5.Measure the plug gap with a feeler gauge. Correct as necessary by bending the side electrode.

6.Check that the spark plug washer is in good condi- tion and thread the spark plug in by hand to prevent cross-threading.

7.After the spark plug is seated, tighten with a spark plug wrench to compress the washer. (See proper spark plug torque which is specified below).
