Step into a new level of B58 performance with the CSF Gen 2 B58 Race X Charge Air Cooler Manifold in Thermal Dispersion Black. This is the part you slap in when you want every last ounce of horsepower, sharper throttle response, and cooler intake temps on track or drag strip. Feel the surge as your M340i, Supra, or 540i delivers smoother, denser airflow with maximum efficiency. From launch to redline, the Race X keeps the boost tight and the engine breathing like a finely tuned race car.

This manifold was born in the lab and proven on the strip. Months of dyno testing, track runs, and real world data from Supra and BMW drag machines shaped every tube, port, and water channel. Engineers from CSF, VF Engineering, and Custom Plenum Creations pushed airflow, cooling, and reliability to the extreme. Every detail was tuned for ultimate performance while keeping heat soak in check and throttle response lightning fast.

Precision Engineered Design

Made from 100 percent billet aluminum and TIG welded for maximum strength. The core is 25 percent larger than the standard Gen 2 B58 manifold with 15 cooling rows. Thermal Dispersion Black finish fights heat soak. Integrated air divider balances airflow to all six cylinders. Includes KIYLEX thermal rejection spacer to cut intake manifold temps up to 15 percent. CNC machined ports for nitrous, methanol, and top feed port injection. Easy access to spin-off oil filter.

Configuration Options

Single pass or dual pass water flow with -16 ORB front port for ice box setups. Top feed fuel rail included. Individual 1/8 NPT ports for nitrous or methanol injection. Expanded vacuum and parameter pad with multiple sensor ports.

Exhaust Tips & Customization

This product is specific to the intake manifold, but CSF offers custom Thermal Dispersion finishes and raw billet options through the CSF custom finish program.

Production & Lead Time

Each manifold is made to order with care and precision. Expect a production time of 3 to 4 weeks depending on finish selection. Quality always comes before speed.

Fitment

⚠ Fitment Notes

CSF assumes that all users of this specific manifold will be running port injection. Because of this, the (qty. 6) port injection block-off bungs that come with our standard 8200 / 8300 manifolds are not included in this kit. If you would like to purchase these for your Race-X manifold, they can be purchased separately from your authorized CSF dealer or from CSF directly for $50.00 + shipping. (CSF product ID: F - qty 6) - please contact info@CSFrace.com by email to purchase with the subject line: "Race-X port injection bungs - request for purchase"

Mild Hybrid Models (48V systems) will require significant modifications to install. This includes an additional 8200S spacer (sold separately), shaving down the humps in the casting on the cylinder head, and shaving down the alternator.
