I pulled one of mine on the 04 to put a spark plug anti-fouler in, to fix the P0420 code. Can't swear to it but I'm fairly sure it was a Denso.
Thank ! Did you replace the top one ( engine bay ) if so, how difficult was it ?
If you're looking to put in a defouler like Mark did, you would do it on the downstream sensor.
The one in the manifold isn't too difficult to reach. You can probably get it from either in the engine bay or from under the car if it's up on ramps.
