Bosch P/N for OEM spark plugs?



I believe you are in the US with a M271 engine. Mercedes part number is 004 159 23 03.
Bosch plugs for this car are (long number) 0 242 240 619 and (short number) FR6-MPP-332.
NGK plugs are (long) LFR6 AIX-11 and (short) 6619.
Many people find NGK plugs in their car from the factory. The short number is on the metal portion of the plug. You might not have Bosch plugs in your car.
