Our Blowoff Valves are manufactured by Turbosmart of Australia specifically for A&A under a Private Label agreement.
The Race Port is famous for being an amazingly small and light BOV for supercharged competition level engines. Featuring our unique collar design and internal flow structures, it is 50% lighter and 25% smaller than the competition while flowing 330 CFM - making it the highest flowing BOV of its type on the market.
