Replaces thermostatic actuator element in the Jagg 4700 offset oil filter adapter with new Viscosity Regulated Flow (VRF) actuator. Includes gaskets & O-rings to reseal 4700.

The #AK4700-VRF installation converts a Jagg #4700 offset oil filter adapter into a Jagg #4701 offset oil filter adapter with Viscosity Regulated Flow.

After filtration, the oil may either travel to the oil cooler or by-pass the oil cooler, according to the built-in Viscosity Regulated Flow (VRF) plug function. Cold, viscous oil will by-pass the oil cooler, speeding warmup to standard operating temperature. As the engine reaches operating temperature and oil reaches optimal viscosity range, the VRF plug will keep the #4701’s by-pass hole closed, sending hot, filtered oil to the oil cooler, and delivering cool, clean oil to the engine.

Includes:

• Viscosity Regulated Flow Plug
• Spring
• Button head with O-ring
• AFM Gasket for 4700
• Large O-ring for 4700
