CSF Stepped-Core Intercooler — N55 (F2x / F3x / F87 M2)

$895.00

CSF stepped-core front-mount intercooler for the N55 — a direct air-to-air upgrade for the F2x/F3x and F87 M2. Unlike the water-to-air cars, the N55 cools its charge air with a front-mount intercooler; the OEM core heat-soaks under repeat pulls and bleeds power as intake temps rise.

What CSF changes

CSF's stepped-core design fills the available opening more completely than a flat core — they call it the largest drop-in intercooler in the class. Bar-and-plate core, rounded cast end-tanks, developed in CSF's wind tunnel and 3D-scanned for fit. CSF measures intake temps about 38°F (21°C) lower than stock after three consecutive pulls. Fully reversible to OEM.

Finishes

We spec these with a Thermal Heat Dispersion coating by default — an emissivity coating that helps the core radiate heat away, which is exactly what you want on a cooler. Prefer to skip it? Raw or Black are available for less. Choose above.

Fitment

N55 — F30/F31/F34 335i, F32/F33/F36 435i, F22/F23 M235i, and F87 M2 (N55, 2016–2018). Confirm your chassis in the selector.

This is the intercooler-side core of an N55 Stage 2 build. The Stage 2 Kit — N55 packages the matched parts + calibration for 8% under à la carte.

WHY WE SHIP CSF
CSF builds the radiators, heat exchangers, and charge coolers we use when the factory cooling stack can no longer keep up with the load a tuned car puts on it. The cores are engineered to factory fitment, so the upgrade goes in at the OEM locations without fabrication. On the heat-exchanger-cooled engines, the charge cooler is often the single highest-leverage cooling part, and CSF's units carry the thermal capacity to keep intake temps stable through repeated pulls. We ship CSF where a build needs more cooling than stock without giving up clean, factory-style integration.
