Holley Chevy Camshaft Sync Kits
A cam sync signal is required to run sequential fuel injection, and Holley camshaft sync kits are ready to set the firing order for top performance. Available in a choice of kits for standard cam height small block and big block Chevys, as well as raised cam height big blocks, these Holley kits fit Jesel and other external, dry timing belt cam drive systems. They provide a plug-and-play cam position signal to Holley EFI systems, but are also compatible with any EFI system which can read a digital, square-wave cam input signal. All of the kits feature unique T-nut and bracket designs that allow for complete sensor adjustment from the outside of the bracket with a single jam nut. Let your ECU know which cylinder is number one in the firing order with a signal from Holley Chevy camshaft sync kits. Holley kits include: * 3-wire H all-effect sensor (8 to 20 V) * Anodized billet aluminum bracket * Mounting hardware * Mating connector * Stainless steel 1/4 in.-20 "flying magnet" screw with a high-temperature, rare-earth magnet

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

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.
