Presenting the perfect addition to our X5M, XM intake system to optimize the flow path all the way to the turbos. Our carbon inlets have a larger volume than the stock inlets by maintaining a larger diameter all the way to the turbos. The stock inlets narrow down immediately after the connection to the intake which creates a restriction especially at higher boost levels. We have alleviated this restriction and also designed the curvature to be as smooth as possible allowing the turbos to function with reduced resistance. Made from prepreg carbon fiber with CNC machined flanges, the inlets also provide an aesthetic improvement to the engine bay.

Benefits of the inlets are apparent with tuned vehicles where the boost pressure is higher and therefore the flow demand form the turbos is greater. This is where the larger volume of the carbon inlets help provide that extra flow.

The performance gains are produced from providing the turbos with a less resistive flow path which allows them to reach peak boost sooner in the RPM range. When comparing to the stock inlets the differences are clear to see. Where the stock tubes narrow down immediately after the connection to the intakes, our tubes maintain a larger diameter and the reduction to the stock turbos is achieved with an internal radius on the machined flanges. This allows for larger volume whilst maintaining a smooth flow path. One of the drawbacks of the oversized inlets was the more aggressive reduction in size to match the stock turbos which created some flow constraints.
