o2 sensor question

http://shop.carbodyparts.net/inventory-12862.html

is this the one you used the generic 4 wire for 91-97 318is?

let me know how that goes and if so can you take a picture or to Do you just cut the old wires and splice it on to the existing screw cap on the air box?

We soldered my wires together. It is a four wire but the plug does not go to the airbox. Its on a bracket about where the front battery tray is.

The catco direct fit was made wrong. I was able to use the O2 sensor but I'm going to have to send the cat back to the manufacturer.

Still haven't got it in yet but I took a picture of the Catco direct fit converter. Looks like a decent job to me.

progress?

This is the cheapest Ive found. http://shop.carbodyparts.net/search....991&part_type=

I just ordered the 4 wire for my car a couple days ago. It should be here tomorrow.

I was wondering if the o2 sensor on an m42 is a 3 or 4-wire? I am also looking at getting one at a reasonable price. Any response is appreciated and if you know where to get them shoot me a link.

thanks
