Denso Air/Fuel Ratio Sensors
Denso air/fuel ratio sensors (A/F sensors) were developed to measure air-to-fuel ratios under a wider range of driving conditions than oxygen sensors. A/F sensors, also known as wide-band oxygen sensors, send information to the engine management computer to make adjustments based on driving conditions. Their wider range and variable adjustments allow engines to burn fuel more efficiently and produce fewer emissions. As A/F sensor technology has evolved, Denso has been there every step of the way. From the first thimble-type sensors to today's heated, quick-response sensors required to meet ever more stringent emissions regulations, Denso has supplied OEMs with quality components and continues to innovate. Denso helped to develop this important technology and you can rely on Denso First Time Fit A/F sensors. Features and benefits of Denso air/fuel ratio sensors include: * Tarnish-proof platinum electrode provides longer life and maintains accuracy * Quick-response planar zirconia element quickly detects oxygen concentration * Measures air/fuel ratios from approximately 12:1 to 19:1 * Increased performance by mapping air/fuel ratios throughout the RPM range * Lower emissions by optimizing the air/fuel mixture * Reduces fuel consumption and maximizes catalytic converter life * First Time Fit design delivers the right part the first time

ACDelco GM Genuine Parts Oxygen Sensors
ACDelco GM Genuine Parts oxygen (O2) sensors are special feedback sensors on your vehicle's exhaust system and are GM-recommended replacements for your vehicle's original components. They measure the proportion of oxygen in exhaust gases, then using the measurement, the engine control module (ECM) can adjust the air/fuel ratio to near the optimal value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Choose the O2 sensor designed for your vehicle.

Denso Oxygen Sensors
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
