BMW G20/G21 3 Series Aluminum Air Intake Manifold with Built-In Intercooler – Integrated Charge Cooling, Enhanced Airflow & Boost Efficiency | Fits 2019–2025 (B58TU Gen 2 Engine)

Upgrade your B58-powered BMW with the BAVMODS® Aluminum Air Intake Manifold with Integrated Intercooler, engineered to deliver cooler charge air, improved airflow efficiency, and maximum boost stability under demanding performance conditions.

This high-performance manifold features a built-in air-to-water intercooler core, allowing for drastically reduced intake air temperatures (IATs) and a denser air charge directly entering the combustion chamber. The result is improved throttle response, increased power consistency, and safer operating temperatures — especially during high-load or tuned applications.

Constructed from CNC-machined and TIG-welded aluminum, this manifold is designed to withstand extreme boost pressures without the flex or heat soak commonly seen in OEM plastic units. Internal flow paths have been CFD-optimized to ensure balanced air distribution across all cylinders, supporting both stock and upgraded turbo setups.

Perfect for enthusiasts looking to push their B58 Gen 2 engine further — whether on the street or track — this manifold combines precision engineering, heat management, and mechanical strength in one powerful upgrade.

Key Feature

• Integrated Air-to-Water Intercooler Core – Reduces charge air temperature for denser airflow and improved combustion.
• CNC-Machined Aluminum Construction – TIG-welded for superior strength and long-term reliability.
• Improved Boost Efficiency – Minimizes pressure loss and enhances turbo response under load.
• Balanced Cylinder Airflow – CFD-optimized runners ensure even air distribution for consistent power delivery.
• Superior Heat Dissipation – Aluminum housing resists heat soak far better than OEM plastic manifolds.
• Supports Tuned & High-Performance Applications – Ideal for upgraded turbos, E85 tunes, or heavy track use.
• Direct Bolt-On Installation – Retains factory mounting points and sensors.
• Engineered for the B58TU (Gen 2) Platform – Precision-fit for the latest B58 architecture.

FITMENT: Compatible with G20/G21 3 Series (B58 Gen 2) models equipped with the B58 Gen 2 / B58TU engine, including:

Fits both RWD and xDrive variants.

Direct bolt-on installation – no permanent modifications required.
