ACDelco GM Genuine Parts Knock Sensors
ACDelco GM Genuine Parts knock sensors are the GM recommended replacement for the vehicles original component. They monitor the engine for pinging or spark knock. The sensors create a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion. The engine control module then uses that signal to adjust the ignition timing and air/fuel mixture. These GM Genuine Parts knock sensors have been manufactured to fit your GM vehicle, providing you with the same performance, durability, and service life you have come to expect from General Motors.

ACDelco GM Genuine Parts Ignition Coils
ACDelco GM Genuine Parts ignition coils are the true OE parts installed during production or validated by GM, for GM vehicles--designed, engineered, and tested to rigorous standards and backed by General Motors. They increase electrical system voltage to help ignite the air/fuel mixture as the starting and charging system starts the engine, maintains the battery's charge, and provides power to the electrical accessories while the engine is running. GM Genuine Parts ignition coil uses pure copper windings to improve durability and provide higher resistance to internal shorts and dielectric breakdown. Because the number and shape of the laminations determine the output characteristics of an ignition coil, ACDelco ensures that the silicone steel plates surrounding the coil correctly match the original part size and number. Since steel laminations work best when they are new, shiny, and clean, ACDelco laminations are coated to hinder corrosion and many feature molded plastic protection to help ensure that nothing is exposed.

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

Holstein Parts Knock Sensors
The knock sensor is able to detect mechanical stress and produces a voltage when the car knocks or pings. Under heavy acceleration, it sends signals to the ECU and the ECU retards the ignition timing to compensate for the knocking, which in effect protects the pistons and rings from damage. Knocking also occurs when using low-grade fuel and having the knock sensor allows you to use different grade fuels without causing engine damage. Holstein Parts focuses on using only the highest quality materials, manufactured to exacting standards for an aftermarket product that is truly built to match or exceed the OE part. Holstein Parts knock sensors line has superior coverage for domestic and import applications.
