Default O2 Sensor

It seems my 02 sensor is flaky. Car likes to bog around 2500-3500RPM on cold engine or after driving, then letting it sit for 20-40 minutes and then starting to drive again.
Wideband O2 system would be quite nice, but I don't think i can afford that right now. I was thinking of ordering an NTK O2 sensor which goes for $33.74. NOPI claims it's an O.E. replacement. Is that good nuff? Any other recommendations, since I am already spending money on this?

Setup is: 90NA + (red paint) : + basic Greddy kit + Bipes.

I'd get the Bosche 4 wire sensor. It is probably about the same price as that NTK. I don't have the part number right here but someone will chime in with it soon...

If the NTK is a 1 wire sensor, I'd get the Bosch instead. I got one 2 weeks ago from Advanced Auto for $18.

What would the benefit of a 4 wire O2 sensor be?
Ben, did it come with a harness? If not how did you splice it in?

The 4 wire has a built in heater. The sensor doesn't work properly until it comes to temp, the heater makes it come to temp earlier.

The new sensor comes with a butt connector and some heat shrink. You'll need to get crimping pliers if you don't have any already. The bosch sensor and crimp tool will cost less than half of the plug in sensor, and you get to keep the crimp tool to use later. It's real handy.

Didn't do much shopping around, but Bosch part# 13275 is available at the AdvanceAutoParts for $51. Sounds a little steep. Is there a different part number that would work?

just go to autozone. They have what you need. It's something like $17.49 + tax.

sorry, I don't have the part #. It's the bosch 1 wire generic. Common item.
