NGK Spark Plug
Have anyone use NGK Irridium Plugs on M278 engine? Please share the NGK factory part number.
My 2013 E550 4Matic is in need for a tune up and I want to have NGK spark plugs for the replacement.

I don’t have a part # but I currently have NGK double-laser platinum spark plugs in my 2011 e550 (m273 engine) and everything works as it should. Highly recommend

The threads on the spark plugs for the M278 engine are indexed to the cylinder heads. Installing the plugs with the proper torque setting has the spark plugs properly positioned. Unless the spark plug you want to install is specified for the M278, I wouldn't suggest it.

Interesting I looked at the NGK website and they list plugs for indexing for my 2012 E350 but not for your 2013 E550.https://ngksparkplugs.com/en/part-finder
