The K&N YA-7007 is a high-flow, panel-style replacement air filter for the Yamaha YFM700F Grizzly FI Auto 4x4. It uses pleated cotton media with multiple layers of woven cotton gauze, and the manufacturer says it is designed to increase horsepower and acceleration. No fuel management modifications are required to obtain the increased performance.
The main reason to choose this filter over a disposable element is longevity. The manufacturer describes the filter as washable and reusable, so a rider can clean, dry, and re-oil the same element instead of buying a new one at every service. Generally, no jet changes are required with just a K&N filter element. That makes it a practical upgrade for a stock-jetted Grizzly, and the manufacturer says it is well suited to extended use in dirty and dusty off-road riding.

The manufacturer states that generally no jet changes are required with just the K&N element, and that no fuel management modifications are needed to gain the increased performance.
The manufacturer describes K&N replacement air filters as washable and reusable, so the same element can be serviced repeatedly rather than replaced.
The manufacturer's Yamaha application page lists 2007 and 2008 YFM700F Grizzly FI Auto 4x4 applications, while the product title reads 07-09. Other sources list wider year ranges, so confirm the correct year range with the manufacturer before ordering.
This is a filter swap rather than a modification. The manufacturer designed the element to fit directly into the OEM air box, with an application-specific sealing bead for a precise fit. Open the air box, remove the stock element, wipe out any dirt in the housing, and seat the K&N element so the sealing bead sits fully against the box before closing the lid. A poor seal lets unfiltered air bypass the media, so check the fit carefully. The manufacturer publishes an installation instruction sheet for this part, and owners should follow it for the exact procedure.
