ECS Project - Audi B8 S4 Build List

The supercharged 3.0T power plant up front, six-speed manual transmission between the seats, and Quattro AWD system make the B8.5 S4 a well-rounded and highly capable package right out of the box, but this B8.5 S4 is no ordinary luxury sedan. Our research and development test mule here features everything we currently offer (and some in-progress secret parts) that help transform this super sedan from modest daily into an absolute weapon. Our suspension upgrades, heat exchanger, intake, big bore throttle body, and more help make this S4 the ultimate highway star it deserves to be.
