o2 sensors
The new DENSO O2 sensor for c5 should do the trick. These new o2 you can run fuel additive or race gas without any issue for me anyway. Everytime i ran race gas with stock o2 or bosch sensor the code were my biggest issue. After 6 months with DENSO no problem at all. I hope this help you guys.

http://www.sparkplugs.com has Denso OE identical sensors.
Just fill in the car information and then go to 02 sensors on the pull down menu right under the car description near the top of the page.

My front right o2 sensor threw a code recently, but it has settled down for the moment. I may need some new ones soon. It is hardly stock; I think that the o2 sensor may be the only stock part of my exhaust!

Denso OE Fit O2's
I just replaced my stockers at the recommendation of LAPD's tuner, and the Denso's work great 
My C5 feels like it got a tune-up, and runs smoother at WOT 
I puchased them from sparkplugs.com.......

OEM Denso's
I purchased the OEM replacements #234-4012 $43.98 ea. They have the correct harness connector and plug right in. I pulled 398rwhp with one O2 sensor on it's way out, and now my 01 Vette runs awesome with the new Denso's
