The NX Lightning 375 is the largest progressable solenoid on the planet! Engineered with only one internal 90 degree turn in the nitrous flow path, a true .375 orifice and its ability to be electronically progressed makes this solenoid a must have for any serious ompetitor. The 375 minimizes nitrous boiling and delivers a denser form of liquid nitrous to the system resulting in a cleaner running and easier to tune nitrous system. The 375 is engineered to accept up to a 10AN inlet fitting and a 6AN outlet fitting and has an integral purge port allowing clean pure nitrous to be drawn across the inlet orifice to insure a repeatable solenoid reaction time.
