Polaris 2014-2021 XP, XPT and XPT-S engine crank case breather kit. RZR XP motors are notorious for excessive crank case pressure, the factory breather system recirculates crank case blow by back into the intake system from a breather box on the lower front side of the engine case. The main problem with this design is how close the breather box is to the oil pan allowing oil to be carried out with the crankcase blow by and then put into your intake charge and burned. XPT models are known for rod bearing failures due a number of issues, one being low on oil. XPT engines hold just over 3qts of oil, and can suck over a quart of oil through the stock breather system in a very short period of time depending on driving and terrain. TPR Industry’s breather system eliminates oil consumption and loss of oil being stored in a breather tank like most kits are designed. Our multi chambered tank is designed to catch oil and drain it back to crankcase through a massive -16 AN line and a redesigned billet breather box. While still catching fuel and water vapor in a separate chamber that can be drained. We’ve also incorporated a -10 valve cover breather cap that replaces your oil fill cap (that will fit under your stock bed cover) allowing your valve cover to also vent to the breather tank. By adding the valve cover breather this cuts down on the volume of blow by coming from the front lower pick up point hence not being able to carry as much oil with it. Some XP non turbo models may require clutch intake hose modifications. All XPT & XPT-S models will require no modifications for installation. Kit will include all necessary parts and hardware for installation, including ARP 12pt stainless bolts. Installation time will be approximately 2 hours.
