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

Unleash the full potential of your BMW Z4 (G29) with our Titanium Semi-Closed Cold Air Intake System, engineered for the B58 3.0L turbocharged inline-six shared with the GR Supra.

Constructed from high-tensile, multicolored titanium, this intake offers superior durability, lightweight performance, and excellent thermal resistance compared to conventional materials. The exotic rainbow titanium finish not only resists extreme under-hood heat but also adds a head-turning motorsport aesthetic to your Z4’s engine bay.

The system features a clear polycarbonate view window built into the lid, allowing you to showcase the filter element and perform quick visual inspections without removing the housing.

Designed as a semi-closed intake, it delivers the raw airflow of an open-cone system while shielding the filter from excess heat soak. This ensures your B58 turbos are consistently supplied with cool, dense air — translating into real-world performance gains.

Benefits you’ll notice immediately:

1. Sharper throttle response and reduced turbo lag
2. Faster turbo spool with a more aggressive induction sound
3. Stronger midrange torque for confident pulls and overtakes
4. Horsepower gains that grow even further under ECU tuning

More than just numbers, this intake redefines the Z4’s character with a deep induction roar, enhanced turbo spool, and satisfying blow-off acoustics that make every drive more exciting.

Backed by high-temp silicone couplers, reinforced clamps, and precision-fit titanium housing, this intake is designed to handle everything from spirited daily driving to high-boost, track-ready builds.
