The K&N 63-1120 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Polaris Ranger RZR models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-1120 air intake comes with a K&N XStream Top air filter designed for higher air flow and durability. A heat shield installs into the previous air box space that directs air through a black powder coated aluminum intake tube into the engine’s throttle body for a guaranteed power gain. The heat shield accommodates the factory crank case vent hose with a supplied CCV filter. The oversized cone shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a couple of screwdrivers, a ratchet set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N air filters are simply the best air filters that I know of. I learned the K&N name in the early 70's when I started working on a friends dirt track racing bikes. In the pits there were only two filters used and K&N was by far the dominate brand and the ones that we used. I presently have K&N filters on two pickups, a 1999 and a 2015 Chevrolet, two ATV's a Honda and Polaris and a 1977 Yamaha that I restored. I would put one on my lawn mower if you made them. This filter was for the 2015 Chevrolet. The original filter was still snow white when it got tossed for the K&N.

I started racing motorcycles in the early 70's and as a greenhorn learned about K&N filters in the pits. I have K&N air filters on everything but my lawnmower. A restored 1977 RD-400 Yamaha, a 2007 Hummer, a 1999 Chevy p.u., a 1987 Honda ATV, and now my 2004 Polaris. They are the only air filters that I will pay money for.
