BMW E8X 135i N54 Cooling Refresh and Rebuild Kits

Your 135 only has one weakness… the cooling system.

The ultimate assurance that you won't be left on the side of the road with an overheated engine is to refresh all the major components at the first sign of any failure.

In many cases, N54 engines last the life of the vehicle - meaning by this time there will be more wear and tear on cooling system components than predicted by BMW.

ECS offers Cooling System Refresh Kits with varying levels of components for this very reason - Two stages of ECS-assembled and Genuine BMW kits are available.
