Hi guys, I made myself a little smart. At the SLK 350 M272 there was a sports air filter box. This is from the size equal to the M273. There are probably colleagues who have tested the already in the CLK 500 etc. and it really has to bring a nice intake noise. Does someone from you already use it? I would be interested to hear if the intake noise even with the 500 with sports exhaust???! The divider. is A2730901201 Gruss Cross
