AIRTEC Motorsport S55 Billet Top-Mount Chargecooler / Intercooler Upgrade - Pro-Series Black - BMW M2 Competition F87, M3 F80, M4 F82/F83 - Water-to-Air Manifold TMIC - Direct-Fit Plug & Play Heat Soak Fix, UK Made

Billet Top-Mount Charge Cooler for BMW S55 - M2C F87, M3 F80, M4 F82 F83

Give your S55 twin turbo straight-six the cooling headroom it deserves. This AIRTEC Motorsport billet, top mounted charge cooler is engineered in the UK to stabilise intake air temps on hard-driven road cars and track toys alike. It sits in the factory location, connects to the original hoses and fixings, and transforms consistency by fighting heat soak on repeated pulls, fast laps and hot days.

What makes it special

• CNC machined billet aluminium end tanks with internal diverters for even distribution across the full core
• High capacity core designed to fit the OE position for maximum cooling efficiency
• Lower restriction design for improved flow and reduced pressure drop
• Bolt-on fitment that uses the stock damped bracket, boost couplers and coolant quick-connects
• Stealth Pro-Series black finish with engraved tanks and caps
• UK designed and manufactured for quality and reliability
• Registered Design Right number: 6082518

Proven temperature control

Back-to-back logging on a tuned S55 running Littco L640 hybrid turbos at 648 bhp and 684 lb ft showed a typical rise of 39 degrees on the factory unit across a 2,000 to 7,500 rpm pull, compared to around 9 degrees with this billet cooler in the same conditions. That means stronger repeatability, safer IATs and power that holds pull after pull.

Built for tuned and stock S55 cars

Whether you are Stage 1, Stage 2 or running upgraded turbos, the top mount water-to-air system benefits massively from improved charge air cooling. The precision machined internals direct airflow efficiently through the core, helping the ECU keep timing and boost where you want it. Ideal for daily use, fast road, drag strip and track day abuse.

Why billet aluminium

Billet construction allows ultra precise sealing faces and internal geometry that guides the charge air through the core efficiently. The result is a freer flowing, higher capacity cooler that resists heat soak and delivers consistent performance when it matters.
