Your opinion needed on this controversial question
its simple. question is: "do you apply 'anti-seize' when replacing your spark plugs?"
i have extensively searched forums to find this out. people's responses are about 50/50... and its quite controversial if i might add. opinions differ.
some folks say no because; bosch spark plugs already have the anti-seize plated on the thread, because with anti-size you can over tighten your plugs, and the anti-seize can increase spark plug temperature causing spark plug failure.
others say yes because; obviously avoids unwanted sparkplug issues, aluminum heads on MB engines, and some say they do it out of pure tradition.
What do Mercedes techs do?? do they apply anti-seize when changing plugs at the dealership??
Im doing my plugs this weekend.
My engine is: M272. my owners manual calls for sparkplugs: Bosch YR7MPP33
now, according to the WIS instructions, there is no call for anti-seize to be applied to thread upon spark plug assembly.
and according to Bosch, my plugs are no 'pre-plated' with the anti-sieze. the bosch tech guy also said to apply a dab on thread, spread evenly and tighten plug according to manufacturer's specs.
which leads us to the initial question: "do you apply 'anti-seize' when replacing your spark plugs?"
