BMW N55 Intercooler Upgrade – MMR High Performance FMIC for F20 F21 F22 F30 F31 F32 M135i M235i 335i 435i
Upgrade your BMW N55 with the MMR High Performance Intercooler and unlock reliable, repeatable performance. This direct-fit front mount intercooler is the go-to N55 intercooler upgrade for BMW M135i, M235i, 335i and 435i owners who want lower intake air temperatures, reduced heat soak and consistent power on road and spirited drives. Built around a huge bar and plate stepped core, it offers around 70% more frontal area and roughly 90% more internal volume than the OE intercooler for a serious cooling advantage without unwanted lag.
We have installed and run these ourselves and our customers have been delighted with the results. Expect cooler charge temps, stronger performance run after run and excellent build quality that fits like factory.

A Competition tube and fin alternative is also available for those prioritising lower core mass.
