Show original supplier description
The Nissan 16175-JK21A is a genuine OEM adapter gasket, also referred to as an intake manifold seal, designed to restore the integrity of your intake system. As a direct-replacement part, it replaces the previous 16175-JK20A design. This component is specifically compatible with the 2006-2008 Nissan 350Z (3.5L VQ35HR engine) and the 2009-2020 Nissan 370Z (3.7L VQ37VHR engine). When performing maintenance, please note that this application requires a quantity of two gaskets to complete the installation properly. All genuine parts are backed by the manufacturer's factory warranty.
