Building upon the success of the original model, Polaris has spent the last decade improving and expanding the RZR product line. A common feature among all RZR models, though, is the disposable (and expensive) pleated paper air filter fitted to the OEM air box. While a disposable paper air filter is efficient at trapping dirt up to a point, it leaves a bit to be desired in terms of performance, longevity, and cost.

Fortunately, K&N Engineering has an answer for Polaris RZR owners looking to upgrade the air intake system of their side by side UTV.


K&N developed the 63-1133 Aircharger® performance air intake systems specifically for select 1000 series RZR models to increase power and torque, as well as reduce maintenance costs. This air intake system is an easy to install, bolt-on upgrade which replaces the entire restrictive original equipment air box and filter.


K&N’s Polaris Ranger RZR XP 1000 air intake features a conical air filter and free-flowing aluminum intake tube which deliver air an increased flow of air into the engine’s throttle body for a guaranteed power gain. The intake system also features a custom air box designed to shield the air filters from engine heat. Beyond gains in power the performance air intake kit also improves throttle response and engine sound.

And while initially a little more expensive than the OEM disposable paper filters, the conical K&N air filter is washable and reusable. Further, not only is the filter designed to dramatically reduce intake air restriction but also provides excellent protection from harmful dirt, dust, and contaminants.


K&N Aircharger air intakes for select Polaris RZR models provide increased horsepower and better throttle response. When dyno tested, the Aircharger performance air intake systems increased output by an estimated 3.3 horsepower at the drive wheels.
