For the BMW X3 M and X4 M equipped with the S58 engine, our goal went beyond developing another high-flow intake system.

We wanted to rethink the entire intake architecture, from airflow routing and component placement to the overall visual balance of the engine bay.

To accommodate two massive 152mm (6-inch) high-flow filters, we had to look beyond the available factory space.

Instead of designing around the limitations, we redesigned the layout to make our vision possible.

01 | A Shorter Path. A More Direct Approach.

Less unnecessary routing. A more direct path to the turbos.

The factory intake configuration features a relatively complex airflow path, leaving room for further optimization.

For the BW-X3M01, we redesigned the intake routing to significantly shorten the airflow path and reduce unnecessary bends and potential restrictions.

The result is a more direct intake configuration engineered to improve airflow delivery.

We also developed dedicated heat shields to help separate the intake area from surrounding engine-bay heat, supporting more favorable intake conditions.

Because better intake engineering isn't just about moving more air.

It's about creating a more efficient path for that air to travel.

02 | Making Room for Dual 6-Inch Filters

When space becomes the limitation, redesign the space.

Fitting two massive 152mm (6-inch) high-flow filters into the tightly packaged S58 engine bay presented a significant engineering challenge.

Rather than compromising on filter size or intake layout, our engineers reconsidered the available space and surrounding component placement.

This led us to relocate the auxiliary coolant reservoir and develop a dedicated relocation bracket specifically for the revised configuration.

Every detail, from reservoir positioning and bracket geometry to surrounding component clearance, was carefully considered to support the new intake architecture.

This wasn't simply about making two larger filters fit.

It was about reengineering the available space to achieve the intake design we envisioned.

03 | Dual 6-Inch Intakes. Designed to Make a Statement.

Performance engineering should be just as impressive to look at as it is functional.

The dual 152mm high-flow filters are more than the centerpiece of the BW-X3M01's airflow architecture.

They define the visual identity of the entire system.

Two massive red filters create an unmistakable presence under the hood, complemented by the redesigned intake pipes and purpose-built heat shields.

Every component was considered in relation to the others, from proportions and positioning to the overall flow of the design.

The goal was to create a cohesive engine bay layout where engineering function and visual impact work together.

From airflow routing to component relocation, every decision serves a purpose.
