Jims Forceflow Cylinder Head Cooler Black 1999-2016 Harley Touring 5401

Twin Cam engines generate serious heat under sustained throttle, and factory cooling falls short during extended riding or track use. The JIMS Forceflow Head Cooler delivers targeted airflow directly to your cylinder heads, maintaining optimal operating temperatures and preserving power output when it matters most. This plug-and-play solution integrates seamlessly into your stock setup without fabrication, giving you professional-grade thermal management in minutes.

The automatic temperature switch activates the high-powered fan at 140°F, then a manual override lets you dial in cooling on demand. You'll see measurable improvements in engine longevity, consistent jetting across ride conditions, and peak performance during aggressive riding. Installation requires no drilling or custom brackets—everything bolts directly to your existing horn mount location.
