Outstanding. Have one in all 3 of my vehicles.

My car usually likes its shift points in mid rpms, so I thought it would gain some power with a K&N filter. Now it seems to run smoother and it accelerates slightly better. I like the new design of the rubber seal. It is much more snug than stock filter brands and the material prevents seepage. Great product and will buy it for future cars to own.

Good quality, but a bit difficult to fit in the cabinet as the rubber edge is a bit thicker than the original part, which made very hard to clip the cover back onto. You have to press hard to try to close the cabinet.

Product itself seems well made. Good Quality and well packaged in the box. Installation was very difficult though: The K&N Filter is about 3mm thicker (height-wise) than the stock filter, so it is very difficult to fit into the housing that holds it together. Once I placed it, I had to use a LOT of force to get the clips together to attach the airbox. If they could make it that 3mm thinner (only the rubber boarder bit), it would be straight forward and make it a 5 Star Product.
