Nitrous Express Wet Nitrous Kits

Proton Nitrous Systems

Nitrous Express has done it again! Imagine having both Nitrous and fuel solenoids in a common housing. The new PROTON solenoid assembly makes finding a good location for the solenoids a whole lot easier.

The new entry level PROTON system packs both solenoids into a small billet aluminum housing , measuring only 4.125” wide x 2.250” tall x 1.50” deep, it takes very little room.

Complete Proton systems are available for all single, twin, triple and four cylinder powersports vehicles.

Piranha Nozzle Nitrous Systems

The NX Piranha Nozzle systems are designed for all applications without an existing fuel system for the nitrous kit. These systems come complete with fuel pump, 2.5lb bottle, stainless steel bottle bracket, nitrous and fuel lines, relay and wiring harness, WOT activation switch and Jetting for the hp listed below. The Hayabusa system has 2.0lb bottle to fit in the small compartment of the Hayabusa. Also has a longer N2O feedline to help with mounting the bottle. The polished bottle Harley applications include the necessary mounting brackets to mount the bottles on your fork. (Specify downtube size!). All kits can be customized with different size bottles upon request.
