BMW Z4 (G29) Carbon Fiber Semi-Closed Cold Air Intake w/ Clear View Window | B58 3.0L Turbo (2019–Present)

Bring out the true spirit of your BMW Z4 (G29) with our Carbon Fiber Semi-Closed Cold Air Intake System, designed for the B58 3.0L turbocharged inline-six.

Built from lightweight carbon fiber, this intake enhances both performance and aesthetics, perfectly complementing the Z4’s sleek, sporty roadster design. The woven carbon finish reflects the car’s motorsport DNA while keeping weight low and heat resistance high — a natural fit for a convertible engineered around agility and style.

At the top, a clear polycarbonate viewing window reveals the filter element inside, blending form and function by giving you a bold, technical look under the hood while making filter checks effortless.

This system is engineered as a semi-closed design, combining the unrestricted breathing of an open-cone intake with the protection of a heat shield. It channels cooler, denser air to the turbos, ensuring consistent performance whether you’re carving corners on a backroad or cruising with the top down.

Performance benefits you’ll feel:

1. Sharper throttle response and reduced turbo lag
2. Quicker turbo spool with a more aggressive induction tone
3. Stronger midrange torque for spirited driving and overtakes
4. Horsepower gains that increase even further with tuning

Beyond the numbers, the intake transforms your Z4’s character — delivering a deeper induction growl, sharper turbo spool sounds, and crisp blow-off acoustics that enhance the car’s already engaging roadster experience.

Paired with high-temp silicone couplers, reinforced clamps, and a precision-fit carbon fiber housing, this intake is built to last under boost, track days, and high-output builds.
