replace spark plugs

I now have a absolute 0 ignition fault

remember, if you have a very tuned engine, your sparks have to be replaced twice as fast

Seafoam your engine with the old sparks if you want the engine somewhat carbon clean

ONLY use

A0242236571 Bosch fr7ki332s

Keep your hand off the irridium pin, do not measure them with a metal blade !
they are made for the V12 biturbo CL600 and AMG CL65
preset is perfect

First, remove intercoolers, air filter
then remove the coilpack
spray W40 where the plugs are, wait 15 min
blow with air
Spray where the spark holes are again with break cleaner, plenty
blow the crap out

remove spark plugs

remove the red isulators
check, clean or replace

then use ONLY
