SLE Charge Pipe Upgrade for Gen 1 BMW B58 Engines (2016–2019)

Upgrade your factory plastic charge pipe before it fails! The SLE Charge Pipe is an essential upgrade for any Gen 1 B58-powered BMW. The OEM plastic pipe is known to crack or blow off under boost, especially on tuned vehicles. Our charge pipe addresses these issues with a robust aluminum construction and a wrinkle black powder-coated finish, delivering a clean OEM+ appearance with superior durability.

Designed for enhanced performance and long-term reliability, the SLE Charge Pipe features smooth mandrel-bent piping to maximize airflow, precision CNC-machined flanges for perfect OEM fitment, and a pre-welded 1/8” NPT bung for methanol injection or additional sensor integration. The kit includes reinforced 4-ply silicone couplers and stainless steel T-bolt clamps for a secure, hassle-free installation.

Whether running stock or tuned, this upgrade improves throttle response, boost reliability, and overall driving confidence with a direct bolt-on design—no tuning necessary.
