2. NOTE: Two different spark plug gaps are used.
Check and adjust spark plug gap(s) with a plug gap gauging tool (1)See: Specifications/Spark Plug Specifications.
3. NOTE: Do not drop spark plugs into the plug wells as electrode damage can occur.
Using special care install spark plug(s) into the cylinder head by hand to avoid cross threading.
NOTE: Always tighten spark plugs to the specified torque. Certain engines use torque sensitive spark plugs. Over tightening can cause
distortion resulting in a change to the spark plug gap, or a cracked porcelain insulator.
CAUTION: Due to tight clearances between upper row of plugs (5) and cylinder head, a conventional deep, thick-wall spark plug socket will
not fit. Use a deep, THIN-WALL 5/8" spark plug socket for plug removal and installation.
4. Tighten spark plug(s) to the specified torque See: Specifications/Spark Plug Specifications.
5. Install ignition coil(s) See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Ignition Coil - Installation.
6. Install necessary air filter tubing and air intake components to top of engine and to throttle body.
