Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mix

Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors).

Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more.

Key features and benefits of Denso Oxygen Sensors include:

* Robotic laser welds
* Porous PTFE filters block efficiency-robbing contaminants
* Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling
* Rugged, watertight stainless steel housings resist corrosion and contamination
* Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode
* Refined zirconia elements improves sensor response
* Superior design maximizes engine performance while reducing fuel consumption and harmful emissions
* First Time Fit design delivers the right part the first time
