The importance of proper spark plug gap cannot be overstated in the world of automotive maintenance. Spark plugs are responsible for igniting the fuel-air mixture in an engine, and a gap that is too wide or too narrow can lead to a range of issues, from decreased fuel efficiency to engine damage. In this article, we’ll explore the question of whether a feeler gauge can be used to gap spark plugs, and provide a comprehensive guide on how to do it correctly.
What is a Feeler Gauge?
A feeler gauge is a simple, yet essential tool used to measure the gap between two parts, in this case, the spark plug gap. It’s a thin, flexible strip of metal or plastic with markings on it, used to measure the distance between two points. Feeler gauges are commonly used in various industries, including automotive, aerospace, and construction.
Why Use a Feeler Gauge to Gap Spark Plugs?
There are several reasons why a feeler gauge is an excellent tool for gapping spark plugs:
- Accuracy: A feeler gauge provides an accurate measurement of the spark plug gap, ensuring that it’s set to the manufacturer’s recommended specification.
- Convenience: Feeler gauges are easy to use and require minimal equipment, making them a convenient option for DIY enthusiasts and professionals alike.
- Cost-effective: Feeler gauges are relatively inexpensive and can be used multiple times, making them a cost-effective option compared to other gapping methods.
How to Use a Feeler Gauge to Gap Spark Plugs
Using a feeler gauge to gap spark plugs is a relatively simple process:
Step 1: Remove the Spark Plug
Start by removing the spark plug from the engine. This will give you clear access to the spark plug gap. Be sure to wear protective gloves and safety glasses when working with spark plugs.
Step 2: Inspect the Spark Plug Gap
Inspect the spark plug gap to ensure it’s free of debris and corrosion. Use a soft-bristled brush or a cloth to clean the gap if necessary.
Step 3: Select the Correct Feeler Gauge
Choose a feeler gauge that matches the recommended spark plug gap specified in your vehicle’s repair manual. If you’re unsure, consult with a mechanic or the manufacturer’s website. (See Also: Is There Any Spark Plug in Diesel Engine? Explained)
Step 4: Insert the Feeler Gauge
Insert the feeler gauge into the spark plug gap, making sure it’s seated properly. Gently push the gauge into the gap until it reaches the desired measurement.
Step 5: Check the Measurement
Check the measurement on the feeler gauge to ensure it matches the recommended spark plug gap. If the gap is too wide or too narrow, adjust the spark plug accordingly.
Step 6: Reinstall the Spark Plug
Once the spark plug gap is set to the correct measurement, reinstall the spark plug and ensure it’s securely tightened.
Alternative Methods for Gapping Spark Plugs
While a feeler gauge is an excellent tool for gapping spark plugs, there are alternative methods available:

FAQs
Q: Can I use a feeler gauge on all types of spark plugs?
A: No, not all spark plugs are compatible with feeler gauges. Some spark plugs have specialized gaps that require a different type of gapping tool. Consult with your vehicle’s repair manual or a mechanic to determine the best gapping method for your spark plugs.
Q: How often should I gap my spark plugs?
A: The frequency of gapping spark plugs depends on the type of spark plugs and the vehicle’s manufacturer recommendations. Typically, spark plugs should be gapped every 30,000 to 100,000 miles, depending on the type of spark plugs and driving conditions.
Q: Can I gap my spark plugs myself?
A: Yes, gapping spark plugs is a relatively simple process that can be done by a DIY enthusiast with the right tools and knowledge. However, if you’re unsure or uncomfortable with the process, it’s recommended to consult with a mechanic or a professional auto repair shop.
