Description
Product overview
The CSF 8351 is the BMW G9X M5 High-Performance Charge-Air-Coolers.
An intercooler transfers heat out of compressed intake air before it reaches the engine. The core, ducting, and charge-pipe connections work together, so both airflow through the cooler and sealed plumbing matter during installation.

Installation and compatibility
Confirm the listed engine and chassis application, inspect charge-pipe seals and connections, and retain the specified airflow ducting. Follow the installation instructions and check the completed charge system for leaks.
- This product requires some minor modifications to install. The mounting pins that the coolers rest on will need to be shaved down to help the CSF coolers sit in a better position. CSF also recommends trimming the the air balancing tube to improve the fitment. The installation requires fine adjustments and aesthetic results will depend on the skill of the installer.
