Nitrous Express 15600X Extreme Nitrous Purge Valve System 4AN Lightning Solenoid

Vehicle Fitment

• Universal - Compatible with any nitrous oxide system using a 4AN nitrous feed line, with or without a built-in purge port on the N2O solenoid

Fitment Notes

• Designed for 4AN nitrous feed lines - for 6AN feed line applications, see Nitrous Express part 15601X
• For systems already running NX Lightning or Iceman solenoids with built-in purge ports, see Nitrous Express part 15603
• The 4AN manifold installs inline in the nitrous feed line between the bottle and the N2O solenoid - no drilling or fabrication required
• Sold as a complete kit - all required hardware is included

Features

• High-flow NX Lightning solenoid provides faster, more complete purging than the standard solenoid included in the base 15600 kit
• Purges air and vapor from nitrous lines to ensure liquid nitrous is at the solenoid before activation - resulting in a harder, more consistent hit off the line
• Can also be used to bleed bottle pressure down for spot-on nitrous delivery every time the system is activated
• Inline 4AN manifold design works with any system, including those without a purge port on the N2O solenoid
• Push button activation for simple, on-demand purging from the driver seat
• Stainless steel vent tube directs purged nitrous safely out of the engine compartment
• CARB E.O. compliant - legal for use in California

Product Description

The Nitrous Express 15600X is the Extreme version of the popular 4AN nitrous purge valve system - upgraded with a high-flow NX Lightning solenoid for faster, more thorough purging compared to the base 15600 kit. Any time a nitrous system sits idle between runs, air and nitrous vapor can work their way back into the feed line ahead of the N2O solenoid. When the system activates, that vapor has to clear before liquid nitrous reaches the engine - resulting in a softer, inconsistent initial hit. The 15600X eliminates this by allowing the driver to purge the lines of vapor before staging, ensuring liquid nitrous is queued up right at the solenoid for an immediate, full-force activation the moment the system opens.

The inline 4AN manifold design makes the 15600X compatible with virtually any nitrous system - including those that do not have a dedicated purge port on the N2O solenoid - by simply installing the manifold between the nitrous bottle and the solenoid. The included push button allows the driver to initiate a purge from inside the cockpit, and the 7-inch stainless vent tube routes the purged nitrous safely away from the engine bay. The system can also be used as a bottle pressure bleed valve to bring the bottle down to the ideal operating pressure before a run, ensuring consistent shot delivery every pass. CARB compliant and universally compatible, the 15600X is an essential addition to any serious nitrous build.
