Oberg Filters has been protecting race engines for over 20 years. Following the success of the original Oberg 600 Series, Tattle Tale, Daytona and UFO Filters, we are now offering the Billet Series Oberg Filter, in the 400, 600 and 800 sizes. Milled from 6061 T-6 Aircraft Aluminum, this filter offers the same great features with less weight and more strength.  All Oberg filter screens now feature Viton rubber in their compression molded o-ring style surrounds. Now all screens work, whether you're running regular gas, alcohol, methanol or diesel.
