I run them in my 88 s10 blazer 4.3 engine and 91 Bonneville 3600 engine.
My 72 Vette I run Bosch platinum because at the time Advance could not find a listing for them

Do a search on the forum. A few months ago someone posted a dyno test of rapid fire vs regular.

Guess what the results were...

I have the Rapid Fires in my '77. Very happy with them. As soon as I changed the plugs, I noticed an improvement. Maybe I would have gotten the same results from standard plugs, who knows?

I had to replace a plug in my car today. I use the rapidfire #2's they seem to work well for me.
