OEM BMW Turbo Charger - N55 - 2011-2013 X5 & X6 35i - 11657583904

This part is listed by BMW as BMW part number 11657583904 (11 65 7 583 904) and is described as OEM Borg Warner turbo charger for N55 powered Twin-scroll single turbo BMW X5 and X6 models for the 2011, 2012 and 2013 model year. These are the 3.0 liter "TwinPower" turbo 6 cylinder models, which have a single turbo with two scrolls (and not two separate turbos, like earlier models did). Not for RHD models. 

On the BMW X5 35i and X6 35i, BMW switched to the N55 engine in 2011 as their chosen 6 cylinder Turbo platform. This particular N55 turbo was used in those X5 and X6 BMW models, including the 2011, 2012 and 2013 model X5 35i xDrive and 2011, 2012, 2013 and 2014 model X6 35i xDrive.

While most consider the change to the N55 turbo a step forward in reliability on the X5 and X6, we are seeing that turbo failures are still fairly common and expected on these BMWs with either high mileage, age, hard/aggressive driving, or higher levels of boost due to modification (or any combination of these factors). It seems clear that at some point in every N55's life a replacement turbo will likely be required. For this reason BimmerWorld carries high-quality, OEM replacement turbochargers that can have your "35i" powered X5 or X6 back to its original performance levels. A fresh Borg Warner turbo on the N55 power X5 and X6 will give you back the horsepower and torque you were missing, as well as resolve the mechanical and electronic warnings that may be present. 

Not for cars prior to the 2011 model year. 
Not for X5 built after the 2013 model year or X6 built after the 2014 model year.
