WARNING: The tapered seat plugs for this application are torque-critical! It is imperative that 17.5 Nm (13 ft. lbs.) is NOT exceeded!

NOTE: When replacing spark plugs and ignition cables, route cables correctly and secure in appropriate retainers. Failure to route ignition cables properly can cause the radio to reproduce noise, cross ignition of the spark plugs or short circuit the cables to ground.

CAUTION: Do not over apply anti-seize compound. Only use enough to lightly coat threads on the spark plug.

1. Apply a small amount of anti-seize to threads of each spark plug.
2. Check and adjust spark plug gap, [1][2]Spark Plug.
