DeatschWerks 02+ Subaru WRX / 07+ STI/LGT Top Feed Fuel Rail Upgrade Kit w/ 1500cc Injectors

Starting with the 1500cc injector flow rate, this DeatschWerks fuel rail upgrade kit is built for Subaru models that need significantly more fuel than stock. The kit is designed for top-feed injectors, which offer a more direct spray pattern into the intake port compared to side-feed injectors. This setup is crucial for turbocharged or high-performance engines that demand a precise and ample fuel supply to avoid lean conditions and maximize power output.

The fuel rails themselves are constructed from well-built aluminum, ensuring they can handle the increased fuel pressure and flow without issue. They are designed to fit directly onto your 2002-2012 Subaru Impreza, 2007-2015 WRX STI, or 2007-2012 Legacy GT, replacing the factory components. This upgrade is a common step when building a more powerful engine, especially when paired with other performance modifications like turbochargers, intercoolers, and engine management systems. The kit includes all necessary components for installation, making it a comprehensive solution for your fuel system needs.

It's important to note that this kit is not CARB approved and cannot be shipped to California. Proper engine tuning after installation is essential to take full advantage of the increased fuel flow and ensure the engine operates safely and efficiently.
