There are two and they are both located on the exhaust header pipe. Refer to this diagram for exact location.

I wish US spec 328's only had 2! I'm not looking foreward to replacing all 4 at $100+ ea. when that time comes. I'm tempted to do the sparkplug antifouler mod to try and make them last longer.

I never replaced the 02's on my car, worst case scenario your mpg drops a bit. I never noticed anything when mine went bad, check engine light was a little annoying but, oh well.

well i can confirm that euro spec 328i's have 2 o2 sensors and us models 4. my dealership wanted £155.00 each (which is about $442.90 for both) but on ebay they were £50 each. so if anyone over there needs one (not sure how much they are on us ebay) have a look. it may be cheaper to buy one from here and ship it over.

actually, while i'm here question. on my tailpipe exit one side has a vertically pivoting butterfly valve. what's it for.? damn emissions regulations. didn't have this problem on my '79 trans am over here.heh heh

The butterfly valve, stays closed until a certain rpm, I think it's there for sound purposes (keep it quiet). It works via a vacuum hose. A lot of people stick a golf tee in the vacuum line so the valve will always be open.

^^^^^^+1 Sometimes referred to as the golf tee mod, just a little noisier.
I've done it myself.

hey guys!!!!

The valve is controlled by vacuum.. from memory it loses pressure about 2500rpm and starts opening. This creates less back pressure and more noise!!! So sounds sweet and creates more power.

Having a 320i.. i just opted for a triflow muffler.. sound all the time and another 20hp

The butterfly valve being open doesn't create more power. Well if .0001hp counts, then maybe.

20hp from a muffler isn't going to happen either.
