Denso air/fuel ratio sensors (A/F sensors) were developed to measure air-to-fuel ratios under a wider range of driving conditions than oxygen sensors. A/F sensors, also known as wide-band oxygen sensors, send information to the engine management computer to make adjustments based on driving conditions. Their wider range and variable adjustments allow engines to burn fuel more efficiently and produce fewer emissions. As A/F sensor technology has evolved, Denso has been there every step of the way. From the first thimble-type sensors to today's heated, quick-response sensors required to meet ever more stringent emissions regulations, Denso has supplied OEMs with quality components and continues to innovate. Denso helped to develop this important technology and you can rely on Denso First Time Fit A/F sensors. Features and benefits of Denso air/fuel ratio sensors include: * Tarnish-proof platinum electrode provides longer life and maintains accuracy * Quick-response planar zirconia element quickly detects oxygen concentration * Measures air/fuel ratios from approximately 12:1 to 19:1 * Increased performance by mapping air/fuel ratios throughout the RPM range * Lower emissions by optimizing the air/fuel mixture * Reduces fuel consumption and maximizes catalytic converter life * First Time Fit design delivers the right part the first time

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.

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

Bully Dog has always been there to make your vehicle perform the way you want it with their programmers and tuners for gas and diesel powered trucks and SUVs. One of the problems with all modern-day vehicles is the throttle is operated electronically, not by a cable, so the vehicle computer dictates how much throttle to give. Bully Dog Thruster throttle boosters are here to help. This simple to use plug-and-play system gives you the throttle you want when you want. Installation is simple and can be removed anytime. Simply unplug the factory harness from the pedal, plug the Bully Dog Thruster throttle booster into the pedal and the other side into the vehicle harness. A rotary switch allows you adjust the sensitivity on-the-go so you can dial in the throttle you want. Bully Dog Thruster throttle boosters will amaze you with the performance gains you will achieve with this small device.

Beck/Arnley ABS speed sensors supply information regarding wheel speed to the ABS computer. They are often located at each wheel hub/rotor on 4-wheel disc systems. Alternatively, on rear drum applications, you'll usually find them mounted on the differential housing. Under braking, if wheel speeds are unequal, indicating wheel lockup, then the computer modulates the anti-lock feature until the speeds are equal again.
