650cc Fuel Injectors for Honda / Acura B-Series, D-Series, H-Series

High-Flow Performance for Honda & Acura Engines When your build outgrows standard fueling, the SouthBay 650cc Fuel Injectors provide the perfect upgrade path for the B16, B18, D16, and H22 platforms. These injectors are designed to deliver the fuel volume necessary for forced induction or aggressive E85 street tunes without sacrificing low-end drivability.

Precision Engineering & Reliability Designed as a direct-fit solution for most B, D, and H-series fuel rails, these injectors feature a modern nozzle design. This ensures a finely atomized spray pattern, leading to more efficient combustion, sharper throttle response, and the stable idle quality that Honda enthusiasts demand.

Key Features:

• Optimized for Performance: 650cc capacity supports higher horsepower targets safely on pump gas or ethanol blends.

• Direct Fitment: Engineered for seamless installation on B-Series, D-Series, and H-Series intake manifolds.

• Flow Matched Perfection: Every set is rigorously tested and matched to ensure balanced fuel delivery across all cylinders, preventing lean spikes.

• Durable Construction: Built to handle the high heat and vibrations of high-revving VTEC and non-VTEC engines alike.

Vehicle & Engine Compatibility:

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

• D-Series: D15, D16Y, D16Z

• H-Series: H22A, H23A

• Note: Check your harness requirements; some applications may require EV1 style plug adapters.
