Autolite XP spark plugs.

[Cerwin Vega Fan]

Just got these new spark plugs in at work and I was wondering if anyone has tried them yet?

I am interested to find that out too. I've seen them advertised at my local parts store.

Iridium plugs rule. I've heard this straight from the R&D engineers I know at Champion and NGK. They work very well for performance applications. you have clearance to spend your hard-earned money (as long as your wife says it's OK)

Iridium plugs do seem to showing sign of success. I have been staying in touch with the engine shop manager at Rousch Engineering (the guy I bought my bike from) and they have been testing the Iridium's with some of the NASCAR and IRL cars and they have had great success so far. They have the ability to provide a more potent electrical impulse without increasing the heat range much.
