Audi Secondary Air Injection Check Valve ensures that fresh air continues to flow in one direction into the exhaust during cold starts to reduce emissions and protect important under hood parts. Audi has built up its reputation on ingenious engineering combining speed, comfort and everyday usability, starting with the development of water-cooled engines and continuing with the famous Quattro all-wheel drive that grips wet or snowy roads. Modern models surround drivers with a Virtual Cockpit digital display, bright matrix headlights for clear night vision and even fully electric e-tron options for clean power. The brand experiments with autonomous ideas while still providing the solid feel and sporty handling that fans recognize as a feature of Audi's commitment to tradition and innovation. Standing behind this range of technology is the reliable Audi Secondary Air Injection Check Valve that helps each gasoline engine meet strict standards. The Secondary Air Injection Check Valve opens immediately when the pump is started so oxygen rushes to the exhaust ports allowing leftover fuel to burn, thereby warming the catalytic converter quickly. As soon as the heat and pressure are reversed, the Secondary Air Injection Check Valve snaps shut, preventing hot gases from roasting hoses or the pump, a simple mechanical action which requires no electronics. By making the catalytic converter turn fast and preventing backflow, this little part contributes to lower hydrocarbon output across the entire lineup, helping every Audi satisfy drivers who want performance that also respects the environment.
