Introduced for the 2016 model year, the 144 horsepower Polaris ProStar Turbo engine was the most powerful side-by-side engine available from the factory on a stock vehicle at the time. The DOHC engine included a number of updates in order to handle the additional power that the turbocharger generated: upgrades to the four stroke motor included forged pistons, high strength connecting rods, sodium filled exhaust valves, and a revised oil distribution system, to name a few. Knock detection and boost control was incorporated into the electronic engine management system. A high flow return style fuel system assures that the engine delivers maximum power at all times, regardless of altitude or ambient temperature.
The K&N air intake system replaces the stock filter and housing for improved performance
And performance it has in spades. The 925 cc turbo engine propelled the RZR XP Turbo EPS from 0-60 in just 5.89 seconds. That’s as fast as a 2016 BMW 330e.
While the RZR XP Turbo EPS and RZR XP 4 Turbo EPS currently have a 13 horsepower advantage on their nearest competitor, you can pretty much expect a power battle to ensue. In fact, Polaris already increased the output of the 2017 ProStar Turbo to 168 horsepower. So why leave yourself at the mercy of a stock engine rating when a K&N performance cold air intake can add over four horsepower simply by installing a bolt on kit?
The issue that’s a common feature among all RZR models through the years is the use of a disposable pleated paper air filter fitted to the OEM air filter box. While a disposable paper air filter is efficient at trapping dirt, they have limitations when it comes to performance and lifetime cost.
The K&N air intake system is fitted with an oversized conical filter that can be washed and reused
To remove this limitation, K&N developed a line of Aircharger performance air intake systems specifically for select RZR models to increase power and torque, and reduce maintenance costs. These air intake systems are an easy to install, bolt-on upgrade which replaces the restrictive original equipment air box and filter.
K&N's 63-1136 for the Polaris Ranger RZR XP Turbo EPS and RZR XP 4 Turbo EPS air intake system features a free-flowing aluminum air intake tube and oversized RU-5064 conical air filter. The intake system also features a custom air box designed to protect the air filter from the elements. This air intake is relatively easy to install usually in 90 minutes or less. The tools needed are a ratchet set, a few wrenches, and flat blade screwdriver.
And while initially a little more expensive than the OEM disposable paper filters, the RU-5064 conical K&N air filters are washable, reusable, and designed to dramatically reduce restriction while offering excellent protection from harmful dirt and contaminants and saving money in the long run. The K&N air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions.
Made of a pre-treated material DryCharger helps keep splashes of water or mud out of your filter
When using in extra dusty or wet conditions, K&N recommends the installation of an RU-5064DK Drycharger air filter wrap. K&N DryChargers are silicone treated, polyester wraps that are made to cover K&N air filters for added peace of mind. The fabric contains uniform micron sized openings that allow high air flow. Yet, due to the DryCharger's silicone treated polyester properties, the amount of dust or water that reaches the air filter is limited.
To clean the filter, you can use a K&N Recharger Kit, like the 99-5000, which will restore air flow efficiency and will bring your K&N oiled cotton air filter back to a like new condition. The included spray bottle of K&N Power Kleen works to dissolve the dirt build up and old filter oil, then it can be washed away with water. After the air filter fully dries, re-oil your air filter with the K&N filter oil squeeze bottle and then reinstall the filter for full performance and protection.
