Proper fuel flow at the injector is critical for engine tuning and performance. When you're adding bolt-on power adders like superchargers, turbo kits, cams, nitrous or even a simple intake manifold swap a larger injector is necessary. Injector flow rate and efficiency is important to make sure the air fuel ratio is correct, especially at high-rpm use. Our selection of premium fuel injectors from Injector Dynamics, Deatschwerks & Fuel Injector Clinic all use top quality components for extended heavy duty use.
