Ignition leads, found within the Engine Electronics section of Electrical & Lighting systems, deliver high-voltage current from the ignition coil to the spark plugs in both passenger cars and commercial vehicles. These leads are critical for combustion, ensuring efficient engine operation and optimal performance. Constructed with robust insulation and conductive cores, they withstand extreme temperatures and resist electrical interference. Variations exist to suit different engine configurations and spark plug locations. Examples in our catalog include MAN ignition leads, such as MPN 81274216052, 81619906127 and Scania part number 1774004. Proper functioning ignition leads are vital for maintaining emission standards and fuel economy.
