Delphi® Oxygen Sensor ES20421

Delphi Oxygen Sensor are featured as follows:

• Resists high temperatures, vibration and wire corrosion to protect signal accuracy, and prolong life.
• Fastest light-off times in the industry to cut down on cold-start emissions.
• Fuel economy is improved compared to old sensors.
• Sensor coating protects against contaminants which can trigger "check engine light" and cause an early failure of the sensor.
• Delphi's planar technology replaces the older, dated conical sensor design.
• The sensor validation process includes different fuel types, including ethanol blends such as E85.
• OE testing included 150,000 miles with 2,000 hours of severe thermal exposure.
• These sensors are easy to install for a quick upgrade.
• "Dry to touch" proprietary anti-seize compound for faster, no mess installations for mechanics and DIYers.
• The sensor design allows for up to 482 vehicle applications, which reduces part duplicity and inventory shortages.
• Meets OE specifications where connectors and wire lengths are a factor for fitment.

The Delphi Oxygen Sensor ES20421 is a high-quality, durable sensor that withstands high temperatures, vibration damage and wire corrosion. It has a patented sensor construction and design along with one-of-a-kind coating for shielding contaminants that can cause "check engine lights" as well as premature sensor breakdown. Additionally, this sensor uses Delphi planar technology which offers the industry's fastest light-off times for reducing cold-start emissions as well as aging sensors' improved fuel economy. This product has been validated for all fuel types including E85 or ethanol blends and subjected to 150,000 miles of use plus 2,000 hours of severe thermal testing. This sensor is easy to install and helps reduce emissions, which helps clean our air!

Delphi is a respectable brand within the automotive industry for over 100 years. They started to making the first automobile radiator (in 1911), the first vehicle air conditioning system (in 1954), and the initial car heater (in 1929). As a leader in OE-quality products, Delphi manufactures efficient and reliable compressors that are utilized in more than 3,400 applications in North America. The company continues to maintain its focus on quality and innovation by manufacturing most of its products within North America.
