E3 Spark Plugs
I have a 95 F-250 with a 5.8L V8 (351 Windsor) and I am thinking of putting E3 plugs in it. Has anyone here tried them with a truck like this and if so what do you think of them?

Just use the regular motorcraft plugs. If the E3s were so much better than they'd be in the from the factory. Electricity follows the closest path to ground that has the least resistance. Those plugs aren't any better than stock.

Only time i dont use stock plugs is if the engine is going to be boosted or sprayed... In my case I am a HUGE fan of NGK plugs... I run two steps colder in my Mustang for the nitrous hits... But for my truck (460) i put in Motorcraft copper cores.. BTW Copper Cores seem to burn hotter in my experince than any of these crappy irdium things...
