Best O2 sensor on the market?

[CGASTON]

Can someone tell me what is the best O2 sensor for 87 GN? Where can I get them?

[CGASTON]

These are stock O2s?

 

[gn4u2c]

yes sir

 

[CGASTON]

That is awesome. But what if your running performance? High horsepower motor?

 

[blackgn1]

Denso!

if your talking about stock O2 stay ac delco

now if your talking high horsepower you should be looking into a wide band O2

 

[CGASTON]

I thought that you must run a stock O2 with and wideband. Is that correct?

o2

Denso #234-1001

 

[Raymond Bunch]

Aforementioned x3 Denso is your best bet.

Performance means a wide range around here. If your basic bolt on's and a little extra boost (350whp or below) level stock is the best bet. Don't go throwing money at gadgets until you have a "FULL" understanding of how the stock works stock.
Now if your cranking it up 28-30psi, huge turbo, fuel management, squeezing every once yeah a wideband setup is a good move.
Myself along with many others have been very fast with just the stock 02 doing its thing. 10.50's on unopened motor here.. my next step is building a 4.5 so yeah that will have a wideband :biggrin:

what's the difference between the 234-1001 and the 234-1000 denso.

 

[dpasadena]

difference in part #'s

These sensors are the same but the only difference is that one has the correct connector for our cars and the other just has a bare wire and the old o2 connector must be spliced into the sensor.
