Hey! Anyone here using iridium spark plugs (any brand)? Used them on other vehicles that i've owned but not a Mercedes. So i don't know whether they would make much difference on these premium cars which are moderately modified. The brand I've used is NGK. I've heard of HKS also making them, but Denso seems to be everyone's choice.

everyone makes a iridium tipped plug now a days. I actually posted about this a while ago asking if the MB's got along ok with the Japanese plugs but didn't hear anything. I ran quad tipped iridium plugs in my M3 and never had a hiccup so I'm sure they are ok for the MB's.

Anyone know what comes standard from the factory? I'm guessing Bosch. anyone?
