Description
The OneFastShop B58 Gen 1 Charge Pipe Upgrade Kit is a direct replacement for the failure-prone OEM plastic charge pipe found on BMW’s Gen 1 B58 engines. Designed to replace BMW part number 13718601684, this aluminum upgrade provides superior reliability, improved throttle response, and long-term durability for both stock and tuned applications.
Manufactured from mandrel-bent T6061 aluminum and finished with a wrinkle black powder coat, this pipe includes CNC-machined flanges for a leak-free OEM-style fit. An integrated 1/8" NPT bung allows easy setup for meth injection or boost reference. The kit also comes complete with 4-ply silicone couplers, stainless steel T-bolt clamps, and all required installation hardware.
This kit is intended exclusively for Gen 1 B58 engines (2016–2019) and is designed for vehicles equipped with the three-bolt throttle body flange. It is not compatible with later B58TU engines (2020+) that use the two-bolt design.
