Placement On Vehicle

In vehicles exhaust system after the catalytic converter

Brand

Denso

Fitment Type

Ceramic based heating element

Function: This sensor is designed to detect the amount of oxygen in the exhaust stream, monitoring the air/fuel mixture during various engine conditions (idle, acceleration, cruise). It helps maintain an optimum air/fuel ratio for reduced emissions, improved fuel efficiency, and maximized catalytic converter life. Construction: It is constructed from high-quality materials, including stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum, and ceramics. Protection: It features an exclusive aluminum-oxide trap layer to protect the ceramic element from silicone and lead poisoning, which can damage the platinum electrode. A double protection cover helps maintain proper unit temperature for quicker response times and further protects the ceramic element from contamination. Fitment: The (contact info removed) is a direct-fit, specific oxygen sensor, meaning it is designed to be an exact replacement for certain vehicle applications, such as downstream positions in 1(contact info removed) Acura EL, 1(contact info removed) Honda Civic, and 1(contact info removed) Acura Integra. Specifications: It is a 4-wire, heated oxygen sensor with a male connector and a threaded mounting type, featuring a thread diameter of 0.708 inches and a wire length of 12.99 inches. Quality: Denso states that its "First Time Fit" oxygen sensors, including this model, meet or exceed both the needs of sophisticated modern engines and the original equipment tolerances set by vehicle manufacturers
