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).
This item fits the following BMW Chassis:
E70 X5M,E71 X6M,E70 X5 X5,E71 X6,E82,E90,E92,E93,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4 X4,F30,F32,F33,F34,F36
S63 engine applies to X5M/X6M only. Fxx M5/M6 uses S63TU engine and does not use a diverter valve at all.

In addition to the weak stock chargepipe, the factory N54 diverter valves can also be a source for boost leaks. The diverter valve takes overboost and re-directs it back through the intake and turbos instead of allowing it to pass into the intake manifold. It's the same as a blow off valve (BOV) but instead of releasing into the engine bay, it stays contained to the engine. The stock diverter valves (DV) are plastic and connect with more plastic into the chargepipe and turbo inlet pipes. The plastic can become brittle and crack even on stock engines and leak boost, which leads to a loss in power and performance.
Turbosmart has developed two kits to replace and upgrade the stock diverter valves - a direct replacement kit and a combination DV/BOV "Dual Port" kit (shown). This Dual Port Kit is a DV and a BOV together in one unit. An internal valve directs some of the charged air into the turbo inlets and the rest is dumped into the engine bay like a traditional BOV. The amount of boost released into the air is determined by an internal spring in the Dual Port unit (additional springs are also available). This allows you to custom tailor how much boost and BOV "whoosh" you hear. In addition to the DV/BOV combo, stronger silicone hose is included to connect them to the turbo inlet pipes (Vargas silicone inlets are recommended). The Turbosmart Kompact Dual Port will give you all of the strength and reliability you need to take your turbo build to the next level.
