HG Motorsport Turbo inlet Audi S4/S5 B9 quattro 354hp (HGIPAUS4S5B9)

The facts of our upgrade intake spigot at a glance: - Flow-optimised - Enables higher peak power as well as improved response The new intake spigot was developed to allow maximum throughput and optimum flow. As the original component is restrictive and also has edges that impede the flow, it is not designed for performance but even creates turbulence and back pressure. By contrast, our upgrade intake spigot was enlarged to the maximum diameter following a 3D scan. Thanks to state-of-the-art flow animations and other computer simulations, this aluminium performance part with CNC flange and handmade outlets was created. This is the only way the air can reach the turbocharger with an optimum, even flow. The results are higher maximum power and improved response.
