SPARK PLUG CABLE EXTENSION 17CM

Function and technical context

The 17 cm spark plug cable extension is a component of the ignition system that allows you to extend the electrical connection between the high voltage cable and the spark plug in those outboard or inboard engines where the standard length of the cable is insufficient due to the layout of the block or valve cover. Its function is to ensure the correct transmission of the high-voltage electrical impulse generated by the ignition coil to the spark plug electrode, without signal loss or interference. An extension cord in poor condition can cause intermittent misfires, jerky acceleration, unstable idling or even the total loss of spark in one or more cylinders, with a consequent drop in power and the risk of serious damage while sailing.

When to replace this part?

The most common symptoms of a damaged spark plug cable extension are sporadic misfire under load, abnormal engine vibrations, difficult starting when cold and high fuel consumption without apparent cause; Sometimes the connector shows burns, cracks in the insulation or visible corrosion on the metal terminals. It is recommended to inspect the extension cord during each seasonal maintenance and replace it at the slightest sign of degradation of the insulation or terminal, since heat, marine humidity and vibrations accelerate its aging. Replacing it preventively along with the spark plugs is the most recommended practice to avoid breakdowns at sea.
