Performance Intercooler for Mini F5x Cooper S - MMR Performance
Upgrade your Mini Cooper S F5x with the MMR Performance Intercooler and experience stronger, repeatable power with dramatically lower intake temperatures. This front mount intercooler FMIC is a direct-fit intercooler upgrade for the Mini F56, F55 and F54 Cooper S with the B48 engine. Expect a substantial drop in charge air temperatures, improved turbocharger efficiency and sustained performance on road and track, even on tuned Stage 1 and Stage 2 cars.
Designed around a huge tube and fin stepped core, this Mini Cooper S intercooler delivers almost double the core volume of the OE unit and around 70 percent more frontal area. The result is excellent cooling efficiency with minimal pressure drop so you gain power and torque without added lag. Internal turbulators maximise heat transfer and CFD optimised end tanks keep airflow uniform across the core.
We have fitted and tested this MMR Performance intercooler in-house at Nforcd and our customers have been delighted with the consistent performance during hard driving, with far less heat soak, faster recovery and stronger mid-range punch. If you are chasing reliable power from your Mini F5x Cooper S, this is the intercooler upgrade you want.
