These are the reproduction foam filters with the double AC logo and A193 embossing. These are the most correct reproduction foam elements on the market. They have a top and bottom offset as shown in the photos. These foams also come with a set of screens. Screens are replacement that differ slightly from originals. Originals screens can be usedbut may be slightly smaller causing the foam to not fill the base entirely. These foams are constructed from a 36 PPI open cell foam. These can be washed with warm soapy water and re-oil with a recharge kit. It is diffcult to take a photo of these that really shows what they are. Also have the screens and foams in the shopping cart for $44.50/ ea. These are the ones that have been on the market for many years. They only have the markings of the A193 and do not include the "AC" logo.
