Default wideband bung install

Hey now!

So I've got this LC1 WB kit, and now that the begi has arrived I can tack this bung into place on the pipe.

The question, this sucker (bung) is like 2in long, how much of it needs to be inside the DP and how much needs to be on the outside? I'll try and get some pics up shortly incase no one knows what the hell I'm talking about.

Much thanks!

The bung fits flush on the pipe. The way I did it is drill a hole on the exhaust then set the nut over is with the wideband sensor in there and tack it. Pull out sensor and weld. Id also advise you to place the sensor between the 9 and 3 ocklock above horizontal.

Thanks, so the entire bung will be inside the pipe with the end of it flush with the outside?

I think with the bung flush I can get it at 12oclock but i'm not sure if the o2 loom will rub on the underbody or not. I may end up drilling it at 11 or 1.

Make sure the sensor is exposed in the exhaust stream. If it's tucked inside the bung, it may read incorrectly.

Yeah, with the o2 screwed all the way into the bung, the o2 only sticks out maybe a 1/4in from the bung opening. Do you have to do some fabing of the bung or is it a direct fit item?

You may have to trim it. Mine came with the LC-1 and was only .750" long. so the sensor hung out of it.

Take the O2 sensor into a hardware store and buy the nut it threads into the easiest. I forget what size it takes.

That bung is junk.

for future reference, this is a real bung http://www.summitracing.com/parts/AVM-35-4005

Notice the lip on it? It makes life much easier.

Google: O2 sensor thread tap, it may tell you the size.
