Description
Upgrade the performance and reliability of your BMW B58 engine with the Forge Motorsport high-flow aluminium boost (charge) pipe kit. Designed as a direct replacement for BMW OEM part number 13718601684, this precision-engineered solution eliminates the common failure point of the factory plastic charge pipe, especially under increased boost pressures from tuning or spirited driving.
This kit features mandrel-bent, single-piece aluminium pipework with a larger internal diameter to significantly improve airflow and reduce turbulence into the intake system. The result is optimized throttle response, enhanced turbo efficiency, and improved long-term durability.
The integrated CNC-machined billet couplers ensure a perfect OEM-style fitment, while the included 1/8” NPT methanol/water injection port and plug add future-proofing for advanced tuning setups. The powder-coated finish not only provides excellent resistance to corrosion and heat, but also adds a clean, professional look under the hood.
Additionally, the included silicone hose is constructed using Forge’s industry-leading Fluorosilicone inner liner. This specialized compound resists degradation from modern OAT (Organic Acid Technology) coolants and oil-laden air, ensuring long service life and consistent performance. It’s engineered to exceed OEM quality standards in both form and function.
