NTK 24784 Oxygen Sensor - Downstream or Downstream Front

Direct Fit Oxygen Sensor

The NTK 24784 is a direct fit heated oxygen sensor built for specific import applications with OE-equivalent design. It uses a threaded mounting style, a 4-wire layout, and a 17-inch harness for a clean replacement on supported Toyota and Lexus models.

Key Features

• Direct fit design for specific applications
• Heated oxygen sensor construction for faster operating response
• 4-wire configuration with 17-inch wiring harness
• Threaded mounting type with 18 mm thread diameter
• NTK 24784 part number for accurate ordering

Application Details

Compatible with 2016-2024 Toyota and Lexus applications listed in the fitment data, including Toyota Corolla, Prius, Prius AWD-e, Prius Prime, Sienna, and Highlander, plus Lexus RX350, RX350L, RX450h, and RX450hL. Fitment includes downstream and downstream front positions only, so the sensor should be matched to the exact vehicle and location shown in the catalog. This part cross-references Toyota OEM numbers 894650E210 and 8946547090 for the same application. The NTK 24784 is engineered for OE-style fit, form, and function across these supported vehicles.

What It Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel ratio feedback from a worn sensor
• Slow sensor response during closed-loop operation
• Replacement needs for a damaged threaded sensor assembly
• Fitment issues when an exact direct-fit sensor is required

Installation Notes

Verify the vehicle year, model, and sensor position before ordering. Match the connector style, wire count, harness length, and thread diameter to the original sensor. Because this is a specific-fit oxygen sensor, installation should follow the exact downstream or downstream front application listed for the vehicle.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. As part of the NGK family and a major OE oxygen sensor supplier, NTK focuses on fit, form, and function for direct replacement applications.
