Hot Champion plugs

Hey all, does anybody have beef with champion plugs. I am thinking of using the hottest they make for the 460. RF14Y7. I have about 9:68:1 compression and want to zapp all of that fuel. Better suggestions?

Hottest aint always the best...what cyl heads do you have .

Something that crosses over to about a 45 autolite .

I wouldn't use Champions to plug a heater hose. The only time I did use them, six out of eight leaked compression past the porcelain. Never used them again. Try Autolite!

You beat me to that quote. A guy brought me a set to tune his 03 Mercury Sable last week. I told him to get them outa my shop. I agree, go w/Autolite/ Motorcraft.

I used them once in my 302 Boss and by the time it took me to drive from the pits to the staging lanes the went to misfiring, lost that final so never again......

Thanks guys. My father is a mechanic of 40 years and says the same thing about the champion. Its hard to listen sometimes.

Back in the '50s, CHAMPIONES were the plugs to run. Somehow, by the late '60s, they weren't. Back then they would give racers 2 boxes a week if you went to their local warehouse and asked. We bought AUTOLITE plugs.

I use champions in the propane burner and motorcraft in everything else.

Yep thats proly it alrite

A good ignition will do more for you than hot plugs. The dura spark or a msd6a and some good autolites will do a good job for you. The only exotic plugs I ever use are the irridium on boosted motors. In those motors they hold up like iron.
