It´s a very important component, which is mounted right between the turbocharger and the air intake. Only as far as the entire intake system is optimized, the turbocharger and the engine are able to show their full capability. This product was developed to maximize and optimize the flow rate of air intakes.

Because the OEM part is designed restrictive and has additionally (regarding to the flow) a few disadvantageous edges on the inside. It´s not designed for maximum performance, because it also generates turbulences and pressure peaks. However, after 3D scanning and testing, our High-Flow Inlet Pipe was increased to the maximum diameter.

Thanks to the latest technology of flow animations and generally all other computer simulations, we were able to develop this performance part, made of aluminum, provided with a CNC flange and hand made connections.

This is the only way to perfect the air flow between air intake and turbocharger of your.
The results are a power improvement, earlier response and a increased durability of the turbocharger.
