Bank transferThe Manual Oil Bypass Valve acts as a manual thermostat, allowing you to bypass the oil cooler for cold-weather riding or for faster warm-ups on cool days.
Compact in-line design installs between the oil source and the cooler and works with all oil coolers. The hand-adjustable knurled grip knob provides precise control.
Durable machined metal construction and compact footprint make installation straightforward. Made in the USA.
Important: If oil hoses between the oil cooler and the oil source are too short, the bypass valve may not fit. At least 3" of straight hose is required for proper installation.
