why do you need an O2 sensor? if yours is bad, cant you just disconnect? usually, it only runs the car open loop on most cars at the track. is yours different? just checking as you might be ok to race it without it functioning correctly. what car are we talking about?

If it is the upstream sensor it probably won't run right. On one of my Jags, the wife got a check engine light. At first it wasn't noticeable, but over time the car lost power as the ECU uses it for tweaking engine parameters. New O2 sensor fixed it right up. This is a 2003 MY car, I'm sure the GT4 here is more sophisticated.

It used to be that O2 sensors didn't affect performance much, only emissions, but it does not seem so on modern power plants. IIRC, a bad o2 sensor used to make a motor run better because it richened the mixture, but not anymore.

This is the ore cat sensor and ya a new car needs to run right may go into low performance mode.

Cross reference the generic part and see if a local flac has it.

I think it is Bosch 17331

Seems to have been a fluke that happened while putting it on the trailer. It ran like a champ today.

Broken car on a track day sucks. Broken car at COTA has an extra sting. Glad it worked out for you.
