CSF Billet Intake Manifold & Integrated Charge Cooler/Chargecooler (Intercooler Manifold, W2A) for BMW B58 G-Series (M340i M440i Z4 M40i) & Toyota GR Supra A90/A91 - Inlet Plenum Upgrade, Port Injection Fuel Rail Ready

Transform your B58 with the CSF billet inlet plenum and integrated charge cooler for BMW G‑series and Toyota GR Supra Mk5 A90. Developed with over 1,500 hours of R&D, prototyping, machining and validation alongside VF Engineering and Custom Plenum Creations, this precision CNC unit replaces the factory manifold with a high efficiency air to water cooler built in. The result is stronger performance under sustained load, improved consistency on road and track, and the headroom your tune deserves.

We have fitted this upgrade for customers and on our own builds, and the feedback has been outstanding. Sharper response, steadier intake temperatures, and the confidence to run harder for longer without the usual heat soak issues that hold back tuned B58 cars.

• CNC machined billet construction for accuracy and durability, engineered for B58 powered BMW G‑series and GR Supra Mk5 applications
• High efficiency air to water core inside the manifold for rapid charge air cooling and excellent temperature control
• Reduced system restriction compared to the factory setup to support higher airflow and stronger top end
• Fueling upgrade ready with an included fuel rail and hardware for top feed port injection integration
• Developed with industry partners VF Engineering and Custom Plenum Creations to deliver a premium solution for serious builds
