sp
ark plug tip for oblonging/uneven wear. Replace the
spark plug and corresponding cap if the wear patterns on
the cap terminal ring and spark plug terminal resemble the
photos below.

Spark Plug Cap Terminal Wear:
Use gentle force and a slight twisting motion when
in
stalling plug caps. An audible “click” should be heard
when the terminal ring is properly seated below terminal
tip indentation.
Spark Plug Wire Maintenance/Routing
Inspect each spark plug wire and the routing of both high
tension wires when performing spark plug maintenance.
Replace damaged wires/ignition coils if found.
Verify the
spark plug wires are routed as shown in the corresponding
photo below. Proper spark plug wire routing is critical in
preventing spark plug cap/wire wear.
