NTK 24572 Oxygen Sensor - Downstream Left, Downstream Right or Intermediate

NTK Direct Fit Oxygen Sensor for Nissan and INFINITI

NTK Oxygen Sensor 24572 is a direct fit, heated oxygen sensor built for specific applications with OE-style fit, form, and function. It is designed for downstream and intermediate locations on select Nissan and INFINITI vehicles, including Sentra, Maxima, and I30 models.

With a 4-wire heated design, 18 mm threaded mounting, and a 36.25-inch wiring harness, this sensor is built for precise replacement where the original sensor location and connector layout matter. NTK 24572 is engineered for direct replacement service on emissions systems that require accurate exhaust feedback.

Key Features

• Direct fit oxygen sensor for specific Nissan and INFINITI applications
• Heated sensor design for faster operating response
• 4-wire configuration for OE-style signal and heater circuit layout
• 18 mm threaded mounting type
• 36.25-inch wiring harness length
• OE-equivalent design for downstream and intermediate sensor positions

Product Details

NTK is known for oxygen sensor manufacturing across import and domestic applications, and Part Number 24572 reflects that OE-focused approach. The sensor uses NTK’s ceramics expertise and production controls to maintain consistency from raw material through finished component. It is extensively tested during manufacturing to help ensure reliability and conformance to OE specifications.

This part cross-references Bosch 13348 and DENSO Auto Parts 234-4777 for the same application. It is a direct replacement choice for drivers servicing emissions-related faults on Nissan Maxima, Nissan Sentra, and INFINITI I30 platforms where the original sensor location and connector style must match.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream or intermediate sensor readings
• Incorrect air-fuel feedback from a worn sensor
• Emissions test failures caused by sensor degradation
• Slow heater response in heated oxygen sensor circuits

Installation Notes and Fitment

Compatible With select 1998-2002 Nissan and INFINITI applications. Fits 2000-2002 Nissan Sentra, intermediate; located after manifold 3-way catalyst, B1S2, clean air vehicle. Fits 2000-2001 INFINITI I30, downstream left. Fits 2001 Nissan Maxima, downstream left. Fits 2001 Nissan Sentra, downstream right, grey connector, exc. clean air vehicle. Fits 1999-2000 Nissan Maxima, downstream left, Calif. emissions. Fits 2000 Nissan Sentra, downstream right, exc. clean air vehicle. Fits 1999 INFINITI I30, downstream left, Calif. emissions. Fits 1998 Nissan Maxima, downstream left, from 6/98, Calif. emissions.

Verify sensor position, emissions calibration, and connector style before installation. The threaded mount and harness length should be matched to the original routing for proper fitment on the vehicle.
