Fuel Pressure Regulator Kit

The COBB Tuning Fuel Pressure Regulator Kit offers a straightforward, plug-and-play solution for 2008-2021 Subaru STI vehicles, aimed at resolving common drivability issues like the 2800 RPM stumble. This kit integrates an OEM Subaru fuel regulator with Dorman Quick Connect fuel fittings, ensuring compatibility and ease of installation without needing to cut factory hoses. Key features include multi-fuel compatibility and sheathing for enhanced abrasion resistance, making it a robust upgrade for performance-oriented Subaru models. The kit is designed to work with Stage 3 OTS Maps, but it is crucial to note that custom tuning is a mandatory requirement for all other setups to ensure optimal performance and engine health. Included in the package are the fuel pressure regulator, necessary lines, and installation hardware. While the installation is described as simple and easy, some users note that accessing the rear fittings can be challenging. This product requires custom tuning, and it is important to consult with a COBB Protuner to achieve the best results after installation.
