NTK 24176 Oxygen Sensor - Upstream

Direct Fit Oxygen Sensor for Mazda Miata

NTK 24176 is a direct fit oxygen sensor for 1990-1993 Mazda Miata upstream applications. Built as a specific-fit, threaded sensor with a 21.75-inch wiring harness, it supports accurate air/fuel ratio feedback where the engine management system relies on a non-heated O2 sensor signal.

Key Features

• Direct fit oxygen sensor for specific applications
• Fits 1990-1993 Mazda Miata, upstream
• Non-heated sensor design with 1-wire configuration
• Threaded mounting type with 18 mm thread diameter
• 21.75-inch wiring harness length for OE-style routing
• NTK part number 24176

Product Details

NTK 24176 is part of the Direct Fit Oxygen Sensor line, created for straightforward replacement in applications that require OE-style fit, form, and function. NTK is known for ceramic sensor manufacturing and OE application coverage, and this sensor is produced and tested to meet or exceed original equipment specifications. For Mazda Miata owners searching for a 1990-1993 Mazda Miata upstream oxygen sensor or an OE replacement oxygen sensor for Bank 1 Sensor 1 air/fuel ratio control, this part provides the correct configuration for the listed application. This part cross-references Bosch 12113 for the same application.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Incorrect air/fuel ratio feedback at the engine control system
• Rough idle or drivability concerns tied to sensor signal loss
• Failed emissions testing caused by a worn upstream sensor
• Slow or inaccurate sensor response in the exhaust stream

Installation Notes and Tips

Install this sensor in the upstream position specified for the vehicle application. Verify the 18 mm threaded mounting point, 1-wire non-heated configuration, and harness routing before installation. Confirm connector style and wire length against the original sensor on the Mazda Miata to ensure proper fitment and routing away from heat sources.

Quality Assurance

NTK manufactures oxygen sensors with OE-focused engineering and extensive production testing for quality and reliability. As part of the NGK family of products, NTK supports import and domestic applications with direct-fit sensor coverage and original-equipment-level application data.
