Product Advantage:

Sark plug is to introduce the pulse high-voltage electricity generated by the ignition coil into the combustion chamber, and use the electric spark generated by the electrodes to ignite the mixture, thereby starting the engine. ‌Iridium is a type of refined alloy highly suitable to be used as the materials of the central electrode in a spark plug. It ensures a more stable idle speed of the engine and faster starting up.

Package Include:

6 Pcs Spark Plug
