What is a Spark Plug Gap Tool?
A spark plug gap tool is a handy little device that measures the distance between the spark plug’s electrodes at the tip. For your car’s engine to work properly, this space is necessary. But why is it so important? Shall we begin?
Why is Spark Plug Gap Important?
The spark plug gap determines how the engine’s air-fuel mixture is ignited. Too big or too small of a gap can cause engine damage, misfires, and inefficient use of fuel. The gap must be exactly the right size, like in a Goldilocks scenario. Read Ultimate guide on how to jump start a car.
Types of Spark plug gauge gap tool
Feeler Gap Gauge
The spark plug feeler gauge is made of stainless steel and comes in a range of thicknesses. To determine the magnitude of the gap, you slide them between the spark plug electrodes. Easy and efficient!
Coin-style Gap Tools
Like a coin with numerals around its edge, these implements are easy to see. The size of the gap is indicated by the number that fits when you insert the edge into it. Convenient for portability!
Wire Loop Gap Tools
These are spherical implements that stick out wires of varying diameters. To get your measurement, you need to locate the wire that fits the gap.
How to Use a Spark Plug Gap Tool
It is easy to use a spark plug gap tool. Before you use your preferred gap gauge to measure the gap, take the spark plug out of the engine and clean it if needed. If necessary, gently bend the electrode to adjust the gap.
When to Check Your Spark Plugs
Every 30,000 miles, or as part of regular maintenance, you should check your spark plugs. Your car’s performance may be off, so it’s best to check them sooner rather than later.
How to Adjust Spark Plug Gap
To make the necessary adjustments to the gap, use the tool to slightly bend the electrode. It is recommended that you gently bend it out if the gap is too small. Adjust the width by bending it. Check the gap again after making any adjustments.
Common Mistakes When Gapping Spark Plugs
A common mistake is using too much force, which can damage the electrode. Not rechecking the gap after making adjustments is another. Here, consistency is key to winning.
