Denso o2 sensor ? Why are there two different O2 sensors for the front? Part # off the website I am looking at have the left as 234-4025 and the right as 234-4087. What is the difference? Thanks for any insight anyone can offer.
Yes, the sensors are all identical, wire lengths are just different.
Densos are the new AC Delco sensors. GM uses them now for their own sensors.
Don't know what "ls1lover" is talking about, Densos are easily the best sensors made right now. I'm running them. Its actually a better design then the original GM sensors. Better air flow into the sensor tips.
Don't be dumb an order AC Delcos from anyone, not even the dealership....you will get the AC Delco boxes but inside you will find Denso sensors. I had this happen at Bennet Auto. I also called my friend who is the parts manager at Sheehan Pontiac, he confirmed that they are using them now as GM's choice for 02 sensors. Just buy Densos for $40.00 from www.rockauto.com

Been running the Densos on my setup for the past 2 years.
Before the Densos, I ran the Bosch o2 sensors...they sucked! I was replacing them every year.
Since swapping to the Denso over 2 years, no problems at all!

Do you guys that use denso's have cammed cars? I burned through two set of the old style sensors in my car before I had it retuned and I need to replace with something that'll last a little bit.

And not only is my car cammed, its stroked 383, heads/cam, LT's, everything!
Putting down 500rwhp. The Densos i've been using for the past 2 years are working in my setup nicely.
