S&B Clamp-On Crankcase Breather Vent Filters are designed to work on engines, transmissions as well as oil and gas tanks. These S&B Filters clamp directly to either plastic or metal tubing, and are available with or without a shield. Unshielded filters are available with a chrome or rubber top.

Over 30 years ago S&B Filters started with a simple mission - "to become a manufacturer of the most technically advanced high performance filter on the market." Their commitment to the race community allowed them to develop products that featured incredibly high efficiency ratings and tremendously low air flow restriction.

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.
