Powerful Function: The spark plug gap tool provides a perfect gap every time. Simply place your spark plug on the tool; it's extremely easy and convenient to use. 3. Versatile Use: The heavy-duty spark plug gap spreader comes with a feeler gauge. You can use both to achieve the desired spark plug gap thickness, offering added convenience. 4. Springback Phenomenon: It's quite common for some spark plug electrodes to spring back. If your target gap is 0.44 mm, we suggest using a 0.42 mm tool. This will allow you to achieve a 0.44 mm gap when it springs back. 5. Recommendation: If the metal spark plug gap tool gets wet, you can use compressed air to dry it and apply lubricant (not included) to restore its performance.
