Jims USA Forceflow Cylinder Head Cooler

Smooth, streamlined design will keep your Twin Cam running cooler on those hot summer days in stop and go traffic. Jims R&D department has come up with a serious way to drop your head temperature by as much as 100 degrees! Although this mounts in the horn location, JIMS has relocated a horn inside the fan housing for a clean installation that doesn't sacrifice function. The fan itself can be configured for manual or thermostat-controlled on/off functionality. The thermostat switching configuration monitors cylinder head temperature and activates the fan when engine temperature reaches 140 degree.

Highly recommended for performance Harley-Davidson motors, this kit will help extend engine life and increase running reliability, regardless of where or how you ride. Each kit includes a high-powered fan, fan housing, horn, hardware and all wiring, along with detailed installation instructions.
