NTK 24371 Air / Fuel Ratio Sensor - Upstream

NTK 24371 Direct Fit A/F Sensor Overview

NTK 24371 is a direct fit heated air/fuel ratio sensor built for precise upstream exhaust monitoring. It is engineered for the 2013-2014 Hyundai Genesis Coupe, Bank 1 Sensor 1, with OE-style fit, form, and function for the original sensor location.

As part of NTK’s Direct Fit 5-Wire A/F Sensor line, this sensor is designed for import and domestic coverage with application-specific connectors and harness length for a cleaner replacement on the Hyundai Genesis Coupe.

Key Features

• Direct fit replacement for the upstream Bank 1 Sensor 1 location
• Heated air/fuel ratio sensor for faster operating response
• 5-wire design for accurate exhaust feedback to the engine control system
• Specific fit construction for the 2013-2014 Hyundai Genesis Coupe
• 23.8 in. wiring harness length for application-matched routing
• 18.000 mm thread diameter with 0.38 in. thread length
• NTK part number 24371 for easy identification

Detailed Description

NTK 24371 is an OE-style air/fuel ratio sensor for the upstream position on the 2013-2014 Hyundai Genesis Coupe. It uses a heated, 5-wire configuration to deliver the signal the engine management system relies on for fuel control and emissions monitoring. NTK’s sensor manufacturing is centered on ceramic technology and OE application coverage, with testing performed during production to support consistent fit and reliable operation. This part cross-references DENSO Auto Parts 234-5044 for the same application.

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air/fuel ratio readings from the Bank 1 Sensor 1 location
• Rough idle or drivability issues tied to faulty exhaust feedback
• Failed emissions inspection caused by sensor response problems
• Slow sensor switching or degraded heater circuit performance

Installation Notes and Tips

Install NTK 24371 in the upstream Bank 1 Sensor 1 position on the Hyundai Genesis Coupe only when the vehicle matches the listed fitment. Verify connector style, thread diameter, and harness routing before installation. No mounting bracket is included. For best results, inspect the exhaust bung threads and clear any stored diagnostic trouble codes after replacement.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer with extensive OE application coverage. The brand’s direct fit sensors are produced with controlled ceramic technology and are tested during manufacturing to help meet or exceed OE specifications for fit and reliability.
