CSF Billet Intake Manifold + Integrated Charge Cooler (Water-to-Air

Billet intercooler intake plenum for Toyota GR Supra MK5 and BMW G‑chassis B58

Take your B58 build beyond stock limitations with a CNC machined, high performance intercooler manifold that integrates a large water to liquid core inside a robust billet aluminium plenum. Developed to solve the well known bottleneck of the factory assembly on Toyota GR Supra A90 and G‑series BMW platforms, this upgrade delivers serious cooling efficiency and reliable power on fast road, track and drag setups.

Designed through extensive R&D with hundreds of hours of engineering and validation, this manifold is all about colder charge temps, faster recovery between pulls and smoother airflow. The result is stronger performance you can feel and repeat, lap after lap and run after run.

Why enthusiasts choose this upgrade

• CNC billet aluminium construction for exceptional strength compared to the OE plastic unit
• High efficiency integrated water to air core that slashes heat soak and keeps intake temps consistent
• Reduced pressure drop across the system for improved response and better top end
• Supplied fuel rail and hardware for a top feed port injection setup to support additional fuelling needs
• Built specifically for B58 powered Toyota GR Supra MK5 and BMW G‑chassis applications

Real world gains you can trust

We have fitted this manifold on customer cars and our own builds, and the results are exactly what keen drivers want. Colder air going into the engine, consistent performance during back to back pulls, and headroom for bigger power without the usual thermal fade. Our customers love the quality, the fit and the way it unlocks potential for tuned B58 projects.

Perfect for

• Stage 2 and stage 3 turbo upgrades that need extra headroom
• Track days and spirited driving where heat management is critical
• Tuners adding supplementary fuelling via top feed port injection
