What is the method for adjusting spark plug gap?
1 Answers
The method for adjusting spark plug gap is: 1. Determine the standard gap value for your vehicle's spark plugs. You can use a large flat-head screwdriver with the spark plug metal casing as a fulcrum to pry; 2. Use a feeler gauge to find the appropriate metal blade that matches the spark plug gap; 3. Insert the corresponding thickness blade from the feeler gauge into the spark plug gap - if it fits snugly, it means the spark plug gap matches the blade thickness (multiple feeler gauge blades can be stacked if needed); 4. Select a 0.9mm or 1.0mm blade from the feeler gauge, place it between the spark plug electrodes, and use pliers to adjust until the blade fits snugly; 5. Repeatedly test with the feeler gauge until the blade fits properly.
