NTK 24605 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Direct Fit Oxygen Sensor

NTK 24605 is a direct fit heated oxygen sensor built for specific downstream applications. It uses a threaded mounting design and a 4-wire configuration with a 26.75-inch harness for OE-style replacement on select Lexus and Toyota vehicles.

Key Features

• Direct fit design for specific applications
• Heated oxygen sensor with 4-wire construction
• Threaded mounting type with 18 mm thread diameter
• 26.75-inch wiring harness length
• OE-equivalent fit, form, and function

Detailed Description

NTK 24605 is engineered for downstream oxygen sensor service where precise signal feedback is required. Fitment includes select Lexus IS500, RC F, GS F, IS300, IS350, LS460, RC300, RC350, GS350, IS250, GS430, GS400, LS600h, and Toyota Prius, Celica, Sienna, and SC300 applications, with position-specific coverage for downstream right, downstream left, and downstream locations as listed. This part cross-references Bosch 13353 and DENSO Auto Parts 234-4139 for the same application. The NTK Direct Fit Oxygen Sensor line is built to streamline coverage while maintaining OE application technology and original-equipment-style performance characteristics.

What It Is Used For

• Replacing a failed downstream oxygen sensor
• Restoring accurate exhaust gas feedback to the engine control system
• Addressing check engine light concerns related to oxygen sensor performance
• Correcting drivability issues caused by degraded sensor response
• Maintaining emissions system operation on specific Lexus and Toyota models

Installation Notes and Tips

Verify the listed position, wire count, and threaded mounting specifications before installation. Match the downstream location exactly as shown in the fitment data, since this part is application-specific and not universal. Confirm connector routing and harness length against the original sensor before replacement.

Quality Assurance

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