"Received the K&N filters for my SL500k today. Quality product just as advertised. Fit the airbox perfectly. Noticeable performance increase over the new stock paper filter I decided to replace it with. When you stomp on the accelerator you can tell the engine is drawing more air in over the stock paper filter." —Kurt W from Keller, TX bought a K&N Air Filters for a 1997 Mercedes-Benz SL-Class.
