OXYGEN SENSOR 4 WIRE DIRECT FIT H

The DENSO Oxygen Sensor, also known as an O2 sensor, showcases superior engineering for optimal performance. Located either upstream or downstream of the catalytic converter, it monitors the air-fuel mixture under idle, moderate acceleration, and cruise conditions. The superior design of this oxygen sensor maximizes engine performance while reducing fuel consumption and harmful emissions. It adheres to OE standards, featuring a damage-tolerant stainless steel housing, a double cover protecting the ceramic element against silicone and lead poisoning, and a porous PTFE filter allowing atmospheric oxygen to enter without water or engine grime.
