CSF B58 Charge-Air Cooler Manifold (Satin Black) - Supra A90/A91 & BMW G-Series

If you are running a tuned B58 engine or planning to upgrade your turbo, the stock plastic intake manifold is going to be your biggest bottleneck. The factory unit is well-known for heat-soaking quickly and splitting open at the seams when you crank up the boost. The CSF 8200B completely replaces that weak factory setup with a solid, all-aluminum design that handles high boost all day without any issues.Inside this manifold, CSF packed a huge water-to-air bar-and-plate intercooler core. It cools down incoming air much faster than the stock core can. This keeps your intake air temperatures (IATs) low and stable, which means your car won't drop power or pull timing during hard runs at the track or drag strip. On top of that, the satin black powder coat finish helps keep under-hood temperatures down while giving your engine bay a clean, professional look.

Features and Benefits

  • No More Cracked Plastic: Built entirely from high-grade billet and cast aluminum with clean TIG welds. This means you can run aggressive boost levels without worrying about intake leaks or catastrophic failures.
  • Aggressive Heat Management: The upgraded bar-and-plate core drops intake air temperatures fast. It keeps your car performing consistently, avoiding the sudden power drops caused by heat soak.
  • Ready for Meth or Nitrous: You don't have to drill into a brand-new part. CSF pre-machined a 1/8" NPT port directly into every single cylinder runner. Just remove the plugs to drop in your nozzles.
  • Secondary Fuel Rail Included: The kit comes with a matching top-feed billet fuel rail and block-off plugs. If you decide to add secondary port injection later for huge horsepower goals, the hardware is already there.
  • True Bolt-On Setup: This is a direct replacement for the factory unit. It lines up perfectly with your stock brackets, map sensors, and coolant lines without needing any custom fab work.

Frequently Asked Questions (FAQ)

Do I need a custom tune right away after putting this on?
No. You do not need a new tune just to run this manifold. It works perfectly with your factory map sensors and stock ECU layout without throwing any warning lights. That said, you will see the absolute best results on cars that are tuned to run more boost.
Can I use this manifold if I'm still on the stock fuel system?
Yes, absolutely. The included billet fuel rail arrives out of the box with heavy-duty plugs pre-installed. If your fuel needs are covered by the stock direct-injection setup, just leave the plugs alone. If you upgrade to a big turbo later, you can easily plum your secondary injectors right into the rail.
Does the kit include the mounting gaskets?
Yes. CSF includes custom, heavy-duty O-ring gaskets inside the box. These create a tight, secure seal between the aluminum manifold runners and your engine's cylinder head, so you don't need to purchase brand-new OEM gaskets
