Mandark Car Spark Plug Gap Tool with 32 Blade Steel Feeler Gauge, Aluminum Spark Plug Gapping Adjustment Tool with Gapper for 10mm 12mm 14mm 16mm, Universal for Sedan SUV Van (Black)

["High Grade Material: This car spark plug gap tool is crafted from high-quality aluminum, featuring a robust and rigid construction with outstanding wear resistance. Its excellent corrosion and rust resistance ensures the tool maintains stable structural integrity during prolonged use, resisting damage and deformation.","Wide Application: This car spark plug gap tool is compatible with most standard 10mm/12mm/14mm/16mm spark plugs. However, it is not suitable for 18 mm thread and long reach or short reach spark plugs. Note: Please carefully verify spark plug dimensions before ordering to ensure compatibility and avoid usage issues due to mismatched sizes.","Easy to Use: First, select the feeler gauge matching your target gap. Slowly rotate the knob until the spark plug side electrode compresses to near the target gap. Then, slightly loosen the knob counterclockwise, remove the gauge, and remeasure the gap. If the target value isn't reached, repeat the steps until properly adjusted.","Adjustment Tips: This car spark plug gap tool enables efficient gap adjustment, making spark plug gap setting smoother. Note that some spark plug electrodes may rebound during gap adjustment. We recommend using a feeler gauge slightly smaller than the target gap. For example, use a 0.028-inch feeler gauge for a target gap of 0.030 inches.","What's Inside: The package contains 1 car spark plug gap tool, 1 32-blade feeler gauge, and 1 feeler gauge coin. The feeler gauges feature a robust, wear-resistant construction with high strength for long-term use. Multiple gauge sizes accommodate various spark plug gap measurements, enabling quick and convenient spark plug gap adjustments."]
