Description
Unlock the full airflow potential of your BMW G-Series B48 engine with the Untd. Performance Billet Intake Manifold, engineered for maximum strength, improved boost efficiency, and superior performance over the factory plastic manifold. Designed specifically for G20/G21 320i & 330i and G22/G23 420i & 430i, this manifold provides the durability and flow needed to support tuned, hybrid-turbo, and high-boost applications.
Constructed from precision CNC-machined billet aluminum, this manifold offers increased plenum volume, optimized runner geometry, and consistent airflow distribution—resulting in sharper throttle response, improved turbo spool, and higher horsepower capability across the entire powerband.
Key Features
High-Flow Plenum & Runner Engineering
A larger, optimized plenum combined with smooth, equal-length runners improves cylinder balance, increases volumetric efficiency, and enhances top-end power—ideal for elevated boost levels.
Billet Aluminum Strength for High Boost
Unlike the OEM composite manifold, the Untd. Performance billet design withstands extreme heat and boost pressure, making it perfect for Stage 2, Stage 3, hybrid turbo, and big-turbo builds.
Improved Turbo Efficiency & Response
Reduced turbulence and more stable airflow help the turbocharger spool quicker and maintain boost more effectively, improving mid-range torque and top-end performance.
Supports Advanced Tuning & Fueling
Engineered with provisions for additional fueling solutions (if required), giving tuners the flexibility needed for high-horsepower B48 builds.
Direct Bolt-On Fitment
Fully compatible with OEM sensors, mounts, and hardware for straightforward installation with no modification required.
