The RIVA Power Cooler is a significantly improved intercooler system for the Sea•Doo 215hp Intercooled Supercharged 4-TEC engine. Delivers an increase of 15-peak horsepower over original intercooler providing arm-wrenching results on the water. Realizing that boost loss was just as important as thermal performance, we designed the Power Cooler with a large, unrestricted core that exhibits minimal pressure loss. Our cooling element is dramatically more efficient than the stock unit with exit temperatures averaging 50°F cooler than stock. This delivers cooler, denser air for increased performance throughout the RPM range. Includes integrated blow-off valve that improves supercharger reliability and performance by relieving unwanted pressure during off-throttle operation. Also reduces supercharger clutch wear and eliminates heat soak in discharge tube. Kits contain all necessary mounting hardware and installation instructions. Requires use of RIVA Rear Exhaust Kit (Part# RS15050).
