NGK offers a wide range of spark plugs, available in nickel and iridium . These spark plugs are available with different connections, such as SAE (fixed), Screw-on SAE, M4 and Frame SAE (fixed) . Choose the right spark plug for optimum engine performance and long life.

What should you pay attention to when choosing a spark plug?

Short vs. long shaft

The shaft length is crucial for the proper functioning of the spark plug. Always check the size of your old spark plug or measure the depth of the spark plug hole in the cylinder head before ordering a new one.

Heat degree

The heat range determines how much heat the spark plug can withstand. At higher engine power, a spark plug with a higher heat range is required . Too high a heat range can cause overheating, while too low a heat range can lead to increased fuel consumption and poor combustion.

Electrode gap

The correct electrode gap is essential for a good spark and optimum combustion. Too small a gap can lead to misfiring and bad exhaust gases, while too large a gap can cause engine problems. Always check the recommended gap for your engine.
