This Original Equipment Manufacturer part is the same part that was made & installed by the car manufacturer at the factory where the car was produced.
Per the Nissan Service File, this intake valve replaces the original valve #13201-7S000, which is no longer available. To use this valve as a replacement for an original valve, the valve lifter will also need to be replaced with a shorter version. Please refer to Nissan Service Bulletin #NTB13-081a or contact your local dealer for more information.
