Copper Plugs

Tom, in another section you mentioned the use of copper plugs in heavily modded or F/I applications. What would you define as heavy modded? I currently run the stock Motorcraft plugs, still N/A and have pretty much of all the bolt on's. Soon to be installing the FR head milled .040 and FR2 cams and a trip to the dyno. Is it time for the copper plugs as well? Know part number on the copper plugs off hand?

Thanks

You can use the AZFS22C at any time you just have to change them more often so in not so heavy modded cars to keep from changing them often (2 maybe 3 times a year) use the Plat they will last years before having to change them

they are a colder plug so they help prevent detonation.
