Maximize Airflow. Gain Power. Clean Installation.
This kit includes everything needed to install an OBD2 M/S52 throttle body and OBD2 M/S52 fuel rail onto an OBD1 M50 intake manifold. Unlike other kits on the market, we’ve designed this with a dedicated dipstick tube mount for a clean, factory-like installation. All hardware included.
 
Why Upgrade to the OBD1 Manifold?
The OBD1 M50 manifold has larger, higher-flowing runners than the restrictive OBD2 version, allowing for significantly improved airflow. When paired with our tuning package, this upgrade facilitates:
15-20WHP gains with no low-RPM power loss
Increased top-end power for naturally aspirated and forced induction setups
Better throttle response and improved breathing at high RPM
 
Kit Features:
Full Compatibility – Adapts the OBD2 M/S52 throttle body and fuel rail to the OBD1 M50 manifold.
Lifetime Durability – Laser-cut stainless steel construction for unmatched strength.
Clean Installation – Includes a dipstick tube mount for a secure and professional install.
OEM BMW Gaskets
 
Important Notes:
You will need the correct throttle boots and IACV hoses to complete the install. These are available as OEM parts, or we offer upgraded options if needed.
Designed in-house and tested for real-world performance.
 
Available Variations:
Kit with OEM Replacement Gaskets – Includes new gaskets for a complete refresh.
Complete Swap Kit (No Replacement Gaskets) – For those who already have gaskets and just need the adapter components.
 
Unlock the full potential of your M50 manifold—more power, better flow, and a clean install with 22RPD.
