Show original supplier description
The Ford Performance M-9593-LU47 is a set of eight high-flow fuel injectors, each delivering 47 lb-hr. These injectors feature an EV6 body style and a USCAR connector, and are a long style (60 mm). The dual cone spray pattern is specifically engineered for the 5.0 L 4V cylinder head, aiming to optimize drivability, emissions, and fuel economy. These injectors are recommended for supercharged applications up to 600 rwhp and naturally aspirated E85 setups. They are also suitable for Cobra Jet intake swaps and 2018+ intake manifold swaps. The calibration summary indicates a flow rate of 47 lbs/hr at a delta pressure of 39.15 psi, with an impedance rating of 11-18 ohms. Additional notes confirm fitment for Mustang and F-150 5.0 L variants. It is important to note that these injectors are intended FOR CLOSED COURSE COMPETITION USE ONLY and are NOT INTENDED FOR STREET USE. The sale, use, or installation of this product may be illegal nationwide under the Federal Clean Air Act.
