Are there any differences between brands of oxygen sensors? Besides pricing. Im looking at replacing all 3 of mine. The brands i found are Walker, Denzo, and Bosch. Thanks in advance.

 

I'm sure there are some differences in how each company researches and developes their product. I can't tell you specifics but, I replace the two fronts with Denso and I am very happy with their product. Denso seems to lean closer towards the Asian market more than the other 2 you have mentioned. Basically they seem to have their sheet together.

 

nice...ill probably go with them. hines ward is 1/2 asian. so i guess that means they are good too

 

i just replaced my rear o2 with a universal 4 wire i got off ebay for $20. after crimping, i wrapped each wire individually then then all 4 with electrical tape for extra insulation. the orig OEM was a bosch. no probs, just reset the ecu manually. dealership prices are crazy. i would go for the best price...

 

I need to replace the first sensor in bank 1, which one is that?

 

almost 100% sure its the front one

 

Yea I was wonderin about this too... Only name that rang a bell was Bosch but id like to know if others are running walker and denso with no probs too

 

I'm running one bosch and one walker i got from oxygensensors.com with no problems so far. Cost about 75 for the bosch at the parts store and only 60 through the site. Hope that helps

 

1 is left bank in the front exhaust manifold, 2 is right side of engine . firewall side, 3 is rear, under the car near just after the cat. the front 2 are 3 wire, the biggest difference in replacements is if they are universal meaning you have to splice and crimp the wires and use the existing plug and play adaptor or the kind you just plug in with an new adaptor, as well, oem style. bosch, denso, walker are all good. the front 2 are the most important but as long as the wires are long enough, you can save a ton by going universal.

 

So the first sensor in bank 1 is the sensor I can see while looking down at the engine in the front, the sensor is to my left (towards the passenger side) and down a little ways?
