That's alot of $ for some plugs.

 

There only purpose is for forced induction. Unless you have a turbo or a supercharger I really see no reason to buy them. A waste of money IMO.

 

I agree. Without FI i couldnt see the reason to buy those.

 

They would also be good if your spraying but would only hurt you if your stock.

 

GTs run PZT-1s as far as I know, which are already the colder service plug recommended for the 5.4 3V. I agree with the others, unless you're running forced induction or spray, you probably won't see any benefits over PZT-1s or 2s.

 

Yeah, those are the recommend plugs with a Wipple.

 

What is a good set of plugs for a stock f-150 with an evolution tuner?

 

The stock plugs aren't much cheaper

 

Hate to here that

any real good alternatives?

 

Good thing my first SP change was on a TSB.

 

The Autolite HTO are the same as the Ford Racing 0. Whipple told me either one would work just as well. Autolites run about $80 for a set.

 

The factory ones.

 

Im cool with that. Just testing the waters to see if anything was better out there.

 

Do the replacement factory plugs still run the risk of corrosion and breakage in the head?
