Where can I get the bung that welds to the muffler for the air fuel ?
How many do I need and what is the preferred location.?

TIA

You can get them from Ebay or pretty much anywhere, its just an O2 sensor bung.

You should only need one for total AFR, but it depends on what exactly your doing and how accurate you want it. If you have carbs and you want it really accurate then one per side would be more than you need.


In reality one is fine and anywhere in line SHOULD work. If you have a collector I would put it about 6" after the collector.

Jegs or Summit should have the weld on bungs.
Is this for your 6 or 4 cyl engine?

vibrant, or even LUL Frozen Boost.

Thanks Andrew

Like - yes it is for the six

I get mine at a local speed shop. Do they have those in nyc?

I have recently found them on ebay shipped for around $6.

Carquest...almost any FLAPS

Actually you can use a nut with a 18 mm X 1.5 thread pitch.

Thanks all found them at my local flaps . $4.00 for a pair .

Oh, so you finally "got a pair"?

Sorry, couldnt resist

Locate that bung between 10 & 2 O'clock. Es muy importante. Did you buy a steel or SS bung?

I installed 2, I want to be able to monitor both carbs .

Is there a dual kit out there ot do I have to purchase 2 kits?

Can someone point me out to a good one .
Thanks

There ain't much difference in any of them other than the material. If you have SS exhaust you might want to order SS bungs. No, you need to order 2 individual bungs AFAIK. Ebay, Summitt and all the usual suspects

Thanks
