650cc Fuel Injectors for Subaru STI 2.0L Conversion - Bosch EV14 High Performance Set

Ultimate Fueling for High-Horsepower Subaru Builds

The SouthBay 1650cc injector set is designed for the most demanding Subaru 2.0L EJ-series engines. Utilizing genuine Bosch EV14 technology with specialized stainless steel internal components, these injectors provide the massive flow volume required for high-boost applications without the reliability issues common in lesser injectors. They offer exceptional low-pulse-width control, ensuring your car maintains a stable idle despite the enormous flow capacity.

Built for E85 and Race Fuels

Designed with modern fuel chemistry in mind, these injectors are completely resistant to the corrosive nature of Ethanol and E85. Every set is dynamically flow-matched within 1% to ensure perfect cylinder-to-cylinder distribution, protecting your engine during high-load pulls.

Plug-and-Play Integration

Installation is simplified with the included Subaru-specific plug-and-play wiring adapters. These allow you to connect directly to your factory harness, maintaining a clean engine bay and ensuring a secure electrical connection without any cutting or soldering.
