Grams Performance G2-0550-1001 Fuel Injector - Kit

The Grams Performance G2-0550-1001 is a precision-engineered fuel injector kit that includes four high-performance injectors designed for demanding applications. Built on the proven Bosch Motorsports EV14 platform, these 550cc injectors are individually balanced, flow tested, and dynamically matched to within one percent of each other, ensuring exceptional cylinder-to-cylinder consistency and optimal engine performance.

Advanced Engineering and Quality Control:

Each injector undergoes rigorous testing protocols including individual flow characterization and pressure testing up to 220 psi to guarantee leak-free operation. The high-impedance design eliminates the need for resistor boxes, while ultra-fast solenoids deliver precise fuel metering with a linear response curve across a wide range of operating conditions. These injectors maintain accuracy even at high fuel pressures and extremely short pulse widths, making them ideal for both street and track applications.

Precision Manufacturing:

Grams Performance utilizes cold-cutting with diamond grinders to shape injector nozzles in under three seconds, avoiding the heat distortion and poor spray patterns associated with abrasive cutting methods. The superior ball and pintle valve design, combined with precision-modified nozzles, delivers consistent performance up to 118 psi with an optimized spray pattern that improves fuel atomization and mixture preparation. High-quality Viton O-rings provide resistance to extreme temperatures and corrosive elements in various fuel types.

Key Features:

• High-impedance design eliminates need for resistor box
• Cold-machined diamond-ground tips for precision spray patterns
• Ultra-fast solenoids for accurate fuel metering
• Linear response across wide operating conditions
• All injectors balanced and matched within one percent
• Compatible with gasoline, methanol, and ethanol fuels
• Includes dead time compensation values for tuning
• Pressure tested to 220 psi for leak-free operation
• Optimal idle quality and throttle response

Each set includes dead time compensation values to ensure consistent air/fuel ratios during tuning. These injectors are tested in controlled laboratory environments and validated through extensive dyno, street, and track testing to deliver reliable performance under the most extreme conditions.
