CNC milled billet intake manifolds for your RS6 C7 or C8 with 4.0L TFSI engine. Maximise the performance of your RS6 with our CNC-milled intake manifolds, specially developed for the RS6 C7 / C8 with 4.0L TFSI engine. Our intake manifolds have been optimised using the latest CFD technology and tested on our dyno to ensure you get the best out of your vehicle. Optimised design! It was particularly important to us not only to enlarge the ducts to enable a higher flow rate. The ducts themselves have also been optimised to optimise flow. The ducts are precisely milled from a billet block using our CNC to achieve the best possible result. More efficient combustion! Through extensive test runs on our test bench, we have optimised the intake manifold in such a way that the pressure loss in the intake system is significantly reduced. Each duct is precisely machined to maximise the air flow to the cylinders. This allows us to improve combustion and optimise the torque curve. With our upgrade intake manifold , you not only get better acceleration, but also improved overall driving behaviour. Simply more dynamics and driving pleasure for your RS6. Jets not included.
