Performance Cold Air Intake System for BMW B58 3.0L Turbo (2019–2025)

This high-performance cold air intake system is designed to improve the airflow efficiency of the BMW B58 3.0L turbocharged engine. By replacing the factory intake with a high-volume induction path, this kit delivers cooler, denser air directly to the turbocharger. This results in measurable power gains, sharper throttle response, and a more pronounced turbo induction sound across the entire RPM range.

The system features a large-diameter 4" aluminum intake tube and a corresponding high-flow dry filter to minimize restriction. Both the intake tube and the integrated heat shield are finished in a durable black powder coating to resist engine bay heat soak and ensure long-term reliability.

Key Features

• Measured Power Gains: Typical increases of 14–16 horsepower and 10–12 lb-ft of torque.

• High-Volume Induction: Large 4" aluminum intake tube provides a smoother, unrestricted airflow path.

• Advanced Filtration: 4" high-flow dry cone air filter provides high filtration efficiency without the need for oil.

• Thermal Management: Black powder-coated heat shield isolates the intake from under-hood heat.

• Improved Response: Provides faster throttle sensitivity and a stronger mid-range pull.

• Audible Turbo Sound: Increases the volume of the turbocharger induction and spooling sounds.

• Direct Fitment: Designed to utilize factory mounting points for a secure installation.

Installation Tip

Unplug the car battery's NEGATIVE GROUND CABLE before installing this product. After the installation is complete, leave the cable disconnected for at least 60 seconds. This allows the vehicle's ECU to reset and properly calibrate for the increased airflow, which helps optimize performance gains and prevents potential check engine light errors. Always perform installation on a completely cool engine to ensure safety.
