Performance Intake Manifold w/Fuel Rail 2016-2025 BMW - B48/B46 (Gen 1 & Gen 2)

Your B48 makes good power until heat soak shows up and steals it. The stock plastic manifold traps intake temps, and on back-to-back pulls or a hot track day you feel the car go soft. This is the fix.The RPM B48 MAX is a billet CNC aluminium intake manifold with an integrated air-to-water (W2A) intercooler core sized well above stock. Lower intake temps, less heat soak, faster recovery between pulls, and a solid foundation once you start pushing past Stage 2.What you get Billet CNC aluminium manifold, TIG welded Integrated W2A intercooler core, 120mm thickness, high-flow design Upgraded fuel rail (gold) included Phenolic thermal-rejection spacer to stop the manifold soaking heat straight off the head 1/8" NPT provisions for meth or nitrous injection All mounting hardware and clamps FitmentFits BMW B48 and B46 2.0T engines, both Gen 1 and Gen 2 (B48TU).
