i have recently purchased an 2001 F150 with a 5.4L engine. i am goin to do a some tune up and upgrades to the truck and was starting with a few things like the spark plugs. i have an 87 5.0L mustang and have always ran the bosch platinum 2s and i believe that i am only supposed to run either motorcraft for autolite in the modular engines. my question is what is the best performance spark plug i can get or do i just stick with the motorcraft. i personally have never liked the autolite just bc a lot of the times i have changed spark plugs in the fords and i pull autolite out they look way worse than i have ever seen motorcraft. they just seem cheap to me. any info would help. thanks to all.
