Sup Homeys,

I have tried searching and I am finding conflicting information, even from the denso site.

I need to replace both of my oxygen sensors but don't know which 2 my car needs. On the denso site there's 4 o2 sensors listed for integras, it appears to be 2 for one model and 2 for another model, but it didn't specify which model, just days 1.8 trim for both, which doesn't help much. at least that's what I gathered from it.

What I want to know is which 2 sensor #s do I need?

They have it listed as 234-4011 &234-4209 for one, and 234-4209 &234-4659.

When I check eBay for denso oxygen sensors it gets worse, as these 234-4099 listed as well as other #s.

Does anyone know for sure which o2 sensors I need? I want to put this o2 sensor issue to bed already, it's been a problem ever since I bought this R but there were just too many other things that needed attention, like a complete tear down and rebuild of the motor, so the o2 sensors have been on the back burner for 3 years. It's time to get rid of the dam cel codes once and for all.

I was throwing the code for only the secondary o2 sensor, but I want to do both so I don't have to worry about the dam o2 sensors anymore.

Any help is most appreciated! Thanks Homeys!

What year is the car? If a 1998 according to Rock Auto you need a Denso 234-4011 for the up stream and 234-4659 for the downstream.

I have a 99 itr (Canadian) so I should be getting 234-4011&234-4659, assuming the sensors are the same from 98-01.

Oh and thank you very much also I forgot to say that originally!
