This T4 Spacer is designed for use with T4 Turbos installed on Duramax engines when an extra 1.0 inch or 1.5 inch of elevation out of the valley is required, although it could be used in any T4 application.
Note: A T4 gasket should be used on the top and bottom of the spacer to provide a proper seal.
