Any particles that fall into the cylinder could cause serious engine damage.

Step 5

Repair step

⌕

Before installing the new spark plugs check that the spark plugs' gap is between 0.048 and 0.052 inches.
If it needs to be widened, use a gap setter to increase the size of the gap until it reaches the desired width.

Step 6

Wedge the new spark plugs into a 5/8'' spark plug socket.
Place the spark plug into the cylinder using the socket and hand tighten the spark plugs as much as possible.
Tighten the spark plugs to 13 ft-lbs with a torque wrench.
Do not over tighten spark plugs. This could strip out the threaded holes in the head.
