Are NGK Spark Plugs pre set?
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK also recommends adjusting the gap no more than +/- 0.008” from the factory preset gap.
How do you calibrate NGK Spark Plugs?
How do you calibrate a spark plug?
- Use a feeler gauge to check the gap of the spark plug.
- Choose the correct wire based on the size of the gap.
- Run the wire between the two electrodes of the spark plug.

How often should I change NGK Spark Plugs?
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor.

How do I know if my spark plugs are calibrated?
Measure the existing gap of the spark plug. Using your gap gauge or feeler gauge, run the tool through the electrodes to determine the measurement. Take note of the measurement and compare it to the recommended setting listed in the owner’s manual.
Should you lubricate spark plug threads?
NGK does not recommend the application of lubricant such as copper grease to spark plug threads as the result is a reduction of frictional forces at the thread faces. It’s very important not to over or under tighten spark plugs during installation. Over tightening can lead to distortion of the spark plug and breakage.
