    Fuel System

    With a high-quality fuel system from Subispeed, you can guarantee optimum fuel distribution and performance in your Subaru. Our fuel system components are made to better control fuel flow and pressure while also supporting applications that demand higher horsepower. We offer a variety of choices to meet your unique demands, whether you want to adjust your gasoline pump, fuel injectors, fuel rails, or fuel pressure regulator. Without a working fuel system, your Subaru WRX, STI, Forester, or Crosstrek cannot generate its maximum power, burn gasoline effectively, or perform consistently. Choose from well-known manufacturers that are renowned for their great performance and quality, such as Cobb Tuning, Injector Dynamics, and DeatschWerks.
