Personally i have been using such performance filter and have noted a decrease in low end performance. However the high end do seem to be smoother with it. 

I personally don't recommend smaller cc. vehicle to have this upgrade as it totally defeats the purpose of having a small engine which is to be responsive. And lastly, our MB Original filter is already superior in quality. Cheers!

Hi, has been using the filter on my w204, the k&n filter can be quite dirty after short while, usually I will take it out every few months and just do simple knock the filter on floor, u will find lots of black dirt come out...for normal paper filter, I don’t get this kind of dirt.. don’t know good or bad??

Usually after the simple dirt removal, the car is more lively...

Why not wash it? just buy the K&N wash kit. Spray the detergent on the filter, let it soak for 5 mins. then rinse off. You will be more amazed at the amount of dirt trapped in it. Air Dry it for 24 hrs or use a hair dryer (don't spray dry with air gun at workshop...it will damage the filter) Then re-oil it sparingly....the filter is as good as new.

I use the K&N wash kit for my BMC filters. Same thing
