do88 Performance Intercooler – BMW F-Series N55 / N20 / B48 (M2 / M235i / 335i / 435i / 328i & More)

OVERVIEW

The factory front-mount intercooler on the F-series 2, 3 and 4 Series and the F87 M2 is small for a tuned engine. On repeated pulls or a hot day it heat-soaks, intake temperatures rise and the ECU pulls timing. The do88 ICM-280 is a drop-in aluminum replacement with more than double the core volume, built with continuous welds and developed in-house in Sweden.

Against the factory M2 intercooler, do88 measured 18 percent more airflow at the same pressure drop and an outlet temperature 22 °C lower. It mounts in the factory location with no cutting or modification, and fits the N55 M2, M235i, 335i and 435i as well as the N20/N26 and B46/B48 four-cylinder cars.
