Bosch 13120 oxygen sensor for the 1993-1995 Ferrari 348 Spider V8 3.4L and other vehicles sends air-fuel-ratio readings to the ECU. This Bosch O2 sensor is a heated, narrow-band, switching-type unit that helps the ECU keep combustion stable and emissions down.
- Narrow-band switching-type sensor that gives the ECU air-fuel-ratio feedback
- Integrated heater element brings the sensor to operating temperature in under 10 seconds
- Metal housing and TSP coating resist vibration, corrosion and contamination in exhaust up to 1,880°F
- Pre-applied conductive anti-seize on the threads and connectors made for quick installation
Quick facts
- Part: Bosch 13120 oxygen sensor
- Fits: 1993-1995 Ferrari 348 Spider V8 3.4L and other vehicles
- Position: Upstream, upstream left, upstream right
- Material: Metal (housing)
- Condition: New
An aging oxygen sensor can bring a check engine light, a rough idle or worse fuel economy. These signs alone don't prove the sensor is at fault, since a vacuum leak can upset the air-fuel ratio too.
Fits
The 1993-1995 Ferrari 348 Spider V8 3.4L, the 1992-1994 Ferrari 512 TR H12 4.9L and the 1993-1994 Ferrari 348 GTB V8 3.4L all take this sensor, and so do other vehicles. Those Ferraris take two sensors apiece, and this listing is one sensor. If your car isn't named here, look it up in the "Vehicles it fits" section before you order.
