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 CNC machined and polished billet 6061-T6 aluminium — precision fit, lightweight, corrosion resistant Designed for 2.75" OD aluminium pipe — easily modified for 2.5-3.0" pipes 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 Compatible Vehicles Compatible with any vehicle using a Denso MAF sensor, including but not limited to: Lexus ES300 — 1999-2003 ES330 — 2004-2005 GS300 — 2001-2005 LS400 — 2001-2005 LS430 — 2001-2005 RX300 — 1999-2003 RX330 — 2004-2005 Lotus Elise — 2004-2011 Exige — 2004-2006 Exige-S — 2007-2011 2-Eleven — 2007-2011 Mazda MazdaSpeed 3 MazdaSpeed 6 Saab 9-2X — 2005-2006 Scion xA — 2004-2006 xB — 2004-2005 tC — 2005 Subaru Forester XT — 2004-2008 Legacy GT — 2005-2009 Impreza WRX — 2002-2007 Impreza WRX STI — 2002-2007 Toyota 4Runner — 1999-2008 Avalon — 2000-2004 Camry — 2002-2006 Celica — 2000-2001 Celica GT & GTS — 2002-2005 Corolla — 2003-2008 Echo — 2000-2005 FJ Cruiser — 2007-2008 Highlander — 2001-2008 Matrix — 2003-2008 MR2 — 2000-2005 Prius — 2001-2008 RAV4 — 2001-2005 Sienna — 2001-2006 Solara — 2002-2008 Tundra — 2000-2008 Yaris — 2006-2008 Available Part Numbers 11-0001 — Weld-On MAF Sensor Flange, Denso Air Meter (2.75" OD) Why Radium Engineering? ✔ Designed and manufactured in the USA ✔ CNC machined polished 6061-T6 billet aluminium — precision fit ✔ Pre-tapped M4 threads — no additional machining required ✔ Trusted by professional motorsport teams and serious enthusiasts worldwide ✔ Exclusively distributed in Australia by Coore Genuine Radium Engineering product.
