Nissan catalogs 16600-53F00 -> 16600-53F01 for the stock KA24DE injector. The seals and insulators are separate service items and must not be assumed included with every injector.
Fitment
Depressurize safely, confirm stock side-feed rail and installed injector, and inspect connector, wiring, rail cups, seals and insulators. Performance injectors require matching flow data and calibration.
Aftermarket options
New OEM stock-flow injectors, matched performance side-feed sets and top-feed conversion rails exist. A top-feed rail is a system conversion, not a direct supersession for the stock side-feed injector.
Before you buy
Fuel leaks are a fire risk. Confirm the stock side-feed rail, injector number, flow requirement, connector and every seal/insulator. Performance or top-feed changes require a complete matched fuel-system and calibration plan.
