air / fuel sensors

I am looking to replace my air fuel sensors. Rockauto has the NTK (I believe OEM type, correct me if I am wrong) sensors for about $125 per plug. They also have Bosch and Denso plugs for only about $70-75. And some others in between.

All things being equal, I'd rather spend $150 for a set and not $250. But I also don't want to screw around with the quality / performance.

So, I am wondering if anyone can comment on the reliability and performance of the various brands. Anything known to be crappy? Any go-to, no brainer choice?

Thanks

Nothing wrong with Denso as they're pretty much a NGK/NTK equivalent. I wouldn't consider any other brands when it comes to replacing the plugs and O2, A/F sensors.

Went with the Denso A/F sensors. Man the passenger side was a pita to get out.

For the reference of future searches, replacing both front A/F sensors fixed the Mode $06 test failures I was getting. Specifically -

TID:$01 CID:$01
- Rich to Lean sensor threshold voltage(constant)
Min: 30
Test result value: 14
FAIL


TID:$03 CID:$02
- Low sensor Voltage for switch time calculation
Min: 30
Test result value: 16
FAIL

I also reset the long and short term fuel trim records afterwards.

I am not sure if any of that work will do the truck any good but it makes me feel better.
