Sierra 18-5435 Marine Ignition Coil with Internal Resistor for Chrysler Inboard 4-Cylinder 1C Engines, 1959-72 and 1959-73

The Sierra 18-5435 is a marine ignition coil built with an internal resistor, designed to deliver reliable spark energy for the ignition system on applicable inboard engines. It is designed for use with Sierra's 18-5469 High Performance Ignition Coil. The coil carries a primary resistance of 2.70/3.36 Ohms and a secondary resistance of 7,560/9,410 Ohms, with an inductance rating of 10.6/13.0 MHY, matching the electrical characteristics required for correct spark output on the engines it fits. It uses a screw-in installation type with a male connector gender for straightforward wiring at the distributor.

This coil is intended for Chrysler Inboard 4-cylinder 1C model engines, matched to Distributor No. IGW-4118A on 1959-72 applications and Distributor No. IGW-4301 on 1959-73 applications. It is interchangeable with CDI E18-0005, Chrysler Inboard 200691, Crusader 41080, and Mallory 9-29703 coils, giving buyers multiple cross-reference points to confirm fit. Sierra states that each of its products meets or exceeds the original equipment part it replaces.
