7.3 Powerstroke 400CC Evolution Hybrid Injectors 300% Nozzles

Extreme performance competition injectors for 1994-2003 Ford 7.3L Powerstroke diesel engines. Can increase horsepower by up to 700 hp+ with a custom performance chip. Features new nozzles, tungsten-coated plungers and barrels, and a larger 400% oversize nozzle for improved fuel delivery. Hybrid plunger and barrel design moves more fuel. Designed to operate with a stock High-Pressure Oil Pump (HPOP), though it pushes the limits of a 17-degree HPOP. Built and flowed to within 1%. Requires a custom single-shot tuned chip (mandatory for 1999-2003 Powerstrokes to convert from split-shot to single-shot injection). Recommended for competition-level performance only; fuel system and turbo upgrades advised. Core charge required for the set of eight injectors.
