CAUTION:
Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged.

CAUTION:
The spark plug tubes (1) are a thin wall design. Avoid damaging the spark plug tubes. Damage to the spark plug tube can result in oil leaks.
Start the spark plug into the cylinder head by hand to avoid cross threading.
CAUTION:
Spark plug torque is critical and must not exceed the specified value. Overtightening stretches the spark plug shell reducing its heat transfer capability resulting in possible catastrophic engine failure.
Tighten the spark plug to the proper specifications. Refer to TORQUE SPECIFICATIONS .
Install the ignition coil. Refer to COIL, IGNITION, INSTALLATION .
