Product Description

Upgrade the weak factory plastic cold side charge pipe on your 2012-2019 BMW 640i 3.0L Turbo N55 with the HPS Performance Cold Side Charge Pipe Kit. Built from mandrel-bent 6061 aluminum with a larger 3-inch design, this direct bolt-on upgrade improves airflow, throttle response, and boost efficiency while helping reduce common boost leaks found in the factory setup. Dyno-proven gains of up to 5 wheel horsepower and 5 lb-ft of torque make it a simple upgrade for sharper response and more consistent turbo performance.

Designed as a direct replacement for the factory cold side intercooler pipe, this upgraded aluminum charge pipe improves durability, airflow, and long-term reliability under boost. It includes a reinforced oil-resistant silicone coupler, stainless steel T-bolt clamps, a replacement throttle body O-ring, and all required installation components in a clean bolt-on design that installs with no cutting, no tuning, and no modifications required.
