This universal wet nitrous system from Straightline Performance adds 25 horsepower to fuel-injected powersports engines with one or two throttle bodies, whether that's a snowmobile, ATV, UTV, or motorcycle. Its patented flow-control nozzle regulates nitrous delivery to keep output consistent as bottle pressure changes, and the wet design supplies supplemental fuel alongside the nitrous for a coordinated power increase. The kit includes 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, and professional installation and calibration are recommended.
