Show original supplier description
The Grams Performance GRPG2-0550-0500 is a set of four high-performance fuel injectors engineered for Honda and Acura vehicles equipped with B, D, F, and H-series engines, with the specific exclusion of the D17 engine. These injectors offer a flow rate of 550cc per minute (equivalent to 50 lbs./hr) and are built to accommodate various fuel types, including gasoline, methanol, and ethanol, making them suitable for modified performance applications. They feature a high-impedance design and utilize Bosch EV14 technology with an EV14 pigtail, though a wire splice may be required for installation depending on the specific vehicle application. The set is a direct replacement for factory injectors, simplifying the upgrade process for a broad spectrum of older Honda and Acura models. This fuel injector set is compatible with a comprehensive list of Honda and Acura vehicles. Fitment includes various trims and years of the Acura Integra (GS, GS-R, LS, RS, Type R), Honda Civic (CX, DX, EX, HX, LX, RT 4WD, Si, VX), Civic del Sol, CRX, Prelude, S2000, Wagovan, and Accord models. It is crucial to confirm specific vehicle compatibility based on the provided fitment list, as the D17 engine is explicitly excluded.
