VRSF Charge Pipe Upgrade - 2016+ BMW M240i, 340i, 440i, 540i & 740i (B58)
The factory plastic charge pipe on BMW's B58 inline-six is a known failure point, and it only gets worse once boost climbs past stock levels. The VRSF Charge Pipe Upgrade replaces it with a single mandrel-bent aluminum pipe between the intercooler and throttle body that will not crack, split, or blow a coupler, while sharpening throttle response and cutting turbo lag.
It is a straightforward bolt-on for B58 owners running stock boost through a moderate tune, and it removes one of the more common points of failure in the B58 charge-air path.
Important Compatibility Information
- Two throttle body flange versions: a 3-bolt flange for 2016-2019 B58 cars and a 2-bolt flange for 2020 and newer B58 cars. Confirm your throttle body flange before ordering.
Construction
- Mandrel-bent, T6061 aluminum tube body
- CNC-machined billet aluminum flanges at the throttle body, intercooler, and vacuum connections, TIG-welded to the tube
- Durable wrinkle black powder coat finish
- Plugged 1/8 inch NPT bung for water/methanol injection, boost leak testing, or as a boost reference source
What's Included
- VRSF Charge Pipe (aluminum, powder coated)
- 4-ply silicone couplers
- Stainless steel T-bolt clamps
Not included: removing the factory pipe can disturb the throttle body's retaining c-clip and o-ring seal on some cars. Inspect both before reassembly and replace them if worn.

Frequently Asked Questions
Do I need a tune to run this charge pipe?
No. It is a direct bolt-in replacement for the factory pipe and works on stock or tuned cars.
Which flange version do I need?
Match it to your throttle body: 2016-2019 B58 engines use a 3-bolt flange, 2020 and newer use a 2-bolt flange.
What is the NPT bung for?
It ships plugged and can be opened for a water/methanol injection nozzle, a boost leak test fitting, or as a boost reference port.
Should I inspect anything else while the pipe is off?
Check the throttle body's factory c-clip and o-ring while you have access; replace them if they show wear before reassembly.
Should I pair this with a downpipe?
Many B58 owners upgrade the charge pipe alongside the VRSF Downpipe for B58 since both address common OE weak points in the same charge-air path; each works independently.
