Genuine Audi S4 Diverter Valve

The Audi S4 Diverter Valve not only maintains smooth turbo boost and ensures the protection of vital parts, but it also offers drivers quicker throttle response and confidence in the long term. This small Audi device bypasses the harmful effect of compressor surge by diverting unnecessary pressurized air to the intake immediately after the throttle shuts, causing the turbo to continue rotating freely and eliminating the loud hiss associated with atmosphere venting valves. It uses simple spring tension and manifold vacuum rather than complex electronics as the basis of its piston style, giving it a reputation for rock solid reliability over several Audi generations. Being installed in the earlier twin turbo V6 models, the high-revving V8, or the modern 3.0-liter supercharged systems, the valve will not make any changes to the boost levels or the fuel ratios, and will maintain factory boost on all S4 badge cars. It is versatile because the Secondary Air Injection circuit has a second Diverter Valve which will redirect fresh air to the Secondary Air Injection during deceleration to prevent backfires and eliminate cold-start emissions, all in the name of efficiency and safety. Owners also enjoy that this single part will allow clean exhaust, improved fuel mileage and power that is predictable without the need to service it often. Since it does not leak the fuel-laden air, but rather recirculates it, the catalytic converters remain healthier and the computer does not need to seek out rich mixtures. The Diverter Valve permits the refined nature required of an Audi sports sedan to be seen, compared to the noisier solutions. It is also a resounding success in the Audi performance market and a true example of how a simple mechanical answer can yield high-quality results in some cases. Since the original quattro sedans of the early 1990s, each S4 is more than a winner when its Diverter Valve functions properly with a sharp response, allowing the turbo system to give it factory boost curves that seem as smooth as the rest of the Audi driving experience.
