IAG Performance Replacement Blow Off Valve Elbow for 2002-07 WRX & 2004-17 STI. The IAG billet elbow is a direct replacement for the factory piece which is not available separately from Subaru. Our elbow allows the added flexibility of being able to rotate 180° from the factory position. This feature is useful when being used with an aftermarket intercooler. The IAG elbow includes a new rubber o-ring and stainless steel screws.
