O2 Sencor question

[blastedM3]

My car is not passing emissions and i have done all the things to tune it up besides an O2 sencor.

I went to the dealer to get one and the price i got was $350...i said hell no and i walked out.

Anyone know a place i can get one cheaper or if someone on here has one i would be glad to buy it off u.

Its for a 91 318 ic.

Any help is appreciated

What you do if ur good with electronics is buy a o2 sensor for a 89 e30 325i which should be like 60 - 80 bucks. then you take out your old o2 sensor and cut off the old sensor leaving the wiring and you solder on the new one. You cant just put the 325 one in because the plug is different and the wires are way too short. I can give you a hand if you need.
