Hi,

There are two types of Cabin Filters, one a straight paper filter (24.50), the other permeated with Activated Charcoal. The PN# is 996 572 219 01 (Activated Charcoal - $41.00). They differ in price by about $20.

They both filter the Air equally well, but the Charcoal Filter will filter out some odors, but not all. Unless you're driving about 99% of the time with the Top Up or the Hardtop On, the Activated Charcoal Filter is a waste of money.

With the Cabin Open, the Charcoal Filter is just a waste of money as no benefit is derived from it over the straight pleated paper filter. I use only the paper filter and it works just as well. Hope this helps...

Happy Motoring!... Jim'99
