ADA Billet Reed Spacer

These premium billet angled reed spacers from ADA Racing are high-performance upgrades for Yamaha and Kawasaki personal watercraft engines. Precision CNC machined in the USA from USA 6061-T6 aluminum, they feature a 3-degree angle (where applicable) to optimize intake flow by directing air/fuel mixture upward toward the transfer ports. This design increases case volume, improves fuel atomization, enhances mid-to-top-end power, and provides better throttle response—ideal for racing, freestyle, or high-performance builds.The angled design helps prevent reed petal damage at high RPMs, extends reed life (especially with aggressive setups), and is a popular bolt-on mod among PWC enthusiasts. Spacers are anodized or finished for corrosion resistance and durability in marine environments.
