Special care should be taken when installing spark plugs into cylinder head spark plug wells. Be sure plugs do not drop into plug wells as ground straps may be bent resulting in a change in plug gap, or electrodes can be damaged.
Always tighten spark plugs to specified torque. Over tightening can cause distortion resulting in a change in spark plug gap or a cracked porcelain insulator.
1. Verify that each plug is correctly gapped to 0.035. Apply a small amount of anti-sieze to the plug threads. Start spark plug into cylinder head by hand to avoid cross threading. It's best to do this by using just the socket extension bar and socket. Carefully turn slowly while keeping the extension bar as vertical as possible. You should be able to screw the plug all the way in by hand until it "seats" snugly.
2. Tighten spark plugs to 26-30 ft. lbs. (35-41 N·m) torque. If you do not have a torque wrench install plugs snug and then turn 1/4 turn.
3. Connect engine harness connector to coil by snapping into position. Move slide tab towards engine for a positive lock.
4. Position ignition coil rubber boots to all spark plugs. Push down on coil assembly until bolt bases have contacted cylinder head.
5. Install 4 coil mounting bolts. Loosely tighten 4 bolts just enough to allow bolt bases to contact cylinder head. Do a final tightening of each bolt in steps down to 250 in. lbs. (29 N·m) torque. Do not apply full torque to any bolt first.
6. Connect negative battery cable to battery.
