Jet Ski Exhaust Spray Bar | ACE x Performance

Tune your two-stroke jet ski for more RPM and horsepower. The ACE x Performance Spray Bar installs in your cooling line to adjust water flow into the exhaust pipe, helping you reach optimal pipe temps. This is a popular tuning mod for Kawasaki 550, 650, 750, 800 and Yamaha 701 builds among people looking for budget friendly performance.

Key Features:

• Fits 1/4" hose barb x 1/8" NPT fittings

• Increases RPM, responsiveness, and overall engine performance
• Works with two-stroke jet skis (Kawasaki & Yamaha)
• Tested on real-world builds by ACE x Performance

Tuning Notes:

• Adjust jet size to control water flow to the pipe (jets not included)
• Ideal temp creates a visible sizzle — not steam, smoke, or instant evaporation
• Pipe should not discolor or overheat; use gloved touch as a quick temp check
