The 84-821945A57 park plug cable set Compatible with Sierra 18-28082 Mallory 9-28082 Mercury Marine 84-813715A8
Function: The spark plug cable generates sparks by supplying current, igniting the mixture of gases in the cylinder of the car engine, enabling the engine to operate normally. If there were no sparks generated by the current transmitted through the spark plug cable, the engine would not work properly and the car would not be able to travel
Design and Materials: The design and material selection of spark plug cables also take into account factors such as resistance and durability to ensure effective current transmission under various working conditions, thereby ensuring reliable operation of the engine
