Spark Plug Gap

[greenpony02]

What gap should I use for my plugs. I know Ford reccomends something like .052-.056 for platinum plugs but what about copper? I've read something like .030, is this true? Any input would be great.

Platinum plugs come pre gapped for your car because if you try to gap them, they will break off. As for copper plugs, my application requires .035, but I don't know about N/A vehicle...

Anybody know for N/A applications?

Go with .055" Power adder motors require smaller gaps than N/A. Also, their is no difference for gaps in plugs regardless of what their composition is.

Always check the gap on all plugs. You can gap platinum plugs, and should.

For NA applications same gap no matter what type of plug.
I run mine at .054. Anywhere in the recomended range is fine.

Last time I changed mine I believe I gapped them at .045
