Technical specifications

Installation requirements

Installing a performance manifold usually involves removing the turbocharger, heat shields and associated pipework. New gaskets and fasteners should be used, and engine tuning may be required depending on the setup. Fitting should be carried out by a performance workshop experienced with BMW turbo engines. Check that any modification meets Australian and New Zealand emissions, noise and certification requirements.

Fitment checks before ordering

This is an aftermarket upgrade part with limited fitment data. Confirm engine generation, chassis and VIN details before ordering. Keep your existing manifold until the new one has been test-fitted and compared.
