Tell me what you guys think. Its nice how this can double as your stock narrow band for normal ECU operations. The only thing that worries me is the sensor's resistance (or lack thereof) to leaded race gas. When your spending $200+ on an O2 sensor, you want it to last. Especially when you can buy a Denso narrowband lead resistant O2 sensor for $80.

An 8 second Buick guy has mentioned that he's run the same NTK sensor for 5 years on VP 116.

I've only heard of a couple failing due to race gas, I think its long life is due to the massive heater these things have on them.

That's good news. Thanks for the info, Eric. I may just have to pick up one of these suckers.
