Overview

The CTS Turbo cold air intake is a complete replacement for the factory airbox system designed for BMW B58 3.0L engines. It aims to be the largest, loudest, and highest-flowing intake on the market. The system features a massive 6″ reusable air filter and a 4″ aluminum pipe that connects directly to the turbo inlet.
