Tuning 1300X 1340cc Fuel Injectors

The Cobb Tuning 1300X Fuel Injectors are a high-performance upgrade designed to provide ample fuel for modified Subaru WRX and STI engines. Developed in collaboration with Injector Dynamics, these top-feed injectors offer a 1340cc/min nominal flow rate, ensuring sufficient fuel delivery for significant power increases. Constructed with all stainless steel internals, these injectors are exceptionally durable and resistant to the corrosive nature of alternative fuels like ethanol. This makes them an ideal choice for enthusiasts who frequently switch between gasoline and ethanol blends. The matched sets ensure a dynamic flow rate variance of within 1%, contributing to smooth engine operation and precise tuning. Designed to work seamlessly with the stock fuel rail, the 1300X injectors come as a set of four, including new injector harness adapters. Cobb Tuning provides essential data for tuning these injectors with their Accesstuner software, simplifying the calibration process for tuners. The injectors utilize a 14mm bottom O-ring for secure fitment.
