Engine Coolant Return Pipe (304 Stainless Steel)

Specifically designed for use in conjunction with the factory thermostat housing. 304 stainless steel construction prevents corrosion compared with OEM mild steel pipe which is prone to rusting and eventually leaking. Allows for installation of factory turbo coolant return thermostat. Also great for marine applications.
