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

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.

NTK is the world's leading supplier of OEM oxygen sensors. They're individually tested to ensure the highest level of quality and reliability—designed to continuously detect the composition of exhaust gases. As the output from the sensors changes, the ECU instructs the fuel mixing system to alter the mixture. This ensures that the air/fuel mix is always correct and promotes efficiency. A new NTK oxygen sensor can help lower emissions, improve fuel mileage and engine efficiency, and extend catalyst life. These components meet or exceed OE specs and are equipped with waterproof, factory-fitted connectors to ensure a perfect fit every time. Order the model recommended for your vehicle.

MSD offers replacement wiring harnesses for the Power Grid Dual NTK wideband oxygen module—a dual channel air/fuel ratio (AFR) system designed to interface with the Power Grid (P/N 7730) to monitor and record the AFR of internal combustion engines. The oxygen sensor module is capable of measuring AFR as low as ? = 0.5 (7.35:1 gasoline AFR equivalent). The AFR range is configurable using the MSDView software in conjunction with the Power Grid Controller (P/N 7730). Excellent MSD range of the NTK sensor gives each unit the ability to accurately monitor AFR's even on alcohol cars. The MSD wideband oxygen sensor module also provides a 0.5-4.5 VDC analog output proportional to the AFR. This analog output can be sent to a gauge or a data acquisition system. A dual-color LED provides the system status at a glance. (To provide accurate backpressure compensated AFR readings on turbocharged applications, the addition of an Exhaust Pressure Module, part number 7767, is required.) MSD can provide a replacement main harness, sensor 1 harness, or sensor 2 harness for your application. Order the model needed to restore proper performance to your vehicle.
