850cc Fuel Injectors for Honda / Acura B-Series, D-Series, H-Series

High-Capacity Precision for Honda & Acura Builds The SouthBay 850cc Fuel Injectors are designed for enthusiasts pushing their B16, B18, D16, or H22 engines to the next level. Whether you are building a high-boost turbo setup or switching to E85 for maximum cooling and knock resistance, these injectors deliver the volume and precision required for competitive performance.

Engineered for the Street and the Track Unlike older "hose-style" high-flow injectors, these units feature modern internal geometry that ensures superior atomization. This allows your Honda or Acura to maintain a smooth, stock-like idle and crisp throttle response, even when supporting significantly higher horsepower levels.

Key Features:

• Big-Flow Capacity: 850cc flow rate provides the necessary headroom for high-boost applications and E85 tuning.

• E85 Ready: Constructed with internal components and seals that are fully compatible with ethanol and race fuels.

• Direct Fitment: Designed as a drop-in solution for B-Series, D-Series, and H-Series fuel rails and intake manifolds.

• Strictly Flow Matched: Every set is rigorously tested to ensure perfectly balanced fuel delivery across all four cylinders, protecting your engine during high-load pulls.

• Superior Atomization: Multi-hole nozzle design for improved fuel-air mixing and combustion efficiency.

Vehicle & Engine Compatibility:

• B-Series: B16A, B16B, B17A, B18A/B, B18C, B20B/Z

• D-Series: D15, D16Y, D16Z

• H-Series: H22A, H23A

• Note: Ensure your harness matches; some applications may require EV1 style plug adapters. encluded
