Review on Mann-Filter CUK 3139 Activated Charcoal Cabin Air Filter by Brandon Wynen

Easy installation. Bought because a thief gave me a price of $180 to replace 2 micro filters in my BMW. Not sure what exactly you're asking for? :/ Installation is very easy. It took me 20 minutes to remove, clean and replace the old micro filter. I would say that even though the micro filter I removed was an OEM BMW and you could tell from the outside the filter was plastic rather than the cardboard used in this product. I'm not saying the product is bad, but it doesn't look like an OEM. Love the fact that it's activated charcoal which you can't get if it's stolen.
