## Description

The CTA Tools 3235 Spark Plug Gapper is a compact, coin-style tool designed for quick and convenient spark plug gap checks during routine maintenance and tune-ups. With an easy-to-read scale and simple ramp-style design, it allows users to quickly verify spark plug gaps without complicated setup or additional tools. This gapper measures gap sizes from 0.020" to 0.100", covering most automotive, powersports, and small-engine applications. Constructed from durable, corrosion-resistant plated steel, it is built to withstand repeated use while maintaining reliable performance over time. Its slim, lightweight design fits easily in a pocket or toolbox, making it ideal for use in the shop, garage, or on the go. The CTA Tools 3235 is intended for general service and quick-reference use, helping ensure proper ignition performance and smoother engine operation during everyday maintenance. It provides approximate gap verification within normal service tolerances and is well-suited for fast inspections and adjustments. Important Usage Note: This spark plug gapper is a quick-check reference tool and is not designed for calibration-grade precision. Minor measurement variances are normal and acceptable for general service. For applications requiring exact gap measurements to the thousandth of an inch (such as 0.028" or 0.71 mm), a precision feeler gauge should be used for final verification. Whether you’re performing routine maintenance, diagnosing ignition issues, or making quick checks between runs, the CTA Tools 3235 Spark Plug Gapper delivers reliable, fast, and convenient results you can count on.

Review: Simple Design, Good Quality - While you can certainly use small calipers to measure spark plug gaps, this tool is an effective, inexpensive way to get the job done - plus you don’t need any battery/power. It seems like every time I go to use my caliper I need a battery lol. You just insert the gap tip in the hole and you can turn the plate until you determine you are at the right gap.
Review: Good gapper - I bought this and gapped a set of plugs to manufacturers specs. I can’t say whether it is absolutely accurate, I didn’t put the micrometer on it to find out, but my vehicle started and ran just fine. 😉 I’d Venturi say it’s pretty close.
