Massive Flow with Precision Control
The SouthBay 1000cc fuel injector kit is the benchmark for high-performance Subaru 2.5L builds. Utilizing the industry-leading Bosch EV14 platform, these injectors offer the perfect balance of volume and atomization. Whether you are running high-octane pump gas or making the switch to E85, these injectors provide the overhead needed to maintain safe air-fuel ratios under extreme boost pressures.
Engineered for the EJ255 & EJ257
Every set is dynamically flow-matched within 1% to ensure perfect cylinder-to-cylinder synchronization—essential for preventing lean conditions in the EJ engine. These are high-impedance injectors, making them a direct plug-and-play solution for your factory Subaru ECU without requiring a resistor box.
