RIVA ENGINE BREATHER UPGRADE KIT, 2012-21 YAMAHA 1.8L

Easy to install Engine Breather Upgrade Kit eliminates power-robbing crankcase emissions from your engine's air intake. Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. In forced induction applications intercooler efficiency is improved by preventing the oil sludge coating that lowers thermal efficiency. Kit includes K&N filter along with all necessary hardware & detailed installation instructions.
