High quailty, environment friendly product. If your engine is feeling groggy and sick, this is just what the doctor ordered. Quit wasting money on worthless paper filters, and do yourself, and your vehicle, a favor by going with K&N.

Love this product i have them on all my vehicles and my off road toys. I like that they only need cleaned every 50,000 miles under normal conditions also the added performance is nice and that they filter the really well

So far I am noticing no real appreciable differences. Gas mileage has not improved. No noticeable bump in performance. But I do believe the engine is breathing better. I found no credibility to some of the reports that said cabin noise increased.

Filter arrived pre-oiled and ready to install. The quality of the filter is noticeably better than the disposable alternatives. FYI - The way the filter sits in the filter box for the STS is a little concerning, since the rubber edge of the filter is exposed on the bottom, but not the top. I removed the box from the car to do the replacement. It would be hard to get the filter in correctly, otherwise.
