Toolwiz Spark Plug Gap Tool with 32 Blade Steel Feeler Gauge, Gapping Tool for Most 10mm 12mm 14mm 16mm Thread Spark Plugs, Red
- Wide Compatibility – Toolwiz spark plug gap tool is compatible with most 10mm, 12mm, 14mm, and 16mm standard spark plugs. NOT compatible with 18mm thread, long reach, or short reach plugs. Works for non-preset gap spark plugs; Iridium/Platinum spark plugs usually do not require adjustment
- Easy & Quick Adjustment – Toolwiz spark plug gapper saves time and effort when setting spark plug gaps. Just place the spark plug on the tool, choose the correct feeler gauge, and slowly turn the knob until the electrode compresses to the right gap. NOTE: This tool only reduces the gap, it cannot enlarge the gap
- Accurate Gap Setting – Some spark plug electrodes may spring back after adjustment. For best results, use a slightly smaller feeler gauge than your target gap (e.g., 0.028" if you need 0.030")
