30th Apr 2026
Racing Dynamics Charge Pipe (2-Bolt) BMW B58 Gen 3 M340i G20/M440i G22/740i/X3 G01/X4 G02/X5 G05/X6 G06/X7 G07/Z4 G29/A90 - 139 10 58 042
Upgrade the reliability and performance of your BMW B58 Gen 3 engine with this high-performance 2-bolt aluminum charge pipe—engineered to replace the restrictive and failure-prone factory plastic piping. Designed specifically for modern BMW platforms equipped with the B58N engine, this charge pipe delivers improved airflow, increased durability, and enhanced boost handling capabilities.
The factory charge pipe is known to be a weak point, especially under higher boost conditions or tuned applications. This upgraded aluminum charge pipe eliminates that concern by providing superior structural strength and resistance to heat and pressure, ensuring long-term reliability even in high-performance builds.
Featuring a larger internal diameter and smooth mandrel-bent construction, the pipe reduces airflow turbulence and restriction, allowing for more efficient charge air delivery to the engine. This results in improved throttle response, better boost consistency, and optimized overall engine performance.
For added versatility, the pipe includes a pre-machined 1/8" NPT bung, allowing for easy integration of water/methanol injection systems, boost sensors, or temperature probes—making it ideal for enthusiasts planning future performance upgrades.
This is a true direct OEM replacement, engineered for precise fitment with factory connections. The kit includes all necessary hardware such as seals, O-ring, and retaining clip, ensuring a hassle-free installation process.
