Spark Plug: Service and Repair

REMOVAL
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.

1. Remove the spark plug using a quality socket with a rubber or foam insert.

INSTALLATION
Failure to route the cables properly could cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the cables to ground.

1. To avoid cross threading, start the spark plug into the cylinder head by hand.
2. Tighten spark plugs to 27 Nm (20 ft. lbs.) torque
3. Install spark plug insulators over spark plugs.
