Performance Cold Air Intake System for BMW E46 3-Series – High-Flow Aluminum & Sport Sound

This cold air intake system is designed to improve the induction efficiency of the BMW E46 3-Series equipped with inline-six engines. By replacing the restrictive factory air box with a lightweight T304 aluminum induction path, this system allows the engine to draw in air more freely. This results in measurable increases in power, sharper throttle response, and a more pronounced, sporty engine note during acceleration.

The system features a high-flow red filter that provides superior filtration while maximizing airflow volume. Constructed for long-term durability, the aluminum piping is resistant to corrosion and designed to fit within the engine bay without permanent modifications.

Key Features

• Performance Gains: Increases horsepower and torque by up to 10% for improved acceleration.

• T304 Aluminum Construction: Crafted from lightweight, corrosion-resistant aluminum for durability.

• High-Flow Red Filter: Designed for maximum airflow and superior particle filtration.

• Sharper Response: Improves throttle sensitivity for a more efficient and engaging drive.

• Direct Fitment: Replaces the factory air box and intake tube with a straightforward bolt-on design.

• Enhanced Acoustics: Produces a deep, aggressive intake sound under load.

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.
