MY 2nd o2 sensor got stuck in my aftermarket cat and would not come out & i sold it with the rest of my spoon exhaust.

I need a new one but not sure what best factory replacement would be that has the factory connector as well. Most of them i have scene are splice set ups & I dont want to pay 300 the dealer wants for a new one.

Also is it gona be a A/F problem if I drive my ITR with a open header just cruising on the freeway to my local exhaust shop. I didnt know that the SMSP set up was not bolt up and needed to be welded up. I have the JDM final drive and rpms on freeway would be 3900-4000K

Thanks for any feedback

Look up the denso part number for your car at http://www.sparkplugs.com then search for that part number on amazon.com to see if it's cheaper.

If you throw a code getting to the shop just pull the ecu fuse for > 30? seconds after its done. The ecu will relearn the STFT and LTFT with the new exhaust.

 

Thanks for the link

The 02 sensor in the cat is that the upstream or downstream one? I assume its the down stream but just want to make sure

Before is upstream. After is downstream.

 

Bosh. thats what ive used and they are great.

 

You can get the correct denso replacement from autozone .com. Come with a few year warranty also

 

I've got a used OEM one FS... you have PM.

 

I'v used NGK PN 24172 many time throughout my vehicles:

NTK and Denso, either is a great choice

amazon usually carries both and or rock auto. the upstream is cheap, normally $40 or so

 

You can get the exact oem replacement denso one from rockauto.com for cheap I paid $30 shipped for mine I think it was the upstream if I remember right. I know the dude in parts at Acura and took it to him to give him a hard time he asked where I got it cause its the exact same as he had and he wanted to buy one at the price I got it lol

 

Do not go bosch or anything other than denso with OEM direct fit, have replaced three lesser brand sensors amongst friends cars.
