Product Details

NTK is the Sensor Specialist for import and domestic applications, and this Direct Fit Oxygen Sensor line is built around OE application coverage and consistent sensor performance. Part number 24404 is intended for downstream oxygen sensor locations on select Nissan Maxima, Murano, Altima, Quest, Sentra, and 350Z models, as well as Infiniti M45, FX45, FX35, G35, M35, and Q45 applications. This part cross-references Bosch 15523 and 15525 for the same application.

For buyers searching for a downstream oxygen sensor for 2004-2008 Nissan Maxima, a replacement oxygen sensor for 2003-2007 Nissan Murano, or an OE-style oxygen sensor for 2003-2006 Infiniti G35, this NTK 24404 offers the correct fitment profile for the listed positions. NTK’s manufacturing process uses ceramic control from raw material through finished sensor production, supporting consistent fit, form, and function across import applications.

Common Reasons to Replace

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn downstream sensor
• Reduced emissions system efficiency
• Slow sensor response or aging heater circuit issues
• Fault codes tied to B1S2 or B2S2 oxygen sensor locations

Installation Notes and Tips

• Verify the sensor position before ordering: downstream left, downstream front, downstream rear, or downstream as listed.
• Confirm thread diameter and harness length match the original sensor before installation.
• Inspect the connector and wiring route for heat damage or corrosion before connecting the new sensor.
• Use the vehicle’s service information to confirm the correct bank and sensor location for the application.

Quality Assurance

NTK oxygen sensors are extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. As the original equipment oxygen sensor supplier for many applications, NTK supports import and domestic coverage with OE-focused sensor technology.
