This manifold is crafted to improve both horsepower and torque, offering a noticeable performance gain for compatible vehicles. The design features port work, internal re-engineered shaping, and a better-flowing flap. This product is compatible with the Audi S4 models in the B6 chassis (2003-2005) and B7 chassis (2005.5-2009), as well as the C5 chassis allroad (2001-2005).
