MMR Competition Intercooler Upgrade for BMW N55 F20 F21 F22 F30 F31 F32

Give your turbocharged BMW the cooling headroom it deserves. This MMR front mount charge cooler is a lightweight, high-flow, stepped tube-and-fin design that keeps intake temperatures stable, resists heat soak and helps your N55-powered BMW deliver repeatable performance on fast road and track. It bolts straight in with factory-style connections for a tidy, hassle-free install.

Real-world gains you can feel

• Rapid recovery between pulls, stronger mid-range and consistent power delivery on spirited drives.
• Low restriction for minimal lag and efficient turbo operation, ideal for remapped Stage 1 and Stage 2 builds.
• Excellent cooling efficiency that curbs heat fade during back-to-back acceleration and track sessions.

Why this uprated FMIC stands out

• Stepped tube-and-fin core measuring 520 mm x 215 mm x 145 mm for outstanding heat rejection.
• Approximately 70 percent larger frontal area than the factory cooler for superior airflow exposure.
• Around 90 percent more internal volume than OE to stabilise IATs under sustained load.
• Flow-optimised end tanks with internal turbulators for even charge distribution across the core.
• Anti-corrosive thermal coating for durability in all UK weather conditions.
• Direct replacement with OEM-style fitment, no cutting and no permanent modifications.
