Motorcraft copper plugs

[SilverSHO]

I have the AGSP32C plugs in my car right now. Will these work without any ill effects, at least until I get a set of the double platinum plugs?

They will work, for about 10k miles.

As pointed out to me by Mark Nunnally, the AGSP32C is longer (by approx. .050"). If you have a forced induction / Nitrous setup, this plug is preferred over the AGSP32PP double platinum.

Keep an eye on how well the plug wire boot seals over the end of the plug. If there's a noticeable gap, change them over to the PP as soon as possible.

Functionally, the copper plugs will burn out faster - as you approach 10,000 miles, you may notice a slight loss of power.

Cool. Well, I guess I'll just get a set of PP plugs and save the copper ones for when I win the lottery and stick on a supercharger
