This siphon break is installed in place of the stock breather hose to prevent oil from flowing up the stock crankcase breather hose which; subsequently, flows into the center console. This inevitably happens anytime the Rhinos are ran at high RPM's and high crankcase pressure. If you're getting oil on your motor after running hard, you need this siphon brake.
This product also adds added crankcase pressure which helps for those of you looking to build your motor.
