This universal wet nitrous kit from Straightline Performance adds a 25 HP shot to carbureted snowmobiles, ATVs, UTVs, motorcycles, and custom builds running one or two carburetors. Its patented flow-control nozzle regulates nitrous delivery so changing bottle pressure doesn't dictate how much power you get, keeping each hit predictable and repeatable.

The wet-system design supplies supplemental fuel alongside the nitrous, giving carbureted engines the coordinated delivery they need for the intended horsepower increase. Kit selection is based on the number of carburetors, not engine cylinders, and the nitrous bottle is sold separately.
