Dinan is proud to announce its new CNC-Machined Cast Aluminum Charge Pipe for BMW B58TU / B58D Gen 2 engines. Designed to replace the factory plastic charge pipe with a stronger, smoother, higher-flowing solution, the Dinan charge pipe improves volumetric efficiency and flows more CFM than the stock component while maintaining a clean, black, OE-plus appearance. Whether installed on a stock vehicle for added confidence or paired with additional Dinan performance upgrades on a tuned B58 build, the Dinan charge pipe delivers the strength, airflow, fitment, and refinement modern BMW enthusiasts expect.
