S&B Filters push-in crankcase breather filters are a direct fit on all valve covers that have a 1-1/4" hole. 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.

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.
