PLUG VISC REG FLOW

Replaces thermostatic actuator element in offset oil filter adapter with new Viscosity Regulated Flow (VRF) actuator 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 by-pass hole closed, sending hot, filtered oil to the oil cooler, and delivering cool, clean oil to the engine Made in the USA Kit Includes: One viscosity regulated flow plug One spring One button head One O-ring One Gasket
