Bosch Premium Universal Type Oxygen Sensors
Worn-out sensors can cause engine performance problems and premature catalytic converter damage. Bosch premium universal type oxygen sensors with OE SmartLink produce precise output in proportion to the air/fuel ratio, due to a sophisticated sensing element. These premium sensors also use a patented connector system, which allows them to be added to an existing OE sensor harness. Keeping a properly functioning oxygen sensor in your vehicle saves money on fuel cost and is good for the environment, too!

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

Standard Motor Camshaft Position Sensors
Don't take chances with an old, questionable, or malfunctioning camshaft position sensor that can leave you stranded. Camshaft position sensors read the camshaft position and relay this information to your vehicle's ECM. This information is required for functions such as initiating injection on sequential injection engines, the trigger signal for the magnet valve on pump valve injection systems, and for cylinder-specific knock control. Standard Motor Products replacement cam position sensors are designed to exceed OEM specifications for accurate, reliable, maintenance-free operation. Trust your vehicle's engine management system needs to Standard Motor Products.

Denso Camshaft Positioning Sensors
Denso camshaft positioning sensors detect camshaft rotation during the engine-combustion cycle. Denso produces both magnetic resistant element (MRE) type and magnetic pick-up (MPU) type sensors. Features and benefits of Denso camshaft positioning sensors include: * Denso MRE sensors have a pair of MREs on an integrated circuit (IC) chip; this unique design is extremely accurate, even just after an engine is started * The molded IC chip is installed inside a cylindrical magnet so it is positioned closer to the gears that rotate with the camshaft--this design is almost 10 times more sensitive than Hall element type sensors * Denso uses a polyphenylene sulfide resin coating over the molded IC chip and cylindrical magnet for greater strength and superior resistance to substances like fuel, engine oil, and emission byproducts

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.
