Description

The COBB In-Tank 4.5 bar Fuel Pressure Regulator is a simple modification that greatly increases the capability of your cars fuel system. Increasing pressure in the low pressure side of the system helps to mitigate cavitation when your car's High Pressure Fuel Pump (HPFP) is producing maximum flow.

Note for 2026 WRX USDM: This product is not available for sale in California at this time. Stay Tuned as we work towards CARB approved 50-State status.

Why?

Upgrading the in-tank fuel pressure regulator can help to prevent cavitation at your car's High Pressure Fuel Pump. The COBB regulator increases pressure to 4.5 bar, suitable for most applications.
