These ZEX Pro Street diesel nitrous systems are specifically engineered to take advantage of the increased fuel delivery, oversized injectors, and high boost capability of today's high performance EFI diesel engines. They feature a huge nitrous solenoid and larger -4 AN nozzle feed line, providing you with the high-flow hardware and jets to give you 50-300 additional horsepower. In order to properly time and control the systems, a boost pressure switch is included and used in tandem with an electronic TPS switch for reliable system activation. By more thoroughly burning the increased volume of diesel entering the engine, the ZEX Pro Street diesel nitrous systems increase power, reduce exhaust gas temperatures, cool the inlet air charge, and drop your quarter-mile times.
