They're great plugs. Interesting to note, iridium is one of the densest materials known to man. As for the plugs, they burn more efficiently due to them requiring less voltage to spark, they improve your idle and low end acceleration, better gas mileage, and more hp(1-2 not too much) If you're thinking about buying them just wait till your next scheduled tune-up. Get the most out of your current plugs if they're factory(they're platinum)Factory plugs will last you 75,000-100,000 miles.
