Denso 234-4011 Oxygen Sensor
This is a Denso 234-4011 O2 sensor that came out of a '99 Civic Si, but fits Integras and possibly other models. I purchased this for my new engine build, but removed it several months later after finding out that Hondata S300 doesn't need it, especially since I have a wideband. It's pretty close to being brand new. Asking $25. PM or post here if you're interested, thanks.
