The FTP BMW B58N charge pipe kit replaces the weak and inefficient factory plastic charge pipe, which becomes brittle and prone to cracking under heat and boost pressure. This BMW B58N charge pipe is engineered specifically for B58N engines produced from 2023 onward, with OEM reference number 13 71 9 455 373.

Product Features:

• Increased airflow
• Direct OEM replacement
• Enlarged pipe diameter
• 3-ply silicone couplers
• Bung for water / methanol injection
• Maximum reliability – no more cracked charge pipes

Technical Overview

The FTP charge pipe for B58N simultaneously improves airflow and significantly enhances engine reliability.

Its aluminum construction replaces the fragile factory plastic component that commonly fails under increased boost pressure. The reinforced design effectively eliminates the risk of leaks or rupture, even in vehicles operated under high load or performance driving conditions.

The increased diameter of the BMW B58N charge pipe reduces airflow turbulence and maximizes air delivery to the engine, resulting in sharper throttle response and more stable, efficient boost pressure across the RPM range.
