Factory original rubber pipe from the turbo to the front intercooler on N55 engines in F22 M235i, F30 335i, and F32 435i.
This part is listed by BMW as BMW part number 13717602652 (13 71 7 602 652) and is described as an aluminum Hot Side Charge Air Tube (Boost Pipe) for F22/F23 M235i (2014-2016), F87 M2 (2015-2018), F30/F34 335i (2012-2015), and F32/F33/F36 435i (2014-2016), including Hybrid 3 and the M235i/M240i Racing models.
This upgraded pipe is made from aluminum with a silicone flex coupler. The aluminum is much more robust than the stock piece and will never get weak and brittle from exposure to heat and chemicals. If you're doing any work with the charge pipes, intercooler, or turbo you should consider upgrading this part to prevent a boost / air leak that can have you chasing codes and problems. This installs just like the factory - connection to the turbo outlet snout and the fitting on your stock-style intercooler. A Viton o-ring is included. If you're upgrading your M235i / 335i / 435i turbo, we recommend an upgraded boost pipe for best results. This turbo outlet pipe works on the F chassis N55 models such as the M235i, 335i, and 435i, including RWD and xDrive AWD “xi” models.
