K&N 2002-2003 Yamaha YFM660 Grizzly 660 / 2004-2007 & 2009-2013 YFM350R Raptor 350 Replacement Air Filter

K&N YA-6602 High-Flow Air Filter | Yamaha Grizzly 660 & Raptor 350

Upgrade your Yamaha Grizzly 660 or Raptor 350 with the K&N YA-6602 air filter. Designed for high airflow, superior filtration, and increased horsepower in dusty off-road conditions.

The K&N YA-6602 Replacement Air Filter is engineered to provide virtually unrestricted airflow while maintaining critical filtration levels to ensure long engine life. Unlike disposable paper filters, this filter features multiple layers of pleated cotton gauze treated with a special grade of filter oil. This creates a "tackiness" that captures dirt and dust particles while allowing the engine to breathe more freely.

It is a direct "drop-in" replacement for the factory airbox, meaning no permanent modifications or carburetor jetting changes are typically required. Built for the rugged demands of ATV and sport quad riding, it excels in high-altitude and extremely dusty environments, offering a sustainable and performance-oriented alternative to stock foam or paper elements.

Best Uses

1. Off-Road Trail Riding: Ideal for ATVs frequently exposed to dirt, sand, and dust.
2. Performance Upgrades: Best for riders looking for a simple way to boost throttle response and acceleration.
3. High-Altitude Adventures: Provides clean carburetion and better air volume for engines struggling in thinner air.

Features

1. High-Flow Cotton Media: Features layers of woven cotton gauze that provide a large filtration surface area.
2. Washable and Reusable: Can be cleaned and re-oiled using a K&N Recharger kit, eliminating the need for replacement filters.
3. Application-Specific Sealing: Includes a sealing bead and often a sealing grease to ensure an airtight fit in the OEM airbox.
4. Epoxy-Coated Aluminum Mesh: Protects the filter media from debris and structural damage during intense rides.
5. Pre-Oiled Design: Comes ready to install right out of the box for immediate performance gains.

Benefits

1. Increased Horsepower: Higher air volume leads to more efficient combustion and improved engine power.
2. Cost-Effective: Since it lasts the lifetime of your vehicle, it saves money over buying multiple disposable filters.
3. Superior Engine Protection: Designed to meet or exceed OEM filtration standards, keeping harmful contaminants out of the cylinder.
4. Environmentally Friendly: Reduces waste by preventing hundreds of disposable filters from reaching landfills.
