Spark Plugs: Installation

  1. To avoid cross threading, start the spark plug into the cylinder head by hand. The tapered seat plugs for this application are torque-critical. It is imperative that the specified torque is not exceeded. See TORQUE SPECIFICATIONS .
  2. Install spark plug insulators over spark plugs. Ensure the top of the spark plug insulator covers the upper end of the spark plug tube. Install spark plug cable to coil. See Figure. Install the upper intake manifold. See appropriate article in ENGINES.
  3. Reconnect the negative battery cable. Install the air cleaner lid, and connect the inlet air temperature sensor and air hose.


NOTE: Install cables to the spark plug first before installing them to the ignition coil.
