MAINTENANCE MANUAL LINE
Before every installation, the spark plug thread and the spark plug seat at the cylinder
head should be cleaned (e.g. to remove residue of heat conduction compound).
Installation
ATTENTION
Always replace both spark plugs of a cylinder and do not interchange spark
plugs between cylinders.
ATTENTION
Heat conduction compound at the ground electrode or the head area can lead to
ignition problems. Apply heat conduction compound sparingly and do not apply
to the first three threads.
Apply small amount of heat conduction compound to spark plug thread and tighten spark
plug to 16 Nm (142 in. lb) on the cold engine.
