When adding any modifications that increase the boost or horsepower in your Subaru or any car for that matter, you must upgrade your fuel system at the same time to supplement your engine with a proper amount of fuel. One of the biggest killers in a turbocharged engine is running too lean under boost which will cause you to lose your motor. 

These are the Injector Dynamics 1300cc fuel injectors that feature the latest in fuel injector technology and wizardry that makes these injectors the most popular among tuners. These are compatible with ethanol as well as most fuels such as alcohol, race fuels, and gasoline. These will come with new clips and pins to make them ready for installation.
