look as described, shipping was fast....Read full review

Perfect fit for 2007 sport trac
I have the 07 sport trac with the 4.6 v8 and changing to these plugs increased my mpg to 18 from 16.5. I also did boots and springs but not coils. Runs alot smoother, better mpg. Exactly what I was looking for.Read full review

Best 3v spark plugs!
In my opinion these plugs are the best option for not turbo charged high thread 3v 4.6L and 5.4L ford trucks and cars.
