Universal Spark Plug Gap Tool with 32 Blade Gauge for 10mm-16mm Spark Plugs

Professional Spark Plug Gap Tool

Our SINGARO Spark Plug Gap Tool is designed to fit 14mm, 12mm, 10mm, and 16mm standard spark plugs, making it ideal for various applications, including chainsaws, string trimmers, and small equipment engines with short thread depths. Not compatible with 18mm threads or longer/shorter reach spark plugs.

Precision Measurement

Crafted from high-quality, flexible 65 manganese steel, this dual marked stainless-steel feeler gauge offers a measurement range of 0.001 inch to 0.04 inch (0.03mm to 1mm). Hardened and polished for long-lasting and accurate use, it is the preferred tool for any personal or professional machinery store or automobile garage.

Usage Tips

Due to the material of the spark plug, some electrodes may bounce back, which is normal. If your desired gap is 0.046 inches, we suggest using a 0.044-inch feeler gauge. For a smaller scale than your target gap, this automotive spark plug gap tool will meet your needs in a wide range of applications.

Easy to Use

Using our SINGARO tool is a simple process. Place the spark plug on the gapper, select the desired feeler, and slowly screw the knob until the side electrode reaches the desired gap thickness. Important: This tool only closes a gap; it does not open a gap.
