Hey all,

Newbie squid to forum but long term Ford's owner (oldest is '47 2N). 1999 F-250 5.4L EFI w/96K. Wanting to change plugs before heading on vacation, pulling 28' TT. Have read details about alum heads vomiting plugs so I will be very careful. Question is, which plug is best? Have read that Motorcraft Platnimun was installed new but cannot seem to find them. Figured you'se guys and gals could give me some "sage" advice.

As always, Safety & blue skies,

DJ

I have never been a fan of platnium plugs because platnium isnt a great conductor of electricity. Autolite Coppers have worked out well for me.
