is this a wideband o2 sensor that i will need to tune my B16A civic?http://cgi.ebay.com/ebaymotors/ws/eB...tem=2449357887

 

If you don't know then it's probably not a good idea to tune your own car. Looks exactly like what you need though and I thought I read somewhere those techedge wideband o2's are pretty good for the price. I am not a tuner though so you might want to check into it before buying it.
