Why our nitrous system is better 

 

A complete “Direct Port” nitrous system.  Everything is included in this kit for a safe, proper installation. 

 

Adjustable from 50-200 horsepower.  Safe enough for stock engines, powerful enough for racing use. 

 

Uses one injector nozzle per cylinder.  Gives perfect nitrous and fuel distribution. 

 

Features easy to install, pre-made nozzle flex-lines.  No hours wasted on cutting and bending distribution 

hard-lines. 

 

Dual-stage jet technology uses one jet in the distribution block and one jet in the injector nozzle.  Offers 

much finer tuning adjustments as well as easy HP level changes.
