Denso Air/Fuel Ratio Sensors
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

Wilwood Floor-Mount 2-Pedal Assemblies
Wilwood has engineered two reverse floor-mount brake pedal assemblies, one with a standard bias adjuster balance bar and the other with a precision Tru-Bar. Both models incorporate an adjustable clutch pedal assembly. Wilwood floor-mount 2-pedal assemblies feature lightweight aluminum frames with high-strength reinforced I-beam style forged pedal arms and stainless steel foot pedal pads. The pedal heads adjust vertically to fine-tune the pedal ratio (5.25:1 to 6.00:1) for more feel or less pedal effort. The non-skid waffled pedal pads can be laterally adjusted for driver preference. A clutch and two brake master cylinders (sold separately) mount to the assemblies with the adjustable balance bar or the friction-free, trunnion-based adjustable Tru-Bar balance bar, providing front-to-rear brake bias fine tuning. Both the balance bar and Tru-Bar incorporate a positive detent stop every full turn to maintain adjustment position and can be locked in place with the included jam nut, or used with an optional remote knob for quick on-track adjustments. Select the Wilwood 2-pedal assembly with the brake pedal option desired. Key features and notes: * Adjustable pedal ratio * Adjustable foot pads * Forged aluminum pedal arms * Adjustable clutch stop * Wilwood's own black e-coat finish * Triple high-strength steel master cylinder mounts -- Traditional flange mounts at a 45-degree angle -- Accommodates three Wilwood compact remote master cylinders (sold separately) * Balance bar utilizes a pin and clevis pushrod attachment system -- Ensures the smallest possible misalignment angle for bind-free operation through the entire range of travel * Tru-Bar pedals utilize a fixed trunnion bearing in the pedal arm with spherical rod-end bearing pushrod attachments -- Reduces compliance and friction for more accurate brake feel -- Pedals utilize the same chassis and master cylinder mounting as Wilwood balance bar-style pedals

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
