Caspers Electronics knock sensor wiring harnesses with LS1 cam sensor adapter allow the cam sensor used on the front of an LS2/3/4/7/9 engine to be plugged into the LS1 cam sensor connector located at the back of the intake manifold. They are ideal for LS2/3/4/7/9 motor conversions and are compatible with the PCM harness in LS1/LS6 vehicles. Additionally, they include a knock sensor extension, which allows the single-wire LS1 knock sensors located on top of the LS1 manifold to be relocated on both sides of the LS2-series block, using the factory LS1 engine harness. The Caspers Electronics knock sensor wiring harnesses with LS1 cam sensor adapter have the correct length and thermal protection required when routing near hot engine components.

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.

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

APR boost tap adapter kits are modular systems that plug directly into the intake manifold and make several configuration options available. APR modular boost tap and PCV bypass systems feature a tap used for referencing boost or vacuum from the manifold, a cap (if this feature is unneeded), a T-junction to allow for multiple boost and vacuum references, and a "no buzz" restrictor pill for proper manual boost gauge operation. The systems also include a threaded PCV plug, allowing the PCV system to operate as intended by the OEM, as well as blocked off, if needed, for a specific PCV or catch-can setup. Temporarily installing the threaded plug also allows for quick diagnosis of the PCV valve for boost leaks. APR's innovative and modular design ensures operation with all boost, vacuum, and PCV system combinations, leaving no compatibility worries for future configurations. Key features: * Provides manifold pressure and vacuum * Supports multiple connections * Blocks off front PCV is so desired * Includes all accessories * Plug-and-play install

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.
