USP Motorsports Releases DSG Cool Flow Aluminum Filter Housing Share Comments Your DSG transmission is equipped with a filter inside a fragile plastic housing. Unfortunately the plastic filter housing becomes brittle over time and often cracks during filter changes which are performed every 40,000 miles. Constructed of billet aluminum, the USP Cool Flow housing is far stronger than the factory plastic housing. Not only is the Cool Flow housing stronger, but it also incorporates cooling fins to cool the DSG fluid as it passes through the filter and housing. Installation is straight forward and requires no special tools. This is a must have for every DSG owner. Features: – CNC’d Billet Aluminum – Hard anodized clear for longevity – Uses OEM filter and o-ring – Limited Lifetime warranty Visit USP Motorsports website HERE for more information.
