IAG 3" Aluminum MAF Mounting Flange For 2002-07 Subaru WRX, 2004-07 STI

The IAG 3” Aluminum MAF Mounting Flange is machined from strong, yet lightweight billet aluminum. This flange is designed to work with the OEM Subaru mass air-flow sensor and is a direct fit for 2002 through 2007 Subaru WRX and 2004 through 2007 Subaru STI models. If you're fabricating your own short ram intake or cold air intake system, the IAG MAF Mounting Flange provides a precision fitted mounting point for your factory MAF and O-ring.

The IAG 3” Aluminum MAF Mounting Flange is designed to be welded to a custom 3” outer diameter aluminum pipe as part of a non-restrictive flow intake system. A larger diameter intake setup increases the airflow to the engine, providing the potential for more horsepower.

IAG’s 3” Aluminum MAF Mounting Flange is constructed from 6061-T651 aluminum. Chosen for its strength and lightweight composition, our billet flanges are resistant to bending, twisting, cracking and corrosion. The IAG 3” Aluminum MAF Mounting Flange makes your intake fabrication project easier by providing a fit that closely matches the pipe's tolerances and effortlessly aligns with the OEM MAF and O-ring.

The IAG 3” Aluminum MAF Mounting Flange requires fabrication and welding to use, but the installation process is simplified by its precision design. Our MAF Mounting Flange features a machined lower edge to closely match the curvature of your custom 3” aluminum intake pipe, allowing you to get a clean and precise weld around the edges of the flange. This fitted flange saves you the expense of paying a machinist for a custom part and avoids the time-consuming task of grinding for an accurate fit.
