Increase the performance and durability of your 2021+ BMW G8X M2/M3/M4 with the do88 charge tube. This system is designed to provide superior durability and improved performance, ensuring your vehicle runs at its peak!
Background
2021-later BMW G8X M2/M3/M4 models feature an S58 engine equipped with a Y-shaped plastic charge tube. This tube connects both turbos to the throttle body, routing turbo boost into the intake manifold. However, under high-boost conditions, especially in tuned cars, the original plastic charge tube struggles to handle the increased temperature and pressure, risking cracking and potential engine damage. This is a crucial concern for owners looking to improve their vehicle’s performance without compromising reliability.
Our Solution
To address this issue, do88 has developed a high-performance charge pipe system specifically for the 2021+ BMW G8X M2/M3/M4 models. Our charge pipe system is 15% less restrictive than the stock version, significantly improving flow and power potential. It replaces the fragile original plastic with a robust die-cast aluminum Y-pipe, significantly improving durability and preventing costly failures. The design features optimized transitions to minimize restrictions and improve airflow. We use CNC-machined turbo and throttle body adapters to ensure leak-free operation and a larger quick-release throttle body to match the throttle body’s internal diameter. For added functionality, our charge pipe includes two 1/8 NPT ports for methanol injection or boost pressure sensors, with plugs provided for those who choose not to utilize these features. Tests show that our charge hose achieves a flow of 960 CFM at 150 mbar (2.17 psi), a significant improvement over the OEM’s 835 CFM, ensuring both durability and improved performance.
Installation
The do88 charge hose kit for the 2021+ BMW G8X M2/M3/M4 is designed for a direct fit, ensuring a hassle-free installation process. It comes with everything you need, including silicone hoses, a mandrel-bent charge hose from the rear turbo, and a cast aluminum Y-pipe, to replace the stock charge hose system. This design not only increases heat and pressure tolerance, but also integrates seamlessly into the engine bay. Installation instructions are provided to guide you through the process, making it accessible to both professionals and enthusiasts looking to reliably upgrade their BMW’s performance.
