Spark Plug NGK BR8EIX Iridium (5044)

Spark plug function

Spark plugs play an very important role in the performance of your engine, whether on a scooter, moped or motorcycle. It generates the spark necessary for igniting the air-fuel mixture and provides information about the carburetor settings. If the spark plug is defective, the engine jerks and may start sluggishly or not at all.

Reach and heat value

There are spark plugs with a short thread or reach (marked "H") and spark plugs with a long thread (marked "E"). Spark plugs have a specific heat value, where cold spark plugs with a high number are more suitable for high performance engines, while hot spark plugs with a low number are more suitable for original engines.

For optimum performance and reliability, it's important to choose the right spark plug for your setup and make sure the spark plug cap is working properly.
