BMW N54/N55/S55 Throttle body VanJen Adapter

Midnight Motorsports 3.5" VanJen Adapter for N54, N55, and S55 Engines:
Say goodbye to boost leaks and blown-off charge pipes.

Tired of unreliable charge pipe connections? We’ve engineered the ultimate solution: our 3.5" VanJen Adapter, designed to bolt directly to the factory throttle bodies found on N54, N55, and S55 engines.

Whether you're daily driving or pushing high boost on the track, this upgrade eliminates common failure points. The VanJen clamp system offers a robust, leak-free seal while allowing up to 10° of misalignment, making installation and maintenance fast, easy, and secure—every time.

Key Features:

• Direct Bolt-On Fitment – For N54, N55, and S55 factory throttle bodies
• Boost-Proof Seal – No more hunting down leaks or risking charge pipe blow-offs
• Quick-Disconnect Design – Fast install/removal with 10° of flex for perfect alignment
• Premium Materials – CNC-machined from 6061-T6 billet aluminum, black anodized for durability and beauty
• Complete Kit – Includes all necessary hardware and 3.5" VanJen clamp for custom install (requires chargepipe modification - cut off existing flange and weld on the 3.5" flange)

Built for performance and reliability, this adapter is a must-have for any serious turbo BMW build.
