Show original supplier description
The DeatschWerks 550cc Fuel Injector Set provides a significant upgrade for enthusiasts looking to enhance the performance of their 1991-2001 Acura Integra and 1992-2000 Honda Civic vehicles equipped with B-series, D-series, or H-series engines. This set includes four meticulously flow-matched injectors, each delivering 550cc/min at 43.5 psi (3 bar). The precise matching, to within 2% variation, ensures consistent fuel delivery and smooth engine operation across the entire RPM range. Constructed from quality OEM cores and featuring modern USCAR connectors, these injectors offer reliable performance and straightforward installation for both OBD-I and OBD-II systems. These 550cc injectors are well-suited for a variety of performance applications, including turbocharged, supercharged, and high-compression engine builds, supporting an estimated 280-320 wheel horsepower on pump gas. The design promotes excellent atomization, leading to cleaner combustion and more efficient fuel delivery, contributing to overall engine performance and drivability. Installation is designed to be direct plug-and-play for the specified applications, with an estimated installation time of 1–2 hours. However, professional installation and proper ECU tuning are strongly recommended to achieve optimal performance and ensure the longevity and reliability of the fuel system. The set includes individual flow reports for each injector and installation instructions.
