As the title says...I have an AEM EMS for a 99 to 00 Civic Si, or any other car that runs a B16A2 for that matter, for $1200. It still has the plastic covering on it and was never installed. Car died before I could get to using it.

I also have the UEGO wideband O2 with A/F Gaugue for sell with it as well for an extra $300. I do not have a pic of the gauge but can get one tomorrow. This is also the same story as the EMS above...never installed or used.

PM if interested.
