Installation and compatibility

This is a competition-system component. Confirm the required air-to-air intercooler, charge plumbing, sensor layout, and fuel-system configuration before installation. Installation should be handled by a technician familiar with the engine platform.

• This product is for motorsport use only and requires extensive modifications to install.
• The throttle body flange is engineered to accommodate a larger 77mm S55 throttle body (BMW 13-54-7-597-871). CSF recommends using the VTT-FAB Extension Harnesses ( B58/S58 to S55 TB Conversion ) to simplify installation.
• The manifolds are precision manufactured with the highest tolerances and attention to detail possible. They are designed and engineered to take the abuse of high boost pressure and competitive use. Each one is assembled in house and inspected prior to shipment. CSF offers a 2 year limited warranty on these manifolds. However, that warranty will be void if the manifold is disassembled without prior consent from CSF.
