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.Product Specifications Brand: VRSF Product type: Charge pipe upgrade, engine bay Fitment: BMW B58-powered F and G-Series models SKU / MPN: V02D 10581030 (2016-2019, 3-bolt) or V02D 10581040 (2020+, 2-bolt) OE pipe replaced: BMW 13718601684 (3-bolt) / 13718651066 (2-bolt) Frequently Asked QuestionsDo 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.
