I have a prosport analog wideband af gauge kit for sell which I bought last month end. I have a receipt too. It's a brand new packing and have O2 sensors, instruction and everything. I haven't even opened most of the things and you can see that. It would have warranty too.
I am postponing installation of this gauge as I am going to work on suspension first and need some buk for that.
I am in Mountain View, CA. Leave me a message if interested.
here's the link I bought it from: Prosport Analog Wideband Kit - 52mm - Wideband Air/Fuel Gauges
I have attached couple pics. asking 200 or OBO ( I paid 229 + shipping )
