Installed this in my 2009 Yamaha Vino. Perfect fit. Appears the surface area is a lot greater than the factory filter. No issues.

Quick shipping, arrived on time. Ordered three of them for my kids four wheelers. Just installed so too soon to tell how well they work but being reusable is a nice feature.

This filter is a metal screen type just like the stock filter. This type of filter can be cleaned and reinstalled every other oil change or so. The fit is perfect and the build quality seems sufficient.

Cheaper then stock, free shipping and fast. Did not give 5 as I have not had it long enough to see how it holds up.
