Leaded Fuel and O2 Sensor
 

What sensors are folks having "longer term" (longish?) success with?

I'm using NTK sensors from MAD racing with a Holley ECU.

Thank you

Is someone is making a leaded fuel compatible sensor now? My understanding is that they were not compatible. I found out the hard way by blending 100 avgas and 91 octane fuel. It took around 500 miles but it finally corrupted the O2 sensor.

I have seen this one also......but no direct experience.
