Durable alloy spark plug gap tool for accurate measurement and easy adjustment Key benefits Reliable long-term use: Made from high-quality solid alloy steel and die-cast for strength and resistance to deformation, so the tool stays accurate and serviceable over time. Fast, accurate readings: Clearly engraved gap scales are easy to read at a glance, helping you set correct spark plug gaps quickly and consistently. Built to last: Robust construction delivers good durability, with enough spring and flexibility to slide over electrodes without bending or breaking. Convenient, adjustable design: The round adjustment hole lets you set and fine-tune spark plug gaps. When not in use the tool can be hung from keys or a hook for simple storage. What it does for you Solves common ignition issues by making gap measurement and adjustment fast and repeatable, reducing misfires and poor engine performance caused by incorrect spark plug gaps. Eliminates guesswork: clear engraving and die-cast precision mean you don’t need extra gauges or repeated checks to get the gap right. Reduces tool replacement and workshop downtime thanks to tough alloy construction.
