CSF Top Mount Intercooler / Charge-Air Cooler (TMIC) - Raw Aluminium - BMW M3 M4 F8X F80 F82 F83 S55 - Water-to-Air Intake Manifold Intercooler Brick - Direct Fit Plug and Play Uprated Intercooler Upgrade

CSF Top Mount Charge Cooler - Raw Aluminium - For BMW F8X M3 and M4 with S55

Give your F80 M3 or F82 F83 M4 the cooling headroom it deserves. This CSF top-mounted water-to-air charge cooler is a direct replacement that delivers colder intake temps, rapid recovery between pulls, and consistent performance on spirited road drives and track days. If you are looking for an uprated TMIC that keeps the S55 happy lap after lap, this is the proven choice.

We have fitted this unit on numerous customer builds at MJ Modifications and the feedback is the same every time - noticeably lower IATs, stronger back-to-back acceleration, and excellent resistance to heat soak. It is an easy win for reliability and repeatable power on tuned or stock cars.

Key highlights

• Cast aluminium end tanks with internal air dividers for smooth, even distribution across the core
• Approx 60 percent larger core volume than the factory unit for a big jump in thermal capacity
• Dual-pass, left-to-right cross-flow water circuit - far more efficient than the OEM single-pass vertical layout
• Liquid-to-air design optimised via CFD and real-world testing for stable temps under repeated runs
• Developed with 3D scanning and rapid prototyping for precise OEM-style fitment and maximum surface area
• Drop-in upgrade - uses the factory quick-connect water fittings and OE sensor locations
• Supplied in raw aluminium - perfect if you want to powder coat to match your build
• Backed by CSF warranty support for peace of mind
