The Rev9 Intake and Intercooler Charge Pipe Kit for the 2016–2021 BMW G12 740i and 740i xDrive is designed to improve airflow efficiency, boost reliability, and throttle response on the turbocharged B58 platform. Featuring high-flow mandrel-bent aluminum piping paired with reinforced silicone couplers, this upgraded system replaces the restrictive factory plastic charge piping that can become a known weak point under higher boost pressure, heat cycles, and long-term use. By improving airflow between the turbocharger and intercooler system, the Rev9 kit helps deliver smoother acceleration, more consistent boost pressure, and improved turbo response during both daily driving and spirited performance use.

Constructed from durable aluminum engineered to withstand elevated engine bay temperatures and increased boost demands, this kit is ideal for B58 owners who want improved reliability without sacrificing OEM-style fitment. The direct bolt-on design allows for straightforward installation while providing a noticeable improvement in airflow stability and throttle response. Many BMW enthusiasts upgrade factory charge piping early as preventative maintenance due to the known limitations of OEM plastic components under boost. Rev9 continues to be a popular choice among enthusiasts for delivering strong fitment quality, dependable performance gains, and real-world durability improvements at an accessible price point.
