The Engine Ignition Transformer Plug Extension is a cable assembly located on top of the engine cylinder head. It connects the ignition transformer, which is mounted on the engine block or valve cover, to the spark plug on the cylinder head. This extension is necessary because the spark plug sits within the combustion chamber and requires a longer reach from the ignition transformer.Attributes:• Delivers high voltage to the spark plug for ignition• Prevent current leakage and ensure the high voltageApplications: The Engine Ignition Transformer Plug Extension is a conductive pathway that transmits high-voltage electrical pulses from the ignition transformer to the spark plug.
