There seems to be a rush to get these Mann filters from Advance Auto, but I'm curious why there're better than the Mercedes OEM filters listed at some dealers on-line for $11.25 (no tax, free shipping for orders >$50 or so), for instance
OE Discount Parts
Are the Mercedes OEM filters paper, and is that why the Advance Auto filters are better?
