What it is, if you read the posts, are two spark plug anti foulers stacked (well that first link is just one) and then one is drilled out.

What it does is that it moves the chemical sensor far enough out of the main flow of exhaust to try to trick it into thinking everything is alright.

thats pretty much it.

You can buy these at Auto zone for four dollars. As described above, it helps eliminate the CEL for poor cat performance. You can also go to o2simulator.com and get a circuit that will simulate the o2 and tell the ECM that the CAT is running fine. I have a problem on my Maxima and both helped the problem. I haven't heard of many folks using them on a CTS unless you plan to bypass your cat.
