Thread: spark plugs for minor mods

How about the AC delco 41-932. They are copper like the autolites and 1 heat range colder.

Not supercharged, but AL605s have been doing great in my car so far.

Well I haven't heard any personal experiences with those plugs, but I'd imagine that they would be fine. Personally I prefer Autolites because they perform very well in my car and they are cheap also, but to each his own.
