The RIVA Engine Breather Upgrade Kits eliminate power-robbing crankcase emissions from your Yamaha engine's air intake. Each kit increases horsepower by removing the engine's requirement to burn relatively non-combustible oil, and in forced induction applications intercooler efficiency is improved by preventing the oil sludge coating that lowers thermal efficiency.
