THE JIMS FORCEFLOW CYLINDER HEAD COOLER This smooth streamline design will keep your Twin Cam® running cooler on those hot July 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 area JIMS has designed a horn relocater hidden inside the fan housing. The fan can be installed to be turned on and off manually or it can be regulated by a thermostat controlled sensor that monitors head temperature and activates the fan when engine tem- perature rises. This kit is highly rec- ommended for performance motors to help extend engine life. Complete kit includes high pow- ered fan, housing, horn, hardware and all wiring, along with detailed instructions. For more details see No. 5400-IS instructions. USE ON 99-PRESENT TWIN CAM TOURING MODELS & OTHER MODELS WITH SOME FABRICATION. (Kit installs from horn location & is supported by center case bolt location.)

It’s common knowledge that heat is one of an engines worst enemies. In developing

the JIMS cylinder head cooler, JIMS had to sacrifice a few motors for the cause. We tested worse case scenario by letting engines idle in the sun for over a half hour each while recording cylinder head temperatures minute by minute. Above represents the average

temperature reduction of all testing combined. The JIMS Cylinder Head Cooler will help an engine operate and stabi- lize at lower temperatures.
