This is a factory-original OEM Eldor stick-style ignition coil designed to deliver high-voltage current directly to the spark plug for reliable combustion and throttle response. The pencil-style coil features an offset single-bolt mounting flange and an external wiring lead with a rubber-booted inline ferrite core noise suppressor. This helps reduce electromagnetic interference and protect sensitive ECU and dashboard electronics.
