Don't settle for approximate gap distances when you can achieve precision with our spark plug gap tool. Some spark plugs have electrode gaps that spring back, causing inaccurate measurements. We've got you covered - simply use a measurement 0.002-0.004 inches less than your target. For example, if you're aiming for a 0.016-inch gap, use a 0.012-inch to 0.014-inch measurement. When the spark plug springs back, you'll achieve the desired gap thickness with no hassle.

Using our spark plug gap tool is a breeze. Just place your spark plug into the gap tool, insert the feeler gauge of your desired gap thickness, and turn the knob until the electrode is compressed to the desired gap thickness. The tool even comes with a foldable feeler gauge made of 65 manganese steel. With 32 blades featuring dual metric and imperial markings, you'll have easy identification and a range of measurements from 0.0015 inch (0.04 mm) to 0.035 inch (0.88 mm). The feeler gauge is coated with a lubricant to prevent pitting and corrosion, ensuring its durability.

Still worried about the oil on the tool and the slight variance in distance when adjusting the gap? Don't be. The oil you see is simply anti-rust oil on the steel feeler gauge, designed to keep it in pristine condition. As for the spring-back effect on some spark plugs, just remember to use a measurement that is 0.002-0.004 inches less than your target to achieve the perfect gap.
