Description
Oil coolers are essential for high-performance applications, but they can restrict flow during cold starts and cool-weather operation, extending engine warm-up times and reducing efficiency. The JAGG 4050 Automatic By-Pass Valve solves this problem by acting as a smart thermostat—automatically routing oil around the cooler until optimal operating temperature is reached, then seamlessly engaging cooling when needed. Whether you’re track-prepping on a cool morning or winter riding, this valve ensures your engine reaches peak operating temperature faster while maintaining full cooling capacity when it matters most.
