B46/B48 Aluminum Charge Pipe F/G Series Gen 1 & 2

B46/B48 Aluminum Charge Pipe – BMW F & G Series | Gen 1, Gen 2 & Gen 3

Upgrade one of the most common failure points on your BMW with the MBS B46/B48 Aluminum Charge Pipe. Engineered for Gen 1, Gen 2, and Gen 3 B46/B48 engines, this high-flow charge pipe replaces the restrictive factory plastic unit with a durable aluminum design built to withstand increased boost pressure and higher horsepower applications.

Manufactured from high-gauge aluminum, this charge pipe features precision CNC-machined throttle body and turbo flanges for an OEM-quality fit and a smooth, unrestricted airflow path. Finished in a durable black textured powder coat, it blends seamlessly into the engine bay while providing superior durability over the factory plastic charge pipe.
