Description
Description
Industrial Injection Stage 5 400cc race injector with internal oil modifications for 1999.5-2003 Ford F-Series and Excursion 7.3L Powerstroke trucks. A maximum-fuel HEUI injector built for serious horsepower builds — drag race, sled pull, and dyno work where the stock injector won't keep up.
The internal oil mods improve plunger response and lubrication margin at the extreme duty cycles a Stage 5 sees in competition. Each injector is fully calibrated and flow-tested on the IIS bench so cylinder-to-cylinder delivery stays balanced even at the high end of the fuel map.
