Detailed description

NTK 27019 is part of NTK’s Direct Fit 5-Wire A/F Sensor line, engineered for exact application coverage rather than universal adaptation. NTK draws on its oxygen-sensor manufacturing background and OE application technology to deliver fit, form, and function aligned with original equipment requirements. This part cross-references DENSO Auto Parts 234-5176 for the same application.

Compatible with 2015-2017 Ford Mustang, upstream right. For buyers searching for a Ford Mustang air/fuel ratio sensor or an upstream right replacement, NTK 27019 provides a direct-fit solution for the listed vehicle application.

What it is used for

• Replacing a worn or slow-responding air/fuel ratio sensor.
• Addressing sensor-related drivability or fuel-trim faults.
• Restoring proper feedback to the engine management system.
• Correcting issues tied to an incorrect or failing upstream sensor signal.

Installation notes and quality

Install only on the listed application and verify thread size, harness length, and connector match before installation. The sensor is specific fit, so it should be matched to the exact vehicle and position shown in the fitment data.

NTK states that its oxygen sensors are extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. NTK 27019 is supported by that OE-focused manufacturing approach.
