Key Features

Standard narrow band type Oxygen Sensors operate between 0 and 1 volts, and are only capable of accurately measuring a stoichiometric air/fuel ratio (e.g. 14.7:1). A richer or leaner condition results in an abrupt voltage change and is only useful for qualitative determination. Modern automobiles use "switch" like sensing at idle and part throttle to make small compensations in fuel delivery to keep the air/fuel ratio near 14.7:1.

Features/Benefits
Manufactured on OE production line
Bosch premium oxygen sensors for the aftermarket are produced on the same production line as our OE sensors

“True Direct Fit” Sensors
Bosch utilizes OE connectors, and all Bosch-made oxygen sensors also feature an OE-style harness. That means a continuous wire from connector to sensor
No cutting, no crimping, no splicing

Fast-acting heater system
Brings the oxygen sensor to operating temperatures more quickly to get the best performance out of the vehicle.

Double laser-welded stainless steel body
Fully submersible in water
Air-tight seal protects against contamination to ensure long life.

100% Exhaust testing
Every sensor is tested in simulated exhaust gas to ensure the highest quality
