Kohler 4151921-s Ignition Coil

Product Description

The KOHLER 4151921-s is an OEM ignition coil designed for use in Kohler small engines. The ignition coil generates and delivers the high-voltage pulse to the spark plug at the correct moment in the combustion cycle, enabling reliable engine starting and consistent spark throughout operation. This is a direct-fit replacement part sourced from Kohler and is installed by small-engine technicians and equipment service professionals performing ignition system repairs or tune-ups.

This ignition coil is suited for outdoor power equipment powered by Kohler small engines, including applications commonly found in lawn and garden equipment. It is used when the original coil has failed, producing a weak spark, no spark, or erratic engine performance. Service technicians replacing ignition components as part of a diagnostic repair will find this coil appropriate for restoring correct ignition function.

Installation Notes

Ignition coil service on small engines is typically performed by trained small-engine technicians. Disconnect the spark plug wire and allow the engine to cool completely before beginning any ignition system work. The air gap between the ignition coil and the flywheel magnet must be set correctly during installation — consult the engine service manual for the specified procedure. Do not attempt to test coil output voltage by holding the spark plug wire with bare hands.
