Review on Mann-Filter CUK 3139 Activated Charcoal Cabin Air Filter by Charles Julian

2004 BMW 530i. It's as simple as everyone says here. And yes, order 2. A few notes on some minor things: the dimensions currently listed in the specs section are incorrect, closer to 12.5" x 6.75" (NOT 9") x 1.2" ". Small thing, but 3 inches wider bothered me a bit, but the picture wasn't in that aspect ratio (it would look more like a square), so I took a chance. It's also worth noting that there is a hood close sensor on the passenger side filter cover that needs to be disabled in order to remove it to change the filter. Not so hot what's up. I ended up going through the reset procedure mentioned in another review and everything works fine, although mine has been reset to 70000 miles which is more in line with my experience. This is not a 15,000 mile replacement item.
