Hi all! Great site, I'm a new Benz owner with a just purchased 2009 black e350 4 matic. My garage includes a 2004 ZO6 Corvette, black and a 2010 black lifted Toyota Tundra running 35 inch tires. I tried to upload photos but I believe they were too big. Will try again. I promise to research my questions before I ask for help, but, I do have one that I cannot find an answer too!? Can someone advise on me how to replace the twin air filters? I have 2 new K&N's to install and I cannot figure out how get the air box open!? Thanks in advance! I have MUCH to learn about this car and will be reading many of your informative threads here!
