S&B Filters screw-in crankcase breather filters are engineered to screw directly into the threaded valve cover on your Ford's engine. Designed to work on engines, transmissions as well as oil and gas tanks, these filters are the perfect solution for your crankcase ventilation needs. 2-1/2" tall breather filters are available with a shield or without a shield. A low profile, un-shielded version that is just 1-3/4" tall is also available.

S&B busted knuckles with the best engine builders of the day to deliver a product that supplied what they were craving - a filter that delivered performance advantages without sacrificing engine protection. They succeeded by keeping their production capabilities on the front-edge of technology, and never, ever wavering from their goal of producing a high performance air filter that tests better than any other manufacturer. And even today they are pushing the other manufacturers to test to their standards.
