The IAG Performance AOS (Air Oil Separator) Strut Tower mounting bracket was originally designed to replace the standard mounting bracket included with early version 1 IAG's AOS kits. The redesigned bracket enabled installers to manipulate the AOS on the passenger side strut tower into a position to clear most rotated turbo kits, large TMIC's and FMIC's on the 2008-14 WRX, 2008-14 STI's and 2005-09 Legacy GT / Spec B.

The bracket, made from 3/16" aluminum, powder coated black, with mounting holes is supplied standard with the AOS's listed below.

This bracket is now the standard bracket included with the following IAG AOS'S:

IAG-ENG-7151 - Street Series AOS 08-14 WRX, 08-18 STI, 05-09 LGT
