Grams Performance is proud to offer the most innovative high-performance fuel injectors for todayâs performance vehicles. Premium materials, advanced manufacturing techniques, and stringent quality control procedures make Grams Performance the leader in high-performance fuel injectors.
Each Grams Performance B/K-Series Fuel Injector Kit includes four Grams Performance 550cc/min, 750cc/min, or 1000cc/min Fuel Injectors and four Pigtail Adapter Harnesses for easy adaptation onto any Honda B/K-series engine (B-series also include billet top hats). An engineâs fuel injectors perform a vital role in the accurate metering and atomisation of fuel. Grams Performance accomplishes this with its high-impedance Bosch Motorsports EV14 fuel injectors that are modified for high-performance use.
Each injector is individually balanced, flow tested, and dynamically matched for characterisation within one percent of one another. To ensure leak-free operation and optimal performance, each injector is then pressure tested up to 220 psi. The results are unmatched cylinder-to-cylinder consistency, even at low pulse widths, as well as optimal idle quality, response, and performance. Grams Performance Fuel Injectorsâ ultra-fast and precise solenoids feature a linear response curve across a wide range of operating conditions and can accurately meter fuel even at the highest pressures and shortest pulse widths.
The EV14 injectorâs superior ball/pintle valves combined with Grams Performanceâs precision-modified nozzles allow for consistent performance up to 118 psi, making them suitable for a wide range of applications, yet without exhibiting any of the high-pressure problems often associated with other injectors. The optimised spray pattern also helps improve mixture preparation as well as atomisation.
Grams Performance injectors are cold-cut with diamond grinders in less than three seconds for high precision without âpre-seating.â Abrasive cutting creates heat, which leads to poor spray patterns and the need for competitors to pre-seat their injectors to reduce distortion. Each injector is also fitted with high-quality Viton O-rings that are resistant to extreme temperatures and harmful oils found in some fuels.
Each injector set includes dead time compensation values to help ensure consistent air/fuel ratios and optimal performance when tuning. Grams Performance Fuel Injectors are carefully tested and matched in controlled laboratory environments using state-of-the-art equipment and are subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions.
- High-impedance design (no resistor box required).
- Cold-machined tips for high-precision operation.
- Ultra-fast solenoids for precise fuel metering.
- Linear response across wide range of operating conditions.
- All injectors balanced, blueprinted, and matched within one percent.
- Compatible with all known fuels including gasoline, methanol, and ethanol.
- Unmatched cylinder-to-cylinder consistency and optimal idle quality.

Choose from 550cc/min, 750cc/min or 1000cc/min 2000cc/min. Ideal for all B-series and K-series Engines engines.
550cc - £328.61
750cc - £413.35
1000cc - £413.35
2000cc - TBC
