Review on Oxygen Sensor NTK 24401 by Radney Taala

Revain's This Part Fits Calculator shows it will fit 2004 (and many other sites too) , but you should check your plug before buying. This is because Nissan/Infiniti replaced the lambda sensors on this model with broadband sensors (NTK 24320) in mid-2004. The easiest way to determine this is to check the connection on any valve cover. If it is square with four pins and has no additional protrusions, then this is the model (non-broadband). If it's a six-pin rectangle, then it's broadband and you need it (NTK 24320). My friend has an early build 04' and no broadband (this model) but my car was built late in the production year and I have broadband which like others I discovered after ordering. just as good as OE (same manufacturer) at better price than brand/parts department. As long as you get the correct model number for your vehicle. Happy spinning!
