Jagg Offset Oil Filter Adapter with Thermostatic By-pass for H-D Twin-Cam

Part # 4700

$ 170.00

The Jagg #4700 Offset Oil Filter Adapter with Thermostatic Oil By-pass installs between the engine and oil filter for quick and easy installation of a Jagg oil cooler. The #4700 directs oil through the filter first for optimal flow characteristics.

After filtration, the oil will by-pass the oil cooler until the engine reaches standard operating temperature. Once the bike reaches operating temperature, the thermostatic actuator will close the #4700’s by-pass hole, sending hot, filtered oil to the oil cooler, and delivering cool, clean oil to the engine.

Oil flow direction from adapter: oil feeds the oil cooler from the fitting on the left side and returns to the fitting on the right side, as viewed from front with oil filter adapter fittings at bottom.


The #4700 Offset Oil Filter Adapter was designed especially to fit H-D Twin-Cam motors. Also fits fuel-injected Big Twin EVOs.
