Hello,
I know these O2 threads are beat to death, but my 6 month old Densos are fouling up. I have a 2002 WS6. What is the part number for Bosch O2's that are long enough to go around my headers.
Thanks!

Bosch is crap IMO. What do you mean fouling? Are the voltages not switching?

Well, I had my car tuned shortly after installing these Denso O2s. While he was plugged up to my car he was concerned about the passenger side not switching as high as it should and to keep an eye on it. 6 months later here we are. Do you recommend AC Delco then?

If you order AC Delcos you're gonna get Densos inside an AC Delco box. I've got NTK 02 sensors (the long ones for Corvettes) and so far so good.

Do you have a part number on the NTK O2 sensors(the long ones for the corvette) and can I get them from any parts store?

I recommend Denso. Like said above, AC Delco will sell you a Denso sensor in their box. Have you hooked up your own scanner to watch the voltages fluctuate? As long as they are switching between .1 and .9 volts, and not hovering around .45 at operating temp, they're fine.

You have a defective Denso or you have more oil blow-by than you're aware of.

Densos are the best sensors ever made........even better than the AC Delco 02 sensors when GM was still making them.

Rockauto.com.......about $40.00 each

Dealership......same identical sensor in an AC Delco box......as much as $180.00 each.

Bosch is garbage on a lot of cars. Some do work though.
