The K&N 63-1121 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Yamaha YXR700 RHINO FI 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 63-1121 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through a black powder coated aluminum intake tube into the engine’s throttle body for a guaranteed power gain. 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 screwdriver, ratchet set and some wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Customer Feedback


I have a 2001 Yamaha Grizzly 660 4x4. I switched out the stock air filter that was falling apart and replaced with KN filter. Good fit, easy to install and should be a great addition to the quad.

Ride in a very dusty environment during the summer. I thought I would try the wrap with the K&N Filter. This is for my 2001 Yamaha Grizzly 660 4x4. After 3 months of use, the wrap appears to be in good shape and definitely helps with dust issues on the filter. Easy install and cleaning. I think it's a good support product for the filter for this type of riding environment.

Selected for a 2001 Grizzly Yamaha ATV. Could not find one online but KN had one. Fits well, no problems. Will order again.
