B58 Charge Pipe Upgrade Kit

The VRSF Charge Pipe Upgrade Kit is engineered to enhance the performance of F and G Series BMWs with the Gen1 B58 engine (B58A). It replaces the factory charge pipe, which is known to fail under stock and tuned boost levels. Constructed from mandrel-bent T6061 aluminum with CNC billet aluminum flanges for throttle body, intercooler, and vacuum connections, this kit ensures a precise fit and leak-free operation. The durable wrinkle black powder-coated finish provides a clean look within the engine bay. Additionally, a plugged 1/8" NPT bung is included for methanol injection or boost leak testing. The kit comes complete with 4-ply silicone couplers and stainless steel t-bolt clamps. It replaces BMW OEM part number 13718601684. It does not replace or fit models with OEM part number 13718651066 installed. This product is not for sale or use in the state of California on any pollution-controlled vehicle per CARB regulations. It is also recommended to replace the throttle body seal after removing the stock charge pipe to prevent leaks.
