I've heard they just wear out faster....

They do wear faster, but copper is a much better conductor of electricity.
And, at under $2 a plug...who cares about how long they last? []

new ford p/n is SP463

what gap are you running your plugs at? I think spec is .042-.046 but are you and can you get away with gapping them further since its a better conductor?

 

[SVTbedson]

thanks for all the help guys. and about gaping idk but i would like to

The more the gap the better performance , if you can gap them at .060 and it does not misfire then do it

Factory spec is .051.
Just swapped mine out for the first time, and set them at .060:
