ngk

You mean NTK right? NGK makes plugs and NTK makes oxygen sensors correct?

I've had good luck with denso.

Yes.

This is hearsay as I haven't had any issues with mine, but from I've heard, bosch is a hit and miss, so I'd go with an NTK or Denso, etc. instead. Only reason I went with bosch is I got it at cost + they had a rebate, so couldn't pass it up (needed an O2); it seems to work fine, but just a heads up about the word on the internet about that brand.

In 503 I run a Bosch. In 1051, I run a Bosch narrowband and a Bosch wideband via PLX. All three work great. I was using the WB in 1051 simulated as a narrowband as well, but went back to a real narrowband as I feel they're better during closed loop operation.

^^^That's good to know about bosch; it's so hard to go off what people say on the internet anymore, but just had heard it more than a few times and not just their O2 sensors (as far as being hit and miss), but who knows. As long as mine keeps working, not going to go out of my way to change it over. (although do need to get me a wideband for tuning; have the bung, but it's plugged off for now).

Where the bosch units seem to fall short is in obd2 cars with self circuit tests. the resistance values are sometimes off & lead to coding. this is if no concern to us. so yup bosh will also work just fine.

I do recommend staying away from any of the universal wire-em to your plug types though.
