The DeatschWerks 850cc Side Feed Injectors are a high-performance fuel system upgrade designed to provide increased fuel flow for modified engines. This matched set of four injectors offers a significant increase in fuel delivery capacity. Key features include high impedance coils, ensuring compatibility with your vehicle's factory ECU and injector driver. These injectors are also ethanol and methanol compatible, offering flexibility for various fuel types and blends. Each set is meticulously flow-matched to within 1-2% to ensure consistent fuel delivery across all cylinders. A detailed flow report is included with every set, providing precise performance data. DeatschWerks constructs these injectors using either reconditioned OEM cores or entirely new units, all subjected to a rigorous 40-point data inspection before shipment for guaranteed quality and performance. However, it is crucial to verify fitment with your specific vehicle's year and model. This specific part number, DWK02J-00-0850-4, is designed for Subaru STI EJ25 models from 2004-2006 and Legacy GT EJ25 models from 2005-2006. It is explicitly stated that these injectors *DO NOT FIT OTHER YEARS*. Please ensure your vehicle falls within the specified fitment range to avoid compatibility issues.
