They aren't accurate at reading the air/fuel ratio when the car is at high load (accelerating) or idle. Therefore, they're not very useful for tuning an engine.
The wide band oxygen sensor has a different construction that allows it to be accurate for a much wider range of air/fuel ratios. With this sensor, you can measure and tune an engine for optimal operation under all driving conditions.

Jaay, congradulations on the baby. Kids are great. I have 4 myself.
Anyway, I too am new to Boxsters and a lot of this tecnical jargon. Though I have done a lot of my own basic car maintenence and repairs, I have never done any performance mods to any of my cars.
Let me see if I can get this streight:
- This gets installed on the exhaust
- I presume it somehow gets hooked into the cars computer?
- It can help the cars computer to improve air/fuel ratios
- It can improve performance and I would also presume efficiency
Anything else missing?
