NOS NOS has developed our first dedicated DRY nitrous Fogger nozzles specifically designed for use with multi-stage, direct port, Electronic Fuel Injected applications. The single stage nozzle, Fogger SS1, is constructed from Stainless Steel for strength, long life and maximum flow. The Fogger Ti2 and Fogger Ti3 nozzles are constructed from billet Titanium for light weight, durability and maximum nitrous flow required by today's high power, multi-stage applications. NOS has been the leader in innovative, quality nitrous systems and components for over 35 years. These nozzles are the next step in the evolution of Nitrous Oxide power.
