Show original supplier description
The Mazda Miata MX-5 Oxygen Sensor is designed as a direct-fit replacement for 1994-1997 1.8L models, specifically for Bank 1, located before the catalytic converter. This crucial sensor monitors the oxygen levels in your exhaust system, providing vital data to the ECU (Engine Control Unit) to maintain an optimal air-fuel ratio of 14.7:1. Proper functioning of this sensor is essential for preventing lean or rich conditions, which can lead to reduced engine performance, increased fuel consumption, and potential damage to the engine and catalytic converter. Constructed with premium materials, this oxygen sensor is built to withstand the harsh environment within the exhaust pipe, ensuring longer service life and reliability compared to common mass-produced units. Rspeed Oxygen Sensors are rigorously tested both on and off the track to meet OE specifications, aiming to enhance engine performance, lower emissions, and improve fuel economy. This direct-fit design eliminates the need for cutting or splicing, featuring an original-style plug-and-play harness for straightforward installation. It is manufactured in the OS5 Japanese type with a rounded hole and frontal tube, mirroring OEM specifications. This oxygen sensor is specifically for the 1994-1997 Mazda Miata MX-5 1.8L. It is important to note that this part is not compatible with 1998 Mazda models, as indicated by fitment information suggesting it "DOES NOT FIT YOUR 1998 Mazda."
