For those seeking maximum performance, the valve can be set to allow more oil flow during hard driving, while still preventing backflow when the engine is idle or off.

Installation of the RS-30A Check Valve is a straightforward process, requiring no major modifications to your engine or cooling system. It is designed to fit seamlessly into the existing oil cooler inlet, making it an easy and cost-effective upgrade for any Porsche enthusiast.
