I second that, I did NGK Platinums (apparently the Laser Iridiums were not a correct fitment according to NGK, but I think that's probably incorrect) and I'm happy with them. They're one of the top manufacturers and most expensive, not by much but the few extra dollars you spend you definitely get a good plug.

I too can not find the proper ngk laser iridium plugs for my car. Yet I see a lot of people claiming that's what they use.

just pull the engine cover and intake ducts, then it's just like doing any other spark plugs. there is a two per cylinder, and the wires come lettered so you know which goes where because they are two different lengths in the front and rear cylinders.

why would you not use anti seize?

why would you not use anti seize?

Modern plugs don't require it, they have a special coating on the thread. Anti-seize can work its way into the cylinders, causing carbon build up & plug fouling.

Thanks, however, nothing in that video re the wrench. He just pulls the wires off the plugs by hand.

I just checked the specs on that plug. The gap, heat range and reach do not match requirement for mercedes plugs. I might just go with the laser platinums.
