We had a customer install a larger turbo on his 2003-2005 Dodge SRT4 and he needed a reducer elbow so that he could use his AEM intake with the larger turbo.
This piece goes from 3 inch to 4 inch so that he could use his AEM intake, and connect the 3 inch aem intake to the 4 inch inlet turbo.
Part number on this 90 degree elbow that goes from 3 inch to 4 inch is 2785.
If you need one of these, give us a call and we would be happy to help you !
