The Stens Ignition Coil for Kohler CH742 and CV742 ensures smooth starts and operation of outdoor power equipment. As an integral part of the ignition system, Stens ignition coils efficiently produce the high voltage necessary to generate the electric spark required for the spark plugs. By transforming the battery's low voltage to a higher voltage, ignition coils are a vital link in the system. Quality ignition coils will improve everything from quick engine starts to smoother engine performance. with well-made ignition coils, you'll benefit from a longer service life without stalls, misfires or other rough operation that can happen prematurely due to ignition coils of lesser quality. Stens uses premium materials and fine craftsmanship with superior windings and insulation to resist damage due to vibration, overheating and general wear common to outdoor power equipment. Because they must operate in harsh outdoor environments, Stens ignition coils are made to withstand extreme conditions.
