N55, S63 Electric Turbo Diverter Valve
- Mfg Part #
- Turner Part #
The diverter valve is responsible for redirecting boost away from the intake when it's not needed. Other cars use a blow-off valve to vent the pressurized air into the atmosphere (the whoosh sound commonly heard on turbo engines) but BMW and other makers use a diverter valve to keep the air circulating through the intake for emissions purposes. A failing diverter valve will lead to a boost leak as turbocharged air leaks past the seals instead of going into the engine when you want it. This is a minor issue on stock engines but a bigger issue on tuned or heavily modded engines (those will use an aluminum diverter valve instead of the stock plastic). The factory diverter valve is plastic which is prone to cracking and electric which will fail without warning. This is a direct replacement diverter valve for cars with the N55 and S63 (X5M/X6M) engines.
N55 takes 1 diverter valve.
S63 takes 2 diverter valves (1 per turbo).
