Mazda MX-5 Miata O2 Sensor for California - New York 1999 - 2000 1.8 after Exhaust Manifold - Direct Fit Replaces Mazda BP4X-18-861C-9U
This Oxygen Sensor for is California and New York Emissions 1999-2000 1.8L Mazda MX-5 Miata. Bank 1: replaces Mazda BP4X-18-861A-9U the second o2 which is located in the just behind the exhaust manifold. Harness mounted back of the engine.
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 of14.7.1.
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 02s are tested against the sensor's function parameters to guarantee the highest quality and stability for even the most discerning Miata owners.
Unlike troublesome universal units, ours does not require any cutting or splicing as all our Miata o2 Sensors feature original style plug and play harnesses. Additionally, we build all O2 Sensors feature OE Type connectors, in the rounded hole, frontal tube, Japanese type just like the OEM units that where factory equipped with you Mazda MX-5 Miata.
