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

Centric Premium High-Carbon Brake Rotors
Centric premium high-carbon brake rotors feature advanced metallurgy that greatly reduces the possibility of pad squeal, especially with higher friction brake pad compounds. Proprietary molybdenum and chromium alloys resist rotor cracking during high performance use or repeated stop situations and increase friction--improving brake performance and stopping power. E-coat, Centric's advanced, electro-static, black finish, is applied to all non-friction surfaces of these high-carbon alloy rotors to protect the cooling vanes and mounting surfaces from rust. When it comes to your ride's brake system, don't settle for mediocre parts. Improve your brakes with Centric premium high-carbon brake rotors and you'll have no regrets. Additional features include: * Symmetric vane castings for increased strength and stability; process used by OE manufacturers * Non-directional finish for improved rotor and pad break-in * Double disc-ground friction surface finish virtually eliminates run-out and disc thickness variation issues * Mill-balanced to a tolerance of less than 2 oz.-in. for smooth operation at all speeds
