Cheaper O2 sensor source?

Anybody know a cheap/good source for 02 sensors? BMA wants $114 a piece for them, BAV auto wants about the same but with $16 shipping for standard delivery. That's about $250 for 2 stinkin sensors. Thanks

check that thread out scott. I remembered reading it a while back about substituting a ford o2 sensor for ours; they are supposedly identical but w/ a diff plug. i skimmed thru the thread and bruno stated that you could soldier the old plug to the new sensor and voila, new sensor for about $39/ea and some elbow grease

Thanks Phil. I wonder if those work on the v-8? Even if I used the NGK direct fit ones I would still save about $40 .

Phil, I know that the 540's show two different p/n's for a before and after cat O2 sensor (13532, a 2-wire and 13533, a 4-wire sensor). Anyone know if the aft sensor is actually a temp sensor or is it really an O2 sensor? Listings at http://www.oxygensensorwholesale.com/bmw_1995_540i.html imply I need two of each the front and back sensors... = 4???

I'll check the ETK tonight but I dont want to be shelling out ~$400US for sensors I don't need/have.

p.s. NGK's site says I only need 2 x p/n 25045.....headache...coming...ouch...

Cheers,
Duey

I know, I am very very helpful. Bueller?

I'm almost 100% positive that the 540's & 530's (M60) have two of the same O2 sensors..

I wonder what thats all about? Does look mighty unremoveable to me!

I've been looking into this too. Here's a NGK's universal sensor:

for $44.85 each:

So what's the difference between the NGk universal and the
NGK OE identical O2 sensor 25045 FC From 3/94 $94.85

besides $50 each?
