When removing spark plugs, remove and install one at a time or label the ignition wires before removal to avoid mixing up the firing order.
If the engine has been run recently allow the engine to cool down before removing spark plugs.
Make sure ignition cables are routed correctly otherwise radio ignition noise, spark plug cross ignition or a short circuit to ground may result.
Always remove the spark plug cable by grasping the top of the spark plug insulator, turning the boot 1/2 turn and pulling straight up in a steady motion.
Disconnect ignition wire from ignition coil.
Disconnect spark plug cable from spark plug.
Use compressed air to clear debris from area around spark plug
Remove the spark plug using a quality socket with a rubber or foam insert.
Apply thin layer of anti-seize lubricant to spark plug threads.
To avoid cross threading, start the spark plug into the cylinder head by hand.
Tighten spark plugs to 13 ft. Lbs. (17.6 Nm).
The tapered seat plugs are torque-critical! Do not exceed 13 ft. Lbs. (17.6 Nm)!
Install spark plug insulators over spark plugs. Ensure the top of the spark plug insulator covers the upper end of the spark plug tube.
Reconnect to coil.
