MMR Performance Front Mount Intercooler (FMIC) Upgrade for Mini F56 F55 Hatch, F54 Clubman (F5x) Cooper, Cooper SD, One B38 B48 B37 B47 2013+ Stepped Tube & Fin Core

Uprated Charge Cooler Upgrade for Mini F5x Platform

Unlock reliable, repeatable performance from your Mini with this high-flow alloy charge air cooler. Engineered for the F5x chassis, it slashes intake temperatures, resists heat soak and keeps boost delivery crisp on fast road, track days and mapped cars. Expect cooler charge air, stronger mid-range and consistency pull after pull without unwanted lag.

We run this cooler on our own demo cars and customer builds, and the feedback has been superb for temperature control and real-world drivability. It is the cooling solution we trust when power should stay the same at the end of a spirited drive as it was at the start.

Why switch from the factory unit

The stock heat exchanger is easily overwhelmed under hard use, especially on tuned engines. Intake temps climb, the ECU pulls timing and performance fades. This stepped, tube-and-fin core gives a major increase in surface area and internal volume for rapid heat rejection and quick recovery between pulls, all while keeping pressure drop to a minimum.

Key advantages

• Big reductions in charge temps for dependable power and torque run after run
• Stepped tube-and-fin construction for excellent cooling efficiency with low restriction
• Smoother, more consistent boost delivery and throttle response
• Durable anti-corrosion thermal coating for long-term reliability
• Direct-fit, bolt-on install with no cutting or permanent modifications

Technical highlights

• Core size: 580 mm x 231 mm x 110 mm stepped layout
• Approximately 70 percent larger frontal area compared to OE
• Approximately 90 percent more internal volume than the factory cooler
• CFD-optimised end tanks for even flow distribution, with internal turbulators to enhance heat transfer
• Approximate weight: 9.2 kg

Designed to balance maximum intake temperature reduction with minimal pressure loss, this upgrade is ideal for stock cars, Stage 1 and Stage 2 remaps where dependable, repeatable performance matters.

Vehicle compatibility

• Mini Hatch F56 3-door, F55 5-door, Clubman F54, F5x platform, 2013 onwards
• Petrol: B38 1.5 turbo, B48 2.0 turbo
• Diesel: B37 1.5, B47 2.0
• Variants: Cooper, Cooper SD, One
