The Universal Spark Plug Gap Adjuster Tool provides a reliable and accurate solution for adjusting the gap of spark plugs. It is compatible with most 10mm, 12mm, 14mm, and 16mm spark plugs, including models like NGK 6061, NGK 5671A, and NGK BKR9EIX.
Built with a sturdy black anodized aluminum body, this tool features threaded adjustment for precise gap settings. Note: It is not compatible with 18mm thread or longer-style spark plugs.
Usage Tips:
If the spark plug electrode springs back after adjustment, we recommend setting the gap slightly smaller than the target value. For instance, if your target gap is 0.40mm, set it to 0.38mm to achieve the desired result. Results may vary depending on the spark plug brand, manufacturer, and material.
Application:
- Suitable for most 10mm, 12mm, 14mm, and 16mm spark plugs.
- Maintenance Tip: The steel surface may oxidize if exposed to water. After exposure to moisture, dry the tool with compressed air and apply lubricant.
Package Includes:
- 1x Spark Plug Gap Adjuster Tool
