Full Flow Oil Filter System

The Shasta Design full flow oil filter system has 2 distinct advantages over the stock 356.912 oil filter system. Number one, of course, is that it filters all of the oil all of the time, keeping it much cleaner that the factory partial system, which filters about 15 to 20% at any one time. Number two is that the oil runs much cooler, about 25 to 30° below the stock system. One does not need to be a rocket scientist to realize that if the oil is clean and cool, the engine life will be greatly extended.
