Nitrous Express - Motorcycle 4 Cyl Dry Nitrous Bottle
This is what happens when you ask the mad scientists at NX to address the issues with mounting and plumbing a dry direct port style configuration into any Sportbike air lid! Jetting is simplified allowing a single jet to control the Nitrous flow for all the nozzles, not the traditional 4 jets that are normally required to change power levels. The new distribution block design is extremely easy to mount, using bulkhead style distribution block allowing the installer to make custom length nozzle lines on site to simplify difficult installs. This system is capable of 200 WHP* and the solenoids are designed to be used with the NX Maximizer Progressive controller for the ultimate nitrous experience! System Includes.078 Nitrous Solenoid,
