CSF High-Performance Stepped Core Bar and Plate Intercooler - Silver - BMW E9X 335i N54 N55
Upgrade your BMW E90, E92, E93 335i with the CSF stepped core bar and plate front mount intercooler. This is the go-to BMW 335i intercooler upgrade for anyone chasing reliable power, lower intake air temperatures, reduced heat soak and strong performance on road and track. Perfect for N54 and N55 owners running stock turbos, hybrid turbos, remaps, Stage 1 and Stage 2 tunes who want consistent, repeatable power without the factory intercooler holding them back.
We run this CSF FMIC ourselves and our customers have been genuinely impressed with the real-world gains in consistency and the sharp response under repeated pulls. If your N54 or N55 is seeing rising IATs, timing pull or power fade after a few hard runs, this BMW intercooler upgrade solves it.
