Obviously, you bought your S4 because you understood you would be getting long-lasting quality and dependability both rolled up into one automobile. Audi automobile owners have grown accustomed to a certain level of sporty handling when driving their S4 around town. Your Audi dealership isn't the only place to find the best replacement parts for your S4. It's not a regular occurrence that you realize that you have to buy a replacement PCV Valve to fix your vehicle.
Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on how well you maintain your engine and exhaust parts. Your Audi S4 engine, as great as it is, isn't 100% efficient and it needs a system to control positive crankcase ventilation with a working PCV valve. Almost always mounted above your cylinder head in the valve cover, your Audi S4 PCV valve is a one-way valve that receives the escaping exhaust blow-by from the crankcase and routes it into the intake. Before the positive crankcase ventilation valve, all blow-by was simply vented through a small filter element in the valve cover. This is a much cleaner method.
