What companies make good o2 sensors?
 

just curious as to what manufacturers other than oem have o2 sensors both primary and secondary that work well with g3 integras odb2. I think ngk does but what else is out there and other than oem whats best?

NGK or Denso

denso ftw.

NGK/NTK sensors.......

same as OEM sensor but like half the cost.

check out http://clubplug.net/canada/ for ngk sensors at good prices.....you just need to find the part number yourself and locate it on the site.

That's where I bought mine from OBD1 FTW no need for a second one. Beside if your getting tuned, your gonna have to convert to OBD1 anyways.

I have a question, how do you know if your O2 Sensor is faulty or not working properly?

the part number for clubplug.net for our cars is 24172, i ordered one yesturday.

yeah.... im not planning on tuning the car. In fact if possible i may just hollow out my old car sound cat and bolt that up til the end of summer then slap on a new cat before my etest. Im going to have my buddies mechanic hook up an odb2 advanced scanner tool, hopefully that will shed some light on why my cat for the second time in two years has burnt out. I'm sure i'll at least need the secondary o2 replaced for my engine light that i've had for code 67. Even after resetting the ecu with the last cat it came on so im guessing its shot too.

The NGK 24172 O2 Sensor also fits OBD2 cats. I did a lot of research before purchasing. Its a direct replacement fit.

if you're burning out cats, i think that means you're running rich
