I've since driven through dusty roads and city driving for about 5k KM on the filter. Took it out and checked and to my surprise, it seals perfectly well compared to stock factory air filters. Stock factory air filters do leak a bit on the sides and lets a bit of dirt into the inlet but K&N does not. The clean side is totally spotless and so is the inlet pipe. It may look much more porous, but due to its design, it works better. I am going to report back much later on my experiences. Happy user. Jason.

I love these filters, this was the third one I have purchased, now all my vehicles are K&N equipped. I will never buy any other!

Fits way better than original air filter and my SUV drives way better than before. Totally liking it. I should have got it earlier. Thanks K&N.
