Single platinum or iridium tip will last longer

Motorcraft AWSF-42C was spec and tend to work best

Just run the motorcraft copper cores. The ignition on these trucks arent "hot" enough to make any good use of anything fancier then that.

You can run quadruple platnium 4 electrode magic dust whatever whatever, wont hurt nothing but your wallet.

The advantage to platinum or iridium is in longevity. If they're not hard to get to, then copper is just fine. If the job is a pain and you'd rather not repeat it for the rest of the truck's life, consider spending a few extra dollars.

Expensive ones. I have more trouble trying to save money with plugs then I care to admit to.

motor craft SP (486 or 419). run these for a long time.
