Direct-Fit Oxygen Sensor

NTK 24050 is a direct-fit heated oxygen sensor built for specific import applications. It uses a threaded mounting design and a 4-wire configuration with a 29.5-inch harness length for a precise replacement setup.

Key Features

  • Heated oxygen sensor for faster operating response.
  • Specific-fit design for direct replacement applications.
  • 4-wire construction with threaded mounting.
  • 18 mm thread diameter for the listed applications.
  • NTK 24050 is backed by OE-focused engineering and manufacturing.

Detailed Description

NTK 24050 is engineered as a direct-fit oxygen sensor for select Mitsubishi 3000GT, Mitsubishi Diamante, and Dodge Stealth applications. Fitment includes upstream right locations with Bank 1 Sensor 1 and California emissions notes where listed, making this a targeted replacement for vehicles that require the correct sensor response and connector layout. The heated design helps the sensor reach operating temperature efficiently, while the specific-fit format supports a clean replacement on the listed applications. This part cross-references Bosch 15581 and DENSO Auto Parts 234-4631 for the same application.

What It Is Used For

  • Replacing a failed oxygen sensor that triggers check engine light concerns.
  • Restoring air-fuel ratio feedback for engine management.
  • Addressing drivability issues tied to inaccurate exhaust oxygen readings.
  • Correcting emissions-related faults on listed Mitsubishi 3000GT, Mitsubishi Diamante, and Dodge Stealth applications.

Installation Notes and Tips

Verify the vehicle year, engine configuration, and emissions notes against the fitment list before installation. Confirm the upstream right location, Bank 1 Sensor 1 designation, and threaded mounting style match the original sensor. Use the 29.5-inch harness length and 4-wire layout as reference points when comparing the removed part to NTK 24050.

Quality Assurance

NTK is part of the NGK family of products and is a major original equipment oxygen sensor supplier. Each sensor is extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications.
