Delphi ES10927 Front Oxygen Sensor

The Delphi ES10927 is a front oxygen sensor built for specific Hyundai and Kia applications from 2003-2009. It uses a 5-wire design, square connector shape, and 18 x 1.5 mm thread size for OE-style replacement on the vehicles listed below.

Key Features

• Front oxygen sensor for emission control systems
• 5-wire configuration for the specified application
• Square connector shape for direct-fit electrical connection
• 18 x 1.5 mm thread size
• 460.0 overall length
• Package contents include the oxygen sensor and instruction sheet
• Delphi ES10927 part number for catalog matching and service lookup

Application Details

Compatible with 2003-2009 Hyundai Elantra front applications, 2004-2009 Kia Spectra front applications, and 2005-2009 Kia Spectra5 front applications. This Delphi ES10927 oxygen sensor also covers 2004-2008 Hyundai Elantra front applications, plus 2004 Hyundai Elantra front with California Emission System and without California Emission System from 07/01/2003, and 2009 Hyundai Elantra front to 04/03/2009.

Delphi builds OE replacement parts using more than a century of original-equipment experience and knowledge gained from supplying major automakers. That background is reflected in the ES10927’s application-specific design for Hyundai Elantra, Kia Spectra, and Kia Spectra5 front sensor locations.

This part cross-references Bosch 15646 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings
• Reduced fuel economy caused by faulty sensor feedback
• Emission test failures tied to front sensor issues
• Slow or inaccurate exhaust oxygen signal response

Installation Notes

Verify the front sensor location, connector shape, wire count, and thread size before installation. Compare the existing sensor length and connector style to the Delphi ES10927, and follow the included instruction sheet during replacement. Confirm the vehicle’s emission configuration and build date where noted in the fitment data, especially for 2004 and 2009 Hyundai Elantra applications.

Quality Assurance

Delphi OE heritage and supplier experience are built into this aftermarket oxygen sensor for application-specific fitment and service reliability.
