Engine knock is one of the most unwelcome problems to plague a vehicle. When your ignition timing becomes faulty, the results are felt unless corrected through a sensor. Chevrolet Performance knock sensor wiring harnesses should be used when replacing those key sensors, providing fresh OEM wiring and grommets. The harness units are available for over a hundred submodels from makers such as Chevrolet, GMC, Cadillac, Pontiac, Buick, and Hummer.

ACDelco GM Genuine Parts manifold absolute pressure sensors measure the intake manifold pressure, and are GM-recommended replacements for your vehicle's original component. The MAP sensor is a part of the fuel and engine management system. Its signal is used by the engine control module along with the throttle position sensor to calculate the amount of air entering the engine so that the correct amount of fuel is injected for optimum combustion. GM Genuine Parts manifold absolute pressure sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

The little devil in you will enjoy tormenting the competition with Davis Unified Ignition extreme Screamin' Demon coils. They allow you to widen your plug gaps up to a whopping .065 in. You get an intense spark through the entire rpm range to keep you "screaming" down the road without a loss of power. And your spark plugs stay cleaner longer! The brass terminals of these coils are more conductive than stock aluminum and resist corrosion longer, too. Demon coils are hot stuff and you'll need a better-than-stock set of wires to deliver that hotter spark to your plugs. So, turn up the heat on performance with Screamin' Demon coils from Performance Distributors.

ZZPerformance offers high-voltage coil packs for a wide range of vehicles—including many Chevrolet, Cadillac, Pontiac, Buick, and Oldsmobile models from the early 1990s and up. The coil packs are available in different styles for various applications. Here are further details: * Model HVCP-14T: Upgrade your Volt/ELR ignition coil for improved performance and economy! The GM Voltec platform was designed around it's battery/hybrid system, but the internal combustion system was a budget solution—and the factory coil does not maximize the performance and efficiency of your engine. ZZP's high-voltage coil pack has improved core material, tighter coil winding, and higher voltage. No ECU calibration needed. * Model HVCP-38V2: These high-voltage coil packs will supply a stronger spark, which allows you to run a larger gap that will improve fuel economy, drivability, and HP capability. Not an earth-shattering difference but a small gain. Definitely well worth the upgrade if you're replacing your coils. --- Torque spec: 25 inch pounds --- No returns on electrical items. --- Sold in a set of 3. --- These fit GM 3800 W-Body and H-Body cars, including L67, L36, L32, and L26 * Model HVCPLSSQ8: After the resounding success of ZZP's round-style LSx ignition coils, ZZP now offers this square style. These coils produce on average 15 percent more spark—and have dyno-tested "before and after" results netting 4 to 5 whp gains on a naturally aspirated LS vehicle. Turbocharged and supercharged vehicles have netted 10+ whp gains and 15+ percent more spark than stock. Very impressive numbers for coils, better than OEM! This set of 8 coils will fit in place of the stock coils and connect directly to the factory connectors. Once installed, you'll have the power and performance of higher energy ignition. The increased spark energy and voltage help improve the combustion process of the fuel mixture to create a more efficient burn. This results in improved throttle response, smooth idle, and quick starts, plus increased high-RPM performance! The coil packs also work fine for totally factory/stock vehicles. Fits 4.8, 5.3, 6.0, 6.2 and 7.0L. (Note: There are many variations of LS coils even within the same make and model year, so please check your vehicle to see if you have the square style. These replacements will not fit vehicles with the round style coil. The connectors and the way they mount are different, so you have to verify they look like the ones pictured.)

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.

Standard Motor Products MAP sensors are direct, high-quality replacements for your vehicle's worn, damaged, or malfunctioning manifold absolute pressure sensor. These sensors accurately produce voltage or frequency as manifold pressure changes, and the computer uses this information to measure engine load so that the ignition timing can be advanced and retarded as needed. On engines with a speed density type of fuel injection, the MAP sensors also help the PCM estimate airflow. Malfunctioning MAP sensors can often cause problems such as an intermittent check engine light, hesitation when accelerating, elevated emissions, and poor engine performance. Keep your vehicle in top operating condition with Standard Motor Products MAP sensors.

Standard Motor mass airflow sensors are higher quality, precision alternatives to remanufactured models. MAF sensors measure the amount of airflow entering the intake manifold and must communicate clearly with your vehicle's Engine Control Module (ECM). Remanufactured components with debris from prior use can hinder this communication and cause your vehicle to experience drivability issues. With many new—not remanufactured—MAF sensors in the Standard lineup, they cover more than 90 percent of all MAF-equipped vehicles, and all are airflow-calibrated to ensure accuracy. SMP-manufactured sensors are designed with improvements such as thicker walls, upgraded components, and a custom-designed platinum RTD sensor. The result is a line of MAF sensors that provide highly accurate readings and precise airflow output under all operating conditions. Order the model designed for your car, truck, or van.
