SLE Charge Pipe – BMW B58 Gen 1 (M240i / 340i / 440i / 540i / 740i / X3 M40i / X4 M40i) 2016–2019 – Wrinkle Black

Description:
Upgrade your factory plastic charge pipe before it fails — the SLE Charge Pipe is a must-have for any Gen 1 B58-powered BMW. The OEM unit is prone to cracking and blowing off under boost, especially on tuned cars. Our upgraded charge pipe solves that with a durable aluminum construction and wrinkle black powder-coated finish for a clean, OEM+ look.

Designed for performance and reliability, this charge pipe features smooth mandrel bends for optimal airflow, CNC-machined flanges for a perfect fit, and a pre-welded 1/8” NPT bung for meth injection or additional sensors. It includes all required silicone couplers and stainless steel clamps for a hassle-free, bolt-on installation.

Whether you’re stock or tuned, this upgrade ensures better throttle response, boost reliability, and long-term peace of mind.
