Spool Performance Charge Pipe Upgrade Kit

For 2016–2024 F & G Series M140i, M240i, 340i, 440i, 540i, 740i, X3 & X4 BMWs with the B58 Engine Gen 1 & Gen 2

Give your B58 the performance and durability it deserves with the Spool Performance Charge Pipe Upgrade. Designed to improve throttle response and reduce turbo lag, this charge pipe is a must-have for both stock and tuned engines. The stock charge pipe is known for cracking under pressure, and this upgrade ensures your engine won’t let you down.

Crafted from T6061-grade aluminum, the charge pipe is TIG-welded and finished with a sleek wrinkle black powder coat for a clean, factory-like look. It’s built to handle high boost levels and features three 1/8" NPT bungs with stainless steel plugs, offering flexibility for water injection, boost testing, or as a boost source.

To ensure reliability and a leak-free fit, it comes with CNC billet aluminum flanges for the throttle body, intercooler, and vacuum connections. We also include silicone couplers and stainless steel T-bolt clamps for a complete installation. Tested on multiple fitment jigs, this charge pipe upgrade is ready to handle anything you throw at it.
