Ford Racing 47 LB/HR Fuel Injector Set - M-9593-G302

The Ford Racing 47 lb/hr Fuel Injector Set (M-9593-G302) is a complete set of eight high-flow, high-impedance fuel injectors purpose-built for performance Ford applications. Serving as original equipment on the 2007–2010 SVT Mustang, these injectors deliver the flow capacity and precise atomization that serious performance builds demand. Whether you're upgrading a naturally aspirated street engine or supporting forced induction, these Ford Racing parts are engineered to feed your engine reliably at elevated power levels.

Key Features & Benefits

• 47 lb/hr Flow Rate: Delivers meaningfully more fuel than the stock injectors found on lower-output Ford engines, giving tuners the headroom needed to support power upgrades without fuel starvation.
• 6-Hole Spray Pattern: The multi-hole nozzle design promotes finer fuel atomization compared to a single-hole pintle injector, supporting more complete combustion and improved throttle response.
• High-Impedance Design: High-impedance (also called high-resistance) injectors are compatible with a wide range of factory and aftermarket ECUs without requiring a peak-and-hold driver, simplifying integration into most Ford performance applications.
• USCAR Electrical Connector: Features the industry-standard USCAR connector used across a broad range of Ford and domestic performance vehicles, making wiring integration straightforward and eliminating the need for adapter harnesses in most applications.
• OEM-Sourced Performance Pedigree: These injectors were original equipment on the 2007–2010 SVT Mustang, meaning the flow data and calibration characteristics are well-documented and widely supported by professional tuners.
• Designed for Performance Applications: Ford Motorsports engineered these high-flow rate injectors specifically for performance use. They work best when paired with air meters running revised calibrations, ensuring the fueling matches the airflow of a modified intake system.
• Complete Set of 8: You receive all eight injectors in one purchase — no mixing and matching needed for V8 applications.

Fitment

The M-9593-G302 injector set was original equipment on the 2007–2010 Ford Mustang SVT and is designed as a performance upgrade or direct replacement for compatible Ford V8 applications. Because these injectors are intended for performance use and require pairing with appropriately recalibrated air meters, a professional tune is strongly recommended after installation. Always verify fitment against your specific vehicle's fuel rail, connector type, and ECU compatibility before ordering. Note: This product is not legal for street use in California (not CARB compliant).

Frequently Asked Questions

Q: Do I need a tune after installing these injectors?
A: Yes. Ford Motorsports notes that these high-flow injectors work best with air meters running revised calibrations. Installing larger injectors without a corresponding ECU retune will result in an overly rich air/fuel mixture and poor drivability. A professional dyno tune or a pre-configured tune from a reputable Ford tuner is strongly recommended.

Q: What connector type do these injectors use?
A: The M-9593-G302 injectors use a USCAR electrical connector, which is the standard connector found on a wide range of Ford performance vehicles. In most compatible applications, no wiring adapters are required.

Q: Are these injectors high-impedance or low-impedance?
A: These are high-impedance fuel injectors. High-impedance injectors are compatible with most stock and aftermarket Ford ECUs without requiring a specialized peak-and-hold injector driver, which simplifies installation and integration.

Q: Is this product legal for use in California?
A: No. The M-9593-G302 fuel injector set is not CARB legal and is not available for sale or use on street-driven vehicles in California. It is intended for off-road or race use in states where emissions regulations permit.
