S55 Aluminum J Pipe – F80 M3 / F82 F83 M4 / F87 M2 Competition

Upgrade your factory plastic J pipe to a precision-engineered CenCalMotorsport Aluminum J Pipe built to handle serious boost and deliver maximum reliability. The OEM plastic pipe is known to crack or split under pressure—our high-strength aluminum replacement eliminates that weak point while improving airflow and throttle response.

Each pipe is crafted from mandrel-bent aluminum for smooth, unrestricted flow and finished in a durable wrinkle-black powder coat to withstand heat and corrosion. Precision CNC-machined billet flanges ensure a perfect OEM fit and leak-free seal.

Two 1/8” NPT ports come pre-plugged, allowing easy integration of water/meth injection or boost reference sensors. Installation is straightforward and includes everything needed to replace the factory J pipe, including the retaining clip.
