Thumbs up Iridium Sparks

You guys might want to consider Iridium sparks next. I understand they are about two times more expensive but are more effective and lasts three times longer i.e. better value for money. When I replaced mine with Denso Iridiums, I experienced a considerably smoother engine (prob cuz they were new ) butalso response was more "explosive" - prob an extra 3-5hps at least I'm guessing

Thanks

I would suspect stringent emissions regulations; pertaining to LEV & ULEV emissions standards. MB's three-valve & twin-plug technology means cleaner engines. The two spark plugs per cylinder and the dual ignition system activates the twin plugs one after the other in quick successions "stagger" for cleaner-burning combustion & improve performance.

They're obviously still at the shop ......reading the tests on these things, there's an extra 4-6hps....here's your chance to get closer to the 300HPs you're wanting
