Spark Plug: 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 N.m (20 ft. lbs.) torque.
3. Install spark plug insulators over spark plugs.
