| The COBB BMW N54 Charge Pipe both increases flow and improves the reliability of your twin turbo BMW. The 3"" mandrel bent aluminum pipe replaces the brittle factory plastic pipe which can fail under increased boost pressure. The increased piping size helps to reduce turbulence and maximize flow into the engine.
For maximum effect, pair the Cobb Downpipe with a Turbosmart Kompact Plumb-Back Diverter Valve upgrade to fully eliminate the failure-prone plastic OEM diverter valve to prevent any potential for boost leaks.
Turbosmart Kompact Dual Port Blow Off Valve
| The Turbosmart Dual Port BOV can either be configured as a 50/50 (progressive porting give early valve lift recirculation and later valve lift vent to atmosphere), fully recirculation BOV or 100% vent to atmosphere. Your N54's stock system is a fully recirculation design that ""recycles"" the blown off air back into the turbo. The recirculation design does not provide that ""woosh"" BOV sound, but still will provide you with all the other benefits of upgrading your BOV. The Turbosmart Dual Port system includes a special blanking plug allowing you to set it as a 100% atmospheric vent, where the blown off air will vent to the atmosphere and will produce that ""woosh"" sound.
If you feel that you cannot properly perform this installation, we HIGHLY recommend you bring in your vehicle and let one of our technicians do the install.
