Sparkplugs.com has a sale on this part number it shows is for my vehicle.
Denso

234-1051 $26.99

I dont think my o2 sensor is bad, but for this price why not. I have to smog soon. Is this the correct part number?
I hear people buying the 1052 model, but it shows this one for mine.

 

I just checked, that`s the right one, and that`s a great price considering what they normally cost. If you can afford it, buy two.

 

RockAuto (www.RockAuto.com) calls that same part number for the Denso part, and they want 23.79. They also have a close-out part for $15.08.

In the grand scheme of things, any of those prices is low enough that it is very tempting to replace one "on spec."

 

Just purchased it.

Thanks for the heads up, guys. I'll be replacing the NTK unit on my '86 soon.
