Mazda MX-5 Miata O2 Sensor for Miata 2001-2005 1.8 Front Pre Cat - Direct Fit BP6F-18-861B-9U8
Oxygen Sensor for 2001-2005 1.8L Mazda MX-5 Miata. Bank 1: replaces Mazda BP6F-18-861B-9U the first O2 which is located at exhaust manifold.
The oxygen sensor is a critical component of the automotive fuel injection system; it constantly measures the oxygen content in the exhaust gas and helps the ECU (Vehicle Computer) ensure optimal engine operation at an industry standard of 14.7.1.
Most importantly, too much oxygen in air/fuel ratio means the engine is running lean which is less than optimal causing reduced engine performance and damaging detonation. Oppositely, if there is too little oxygen in the ratio it means the engine is running rich and wasting excessive fuel and creating excess emission. Both conditions may shorten the lifespan of a vehicle's engine and catalytic converter.
This Oxygen Sensors are the result of rigorous testing on and off track to produce Oxygen Sensors that operate consistently at OE specifications; as such they increase vehicle's engine performance, lower vehicle emissions, and improve vehicle's fuel economy. To ensure longer sensor lifecycles and vehicle safety, every O2 sensors is produced with premium materials that protect the sensor against the harsh environment inside of the exhaust pipe, which cause premature sensor failure in common in mass produced units. In addition, all of our 02s are tested against the sensor's function parameters to guarantee the highest quality and stability for even the most discerning Mazda MX-5 Miata owners.
Unlike troublesome universal units, ours does not require any cutting or splicing as all our Mazda Miata O2 Sensors feature original style plug and play harnesses. Additionally, we build all O2 Sensors in the Rounded hole, frontal tube, OS5 Japanese type just like the OEM units that where factory equipped with your Mazda Miata MX-5.
