This universal wet nitrous kit from Straightline Performance adds 25 horsepower to carbureted powersports engines running one or two carburetors, whether that's a snowmobile, ATV, side-by-side, motorcycle, or custom build. Its patented flow-control nozzle regulates nitrous delivery so changing bottle pressure doesn't dictate how much power you get, keeping each activation consistent and repeatable.

The wet-system design supplies nitrous and supplemental fuel together, which matters on carbureted engines where extra fueling is essential. The kit ships with the nozzle system, nitrous and fuel delivery components, plumbing, activation controls, hardware, and universal installation instructions with baseline setup guidance; the nitrous bottle is sold separately.
