Denso Upstream AFR Air Fuel Ratio Sensor for Mercedes-Benz E550 5.5L V8 bs
Status: In Stock
Condition: New
The DENSO Air/Fuel Ratio Sensor (AFR), also known as a wide-band oxygen sensor, is one of the most sensitive components on your car engine. The sensor measures the air-to-fuel mixture in the exhaust stream under a wide range of driving conditions and sends information to the engine management computer to make adjustments based on driving conditions. Engines today may use as many as four sensors, which monitor not only exhaust gas-oxygen content, but catalytic converter efficiency as well. In order to perform these functions properly, the sensors must adhere to OE standards within incredibly close tolerances. DENSO First Time Fit oxygen sensors are designed to meet those tolerances and more. Symptoms of a malfunctioning or poorly calibrated air/fuel ratio oxygen sensor include a triggering of the check-engine light, bad gas mileage, and a rough idle. DENSO has been a key player in the development of the highest-grade oxygen sensors—from the first thimble-type to the heated, quick-response sensor. You can rely on DENSO for decades of engineering expertise to provide a premium replacement air/fuel ratio sensor.
- REDUCE FUEL CONSUMPTION, PRODUCE LESS EMISSIONS, AND MAXIMIZE CATALYTIC CONVERTER LIFE by keeping the air-fuel mixture at an optimum ratio
- PROVIDE MUCH FINER CONTROL OF AIR/FUEL MIXTURES IN VARIED OPERATING CONDITIONS and enable the fuel injection and engine timing to work more efficiently
- MAINTAIN ACCURACY AND LONGEVITY: tarnish-proof platinum electrodes extend the life of the sensor while DENSO’s exclusive aluminum-oxide trap layer prevents damage to the electrode
- QUICKLY DETECT OXYGEN CONCENTRATION: the quick-response planar zirconia element speeds reaction times while the double-protection cover protects the element against silicone and lead poisoning
- PREVENT CORROSION: corrosion-resistant stainless steel construction, rugged and watertight housing, and a porous PTFE filter prevent contaminants from seeping into the casing
