Silverline Spark Plug Gap Tool 0.5 - 2.55mm / 0.02 - 0.1" (202148)

Product Information

The gap can increase due to the continual heating and cooling of the spark plug. The electrodes can begin to wear down during normal operation of sending very high voltage between the electrodes. This can lead to gap to increase. Engine load and application — engines experience more cylinder pressure in the combustion chamber when under load as there is more air aspirated, making it harder to generate a spark. Some users claim that these are not as accurate as a feeler gauge, but I would have to disagree. These are just as accurate. But I do feel that a person must have some experience to use it properly. This spark plug gap tool works with 14MM spark plugs. I love this tool. It puts an end to banging it on the ground to close the electrode space, then prying it open, realizing you went too far, tapping it on the concrete again, etc.

The spark plug gap influences the heat range of the spark produced to ignite the air fuel mixture in the combustion chamber. This makes it critical to engine performance.Spark plugs that are properly gapped will burn at their best efficiency. The proper gap is not always what the manufacturer recommends. The OEMTOOLS Gauge is a precision tool designed to help you measure the gap between spark plugs and other critical areas on your engine. The most notable thing about this Lisle spark plug gap tool is that it gives you a wider measurement range than many options. It goes from .02 inches to .1 inches. No matter what kind of car you drive, the spark plug gap will be within this range. You can use this worry-free on any kind of vehicle. This is an old-style feeler gauge for setting spark plugs (and points, but since those cars are few and far between, I will focus on spark plugs). As different engines offer varied working environments, the style, size, and shape of the spark plug is influenced by factors like:

The CTA Tools Spark Plug Gapper has a heavy-duty construction built for strength and durability. It’s made up of a die-casted metal to harden the steel and increase the accuracy of the unit. It can be used for measuring and readjusting the spark plug gap. The gauge is calibrated in the imperial system, and the size markings are laser etched on the rugged steel construction. All feeler gauges are somewhat thin. This is because the point of them is to fit into and measure gaps that are far too narrow for most other common measuring tools, such as tape measures. Whether you’re a professional mechanic or a DIY enthusiast, you’ll appreciate the ergonomic design of the K-MOTOR Gap Tool.Engines with a high RPM give the distributor little dwell time to build up a solid spark, also making ignition tougher. The K-MOTOR Gap Tool is designed to provide the perfect gap between your spark plug electrodes. Not only does this help ensure that your engine runs efficiently, but it also prevents any potential damage to your spark plugs.
