Radium Weld-On MAF Sensor Flange, Denso Air Meter (Multi-Fit)

The Radium Engineering 11-0001 Weld-On MAF Sensor Flange is a CNC machined billet aluminium flange for Denso air meter (MAF sensor) installations on custom inlet pipes. Designed for fabricators and enthusiasts building custom intake systems, this flange provides a precision-machined, pre-tapped mounting point for the Denso MAF sensor — eliminating the need to source or machine a flange from scratch.

The machined radius is designed for use with a 2.75" outside diameter aluminium pipe, but can be easily modified to suit 2.5-3.0" pipes. Pre-tapped M4 threads are provided for the sensor mount.

Key Features

• Pre-tapped M4 threads — for Denso MAF sensor mount, no additional machining required
• Weld-on design — permanent, clean integration into custom inlet pipes
• Made in USA
