MMR Performance FMIC/Charge Air Cooler Upgrade for BMW 135i 335i 335xi 1M (E82 E88 E90 E91 E92 E93 E8x/E9x) N54/N55 - Uprated Intercooler Kit, Bar & Plate, Direct-Fit Bolt-On, Stage 1/2

MMR Performance Uprated Charge Air Cooler for BMW E8x and E9x N54 and N55

Unlock dependable, repeatable power with the MMR Performance uprated charge air cooler for BMW 135i, 335i, 335xi and 1M applications. This direct replacement, bar and plate cooler dramatically improves charge temperature control, delivering a typical 20°C intake temperature drop versus the factory unit and a core volume increase of over 20 percent. Expect harder, longer pulls without heat fade, sharper consistency between runs and genuine gains even on standard calibration thanks to denser air.

Engineered with high-flow cast end tanks and an optimised core to keep pressure loss to a minimum, it retains crisp throttle response and turbo spool while adding serious thermal headroom for remapped N54 and N55 engines. OE-style connections mean a straightforward bolt-on install with secure fitment to the original charge pipes and mounts.

We run this cooler on our own builds at MJ Modifications and customer feedback has been outstanding. Cooler IATs, stronger mid-range and repeatable results on the road and on track. A proven cooling solution for daily-driven cars, spirited weekend use and circuit sessions alike.
