What this part does

The exhaust manifold collects high-temperature exhaust gases from the engine cylinders and routes them into the turbochargers and exhaust system. In the BMW N63 "hot-V" engine architecture, these components are uniquely mounted inside the valley between the two cylinder banks, directly feeding the twin turbochargers. When these assemblies fail, they typically crack or warp from extreme thermal cycling, causing exhaust leaks, a distinct ticking noise on a cold start, loss of turbo spool efficiency, and sluggish engine performance.

Before you order

This listing includes both the left and right manifolds as a complete matched set from the vehicle it came from. Because these sit deep in the engine valley beneath the turbochargers, replacing them requires significant top-end disassembly. Always replace the manifold gaskets, turbocharger mounting hardware, and exhaust seals during installation, as reusing old hardware in this high-heat environment guarantees future exhaust leaks. Inspect your existing cylinder head studs before mounting.
