Since anti-seize compounds contain metallic, electrically conductive ingredients, the ingredients can come in contact with the electrodes on the spark plugs, leading to misfires.Ĭan you use aluminum anti seize on spark plugs? Should I use anti seize on Autolite spark plugs?Īutolite does NOT recommend the use any type of anti seize lubricant when installing new Autolite spark plugs. Using a spark plug gap tool allows you to achieve the exact measurement recommended by the manufacturer. Why You Should Use a Spark Plug Gap Tool Whether you’re looking to maximize the performance of your vehicle or just want to double check that the setting is right, using a spark plug gap tool is vital. Gapping has always been the job of the installer. Because of the many gap sizes required, no one offers spark plugs properly gapped for every application. Anyone attempting to measure or change a spark plug gap should have a spark plug gap chart handy.Autolite® and all spark plug manufacturers offer spark plugs pre-gapped in the most popular gap sizes. It can also be a reference for measurement conversions when determining the size of an existing spark plug gap using a gauge.

With a gap that’s too big or too small, you’ll notice quickly that your engine (and, by extension, riding experience) is rougher and riddled with hesitancy and strange engine noises.Ī spark plug gap chart can be used to determine what the ideal spark plug gap is for specific vehicles or engines. With an ideal spark plug gap, things will run smoothly. How does the spark plug gap affect performance?Ī spark plug’s gap affects performance by changing how an engine starts, runs, and idles. You can identify a spark plug with a gap that’s too big on sight by it being wet or black due to unburned fuel or completely coated in a substance that looks like dirt.ħ. Much like with a spark plug gap that’s too small, symptoms of a spark plug gap that is too big include cylinder misfires, rough idling, engine hesitation, and the engine not starting. This can cause engine performance issues. The engine can’t always provide the extra voltage needed to cross the gap, so the spark is weaker and won’t ignite your fuel mixture properly. If the spark plug gap in your vehicle is too big, the spark plugs will need a higher voltage to get the ignition spark to cross the gap. What happens if the spark plug gap is too big? Having the ideal spark plug gap in your vehicle ensures your car runs more smoothly.ĥ. If your vehicle’s spark plug gap is too big or too small, this can cause issues with engine performance or even prevent your engine from starting.

A way to recognize a spark plug with a too-small gap on sight is that it will be black or wet due to unburned fuel.Ī smaller spark plug gap is not better because a gap that is too small can prevent the vehicle’s fuel mixture from being ignited and create engine performance issues. Symptoms of a spark plug gap that is too small include continuous cylinder misfires (which can sound like knocking or popping), hard starting (if all spark plugs have a gap that’s too small), engine hesitation, and rough idling. Several engine issues result from a spark plug gap that is too small. The spark generated by a smaller spark plug gap is sometimes too weak to start the engine. If the spark plug gap in your vehicle is too small, the spark won’t have enough exposure to the fuel mixture to properly ignite it. What happens if the spark plug gap is too small?
