OE Heritage and Fitment Details

Delphi draws on more than 100 years of OE experience and supplier knowledge used by major automakers. That background is built into the ES20052 oxygen sensor, making it a practical replacement for vehicles that need accurate exhaust feedback and dependable connector and thread specifications. This part cross-references Bosch 13007 for the same application.

Compatible With 1996-2004 Acura RL, front right and front left; 1995-1999 Acura NSX, front right and front left; 1996-1998 Acura TL, front right and front left; 1991-1995 Acura Legend, right and left; and 1991-1994 Acura NSX, right and left. For Acura RL, Acura NSX, and Acura TL applications, confirm the exact sensor position listed for your vehicle before ordering.

What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the engine control system
• Slow sensor response from a worn heated O2 sensor
• Emissions test failures tied to faulty exhaust monitoring
• Rough idle or drivability issues caused by inaccurate exhaust readings

Installation Notes

Verify the connector shape, thread size, wire count, and sensor position against the vehicle application before installation. This ES20052 oxygen sensor is position-specific, so use the application tab or vehicle service information to confirm whether your Acura RL, NSX, TL, or Legend requires front left, front right, left, or right placement. Inspect the exhaust bung threads and wiring routing before tightening the sensor.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and engineering knowledge developed through long-term supplier experience with leading automakers. The ES20052 reflects that background with application-specific dimensions and sensor design for dependable replacement service.
