What is spark plug gap?
Categories: Engine Parts. Article Summary X. A spark plug gap is the distance between the end of the electrode and the base of the spark plug. If your spark plugs aren’t properly gapped, your engine may not burn fuel properly.
Why is it important to have a gapped spark plug?
A properly gapped spark plug is necessary for a properly functioning engine. The gap size affects the spark plug's firing temperature, which has a direct relationship to the combustion of fuel and air in the engine. Opening the gaps provides a larger spark, useful for some customized engines in maximizing the efficiency.
How to make a gap smaller?
If the gap is too small, pull the body of the plug away from the disc with the electrode hanging on the lip to gently force the gap open and re-measure it. If the gap is too big, use the broad side of the gap tool to push the electrode down and make the gap smaller.
How does a gap measure work?
A coin-style gap measure is usually the cheapest option, and works by running the edge of the "coin" through the gap until you reach a point where it stops. The edge is marked like a ruler, designating the thickness of the edge at that point.
What is a wire coin gap?
A wire coin gap works essentially the same way as the regular coin-style gap, but features different wire measures of varying lengths on the edge around the coin.
What is a blade gauge?
A blade-style feeler gauge is an effective and versatile tool. Built like a pocket-knife, this gauge features different blades of varying widths, some with wire on the end and some without, placed in the gap to check the spacing of the electrodes. You can also use multiple blades to measure larger gaps.
Can you fit a spark plug between electrodes?
If you can't fit it between the electrodes, the gap is too small and needs to be widened some. If it fits closely to the specified measurement, you're safe to install the spark plug. Most spark plugs and iridium plugs manufactured today don't need to be gapped prior to installing them.
