The K&N 63-1127 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Honda TRX450R 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 63-1127 air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory crank case vent hose. 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 a 10 millimeter wrench. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

It's the best air filter. I use this filter (RU-4740) on my Honda TRX450r for many years, great quality. Thanks
Alex, Russia
This product is simply perfect for my new Honda. Easy installation took about fifteen minutes. And I love the improvement from installing this new filter. Subtle but definitely noticeable!
Zach, North Dakota
As a long time K&N customer I use their filters (oil & air) in all my vehicles. When I acquired my new Honda Accord Hybrid installing a K&N air filter was a no-brainer. The car's not complete without the K&N sticker on the air cleaner housing.
