This CTA gap adjustment tool only weighs 1.44 ounces and will offer over 30 accurate gaping measurements before you need to readjust it. Nine wire rings on the gauge's outer edges help you to accurately measure, increase, and decrease the gap size. It’s a circular gauge with easy-to-read, laser-etched sizes on its body in sizes ranging from 0.025 to 0.060 inches with 0.005 increments. The CTA Tools Spark Plug Gap gauge is made up of a strong and durable all-steel construction built to resist corrosion. The products also contain harmful chemicals known to cause reproductive harm by the state of California. Also, it’s made of cheap quality steel that may rust, and the size markings may fade with time. You may have to use another tool to confirm the small differences in values. However, this gapper may not be as accurate as advertised, and it may not give precise measurements for reducing the size of the spark plug. The tool can measure the clearance of any spark plug model.
The hole helps you accurately resize spark plugs with an electrode tool included. The gapper is also designed with a key ring hole or a spark gap opener with a 7/16 inch diameter. The sizes range from 0.02 to 0.1 inches with 0.01 increments, and they are easy to read. The gauge is calibrated in the imperial system, and the size markings are laser etched on the rugged steel construction. It can be used for measuring and readjusting the spark plug gap. It’s made up of a die-casted metal to harden the steel and increase the accuracy of the unit. The CTA Tools Spark Plug Gapper has a heavy-duty construction built for strength and durability. You may have to tighten the thumbscrew to keep the blades intact. Also, the blades may come apart if dropped. You may notice that the blades are oily upon delivery, and you need to keep on lubricating them to prevent rust. That’s easy to carry around in your pocket or in a toolbox.ĭespite being made of steel, these blades can rust when stored in humid conditions. The blades have smooth edges, and all 26 blades only weigh 3.2 ounces.

The OEM Tools Blade Master has 26 calibrated blades that can measure sizes ranging from 0.0015 to 0.025 inches. Types of Spark Plug Gap Tools Feeler Gauge If the gap is not properly aligned, the electrode will continue to discolor and will eventually burn away. Further inspection may reveal that the gap between the ground electrode and the center electrode is wider. Used spark plugs may have a slight discoloration at the electrode (negative probe).

A new spark plug may not have the same gap size, and if you install it with a smaller or larger gap, you may notice a significant decline in your engine’s performance. These plugs have a designated ignition gap, heat range, and torque that works for your engine. Your original spark plug may come pre-gapped by the manufacturer. That way, you boost the efficiency of the spark plug in putting out a large enough spark to ignite the air and fuel mixture in your engine. The gapping tool will help you manually open the gap to the exact factory measurement recommended in your owner's manual. The size of the gap of a spark plug determines its firing performance. Achieve better spark plug performance.
