Description

After countless requests from enthusiasts and tuners alike, IPOSMotorsport proudly presents the ultimate intake manifold upgrade for the BMW B48 and B46 engine platforms—including TU variants. Designed from the ground up for performance and reliability, this manifold addresses key limitations in the factory system by significantly improving airflow, cooling efficiency, and tuning flexibility.

This intake manifold is CNC-machined from billet aluminum and TIG welded for exceptional durability and thermal performance. It features a massive 80% larger water-to-air (W2A) intercooler core, delivering dramatically lower intake air temperatures (IATs), faster recovery from heat soak, and more consistent power delivery under demanding conditions.

Whether you're running aggressive tunes, upgraded turbos, or additional fueling systems, this manifold is fully compatible with our B48/B46 Port Injection Kit, and includes 1/8” NPT ports for methanol or nitrous injection.

  • CNC Billet Aluminum Construction
    Precision-machined and TIG welded for superior strength, durability, and heat management.

  • 80% Larger Integrated W2A Intercooler Core
    Vastly improves cooling efficiency and IAT stability, especially under high load and boost.

  • Meth/Nitrous Injection Ready
    Built-in 1/8” NPT ports allow easy integration for port-based power-adders.
