Superior performing front replacement turbo with the engineering and reliability you've come to expect from all Dinan parts. Revitalize your exhausted turbo with this high-grade replacement and enjoy driving again just like you did on day one. Our front replacement turbo is a rebuilt turbocharger that has been modified with a heavy-duty wastegate pivot, unlike the wear-prone stock wastegate pivot that commonly resulted in wastegate rattle. Our replacement turbochargers have been built to BMW's rigorous standards and testing to ensure compatibility. We guarantee our replacement N54 turbos with a 2-year unlimited mile warranty to secure your driving pleasure in the foreseeable future. Requires corresponding rear turbo (D310-0072 for E8x vehicles or D310-0073 for E9x vehicles) to function properly. Core Program: Turbochargers are part of the CORE program we utilize at Dinan so the listed price includes a core exchange fee. This fee will then be refunded to you once your old turbochargers have been received at Dinan and passed a quality check. This ensures we have a continuous stream of products for rebuilding purposes and the lowest possible price to the consumer. Any cores sent back that are damaged and/or unusable will not be given credit for. Please ensure adequate packaging and packing is being used to protect returning cores.
