Spark Plug: Adjustments

Setting Spark Plug Gap - Typical:

Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or oil fouled.

CAUTION: The Platinum pads can be damaged during the measurement of checking the gap if extreme care is not used.
- Use only a taper gap gauge
- Never force the gap gauge through the platinum pads. Only apply enough force until resistance is felt.
- Never use a wire brush or spark plug cleaner machine to clean platinum spark plugs
- Use an OSHA approved air nozzle when drying gas fouled spark plugs.

If gap adjustment is required of platinum plug, bend only the ground electrode. DO NOT TOUCH the platinum pads. Use only a proper gapping tool and check with a taper gap gauge.

CAUTION: Cleaning of the platinum plug may damage the platinum tip.
