2.4 Spark Plugs

Reset the spark plug gap or replace the plugs with new
plugs as necessary.
1. Clean the area around the base of the spark plug
to keep dirt and debris out of the engine.
2. Remove the spark plug and check its condition.
Replace the spark plug if it is worn or if its reuse
is questionable.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.76 mm (0.030 in.) by
carefully bending the ground electrode.
Figure 2-7 and Figure 2-8.
4. Reinstall the spark plug into the cylinder
head. Torque the spark plug to 24.4–29.8 Nm
(18–22 ft. lb.).
