The CTA Tools Spark Plug Gap gauge is made up of a strong and durable all-steel construction built to resist corrosion. 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. Nine wire rings on the gauge's outer edges help you to accurately measure, increase, and decrease the gap size. Next, let’s see how you go about gapping a spark plug to its recommended gap. How To “Gap” Spark Plugs (Step-By-Step) Fuel type and concentration — fuel with a higher alcohol content requires a lower air fuel ratio and a narrower spark plug gap.

Now, you may wonder why you’d need to measure the spark plug gap, especially on a new plug. Why Should I Measure The Spark Plug Gap? Ease of Use: If you have limited experience setting spark plug gaps, look for an easy tool. A tool with a clear scale and easy-to-adjust settings is a great choice. 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. And while the spark plug is a pretty simple piece of equipment, it has to work in very tough conditions. Durability: Spark plug gap tools can take a beating, especially when used in tight engine compartments. So it’s important to look for a tool made of durable materials that can withstand the rigors of the job.

The manufacturer will most likely gap the plugs to the most common setting. Silver spark plug: Silver is definitely a better conductor compared to the others. It’s also more durable. Be careful when adjusting it. It’s a rare type and found mostly in old model cars. Some users have complained that the oil on the blades makes them very slippery to work with. But the oil is necessary to protect the blades from rusting. I suppose if this bugs you, you could wipe them off with a clean rag, then reoil them when you are finished working.Warranty: Look for a tool that comes with a good warranty. You can get something fixed or replace without spending extra money if something goes wrong. Multiple electrode spark plugs are vehicle-specific and come with a factory gap that isn’t adjustable.

If you’re looking for a comprehensive tool that can measure any spark plug gap, you’ll love this steel gap measuring tool from Hotop. It gives you 32 precise measurements, ranging from a width of .04 to .88 mm. The blades also include imperial measurements, making this tool incredibly versatile. Setting the gap on spark plugs was one of the first things my father taught me to do when working on cars. This process was so simple. I was only 8 or 10 years old at the most and I learned to do it in about 5 minutes.If it turns out you do need to adjust the gap, you don’t need to necessarily buy the best spark plug gap tool to do so. Needle nose pliers make a great homemade spark plug gapper. They’re the recommended spark plug gap tool for iridium, but they can also work for other spark plug styles. As with the advice above, the first thing you should do is make sure you need to gap your spark plugs. If you bought spark plugs recommended for your vehicle, they’re likely gapped to the correct specifications already from the factory. Finally, let’s look at this wire-style gauge tool from CTA. This style of gapper was designed to be gentler and more accurate than coin-style gap tools. If you use iridium spark plugs, a tool such as this one is likely your best option for smooth and damage-free adjustment. 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. If the feeler gauge won’t go between the two electrodes, the space between them needs to be opened. Use the tool on the spark plug gap tool to open the electrodes, but just a very tiny bit. You can always make the opening wider if it is still too small, right?

And thirdly, the same spark plug can be specified for many different engines, but each engine may require a different gap size. 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.
