NTK 24470 Oxygen Sensor - Downstream

NTK Direct Fit Oxygen Sensor 24470

NTK Direct Fit Oxygen Sensor 24470 is a heated, specific-fit oxygen sensor built for downstream applications where accurate exhaust feedback matters. It is engineered for direct replacement on select Lexus and Toyota models, including the Lexus ES300h, Toyota Avalon, and Toyota Camry.

NTK’s Direct Fit Oxygen Sensor line focuses on OE-style fit, form, and function. As part of the NGK family, NTK applies ceramic manufacturing expertise and extensive production testing to support consistent sensor performance for import and domestic vehicles.

Key Features

• Heated oxygen sensor for faster operating readiness
• Specific-fit design for direct replacement
• 4-wire configuration
• Threaded mounting type with 18 mm thread diameter
• 12.5 in. wiring harness length
• Downstream B1S2 application coverage for select Toyota and Lexus vehicles

Detailed Description

NTK 24470 is a direct fit oxygen sensor designed for downstream placement on select hybrid and gasoline applications. It is listed for 2013-2018 Lexus ES300h, 2013-2018 Toyota Avalon, and 2012-2017 Toyota Camry in downstream B1S2 positions, making it a strong match for buyers searching for a downstream oxygen sensor for Toyota Camry, a Lexus ES300h downstream O2 sensor, or a Toyota Avalon B1S2 oxygen sensor replacement. The sensor uses a threaded mount, 4-wire layout, and heated design to support OE-style exhaust monitoring.

This part cross-references Bosch (e.g., 13355, 15672) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn downstream sensor
• Slow sensor response after extended service life
• Emission control faults tied to B1S2 monitoring
• Rough drivability caused by inaccurate exhaust readings

Installation Notes and Tips

Verify the downstream B1S2 location before installation and confirm the connector, thread size, and harness length match the original sensor. Because this is a specific-fit oxygen sensor, it should be installed on the listed applications only. Inspect the exhaust bung threads and wiring routing before tightening the sensor to avoid damage during service.

Quality Assurance

NTK manufactures oxygen sensors with OE-level application coverage and tests them during production to support quality and reliability that meet or exceed original equipment specifications. The brand’s sensor-focused engineering and ceramic manufacturing background support consistent fit and function for import vehicle applications.
