air cleaners (sock style) - Weber DCOE sidedrafts 40 or 45 Performance Uni-Filter 'sock' type individual air filters have washable foam elements with internal wire support to prevent collapse or intake of the filter element. These mount directly to the velocity stack and will clear the brake booster on a 2002. Available as 40mm or 45mm. Sold in sets of 2 (one set does one Weber sidedraft carb). The Sock-style air filters make more power than any other DCOE air filter we've tried. The base of the filter is a rubber velocity stack for smooth air flow (unlike a flat-face mounted filter). The foam element is supported by an internal spring, this creates a space of "still" unobstructed air from which the velocity stack can pull from (this is the problem with open stacks and snap on mesh screens). Filter Dimensions Overall Length: 4.5" Mounting shoulder: approx. .5" (included in the overall length) Filter diameter: approx. 3 1/8" Price: $49.00   Quantity to Add:   CONTACT US AT BMWSALES@2002AD.COM 1-800-4-2002AD 909-629-1955 outside of the USA COPYRIGHT © 2002 AD, ALL RIGHTS RESERVED.
