I have for sale all 4 (pre & post cat) original BMW oxygen sensors, out of my 2003 540i.
The O2 sensors only have 69000 KM's on them and are in 100% perfect working condition.
They do not throw any codes/warning lights and have a usual life expectancy of at least 120000 KM's.
Replacing your worn oxygen sensors will lower your fuel consumption by +/- 10%, so these will pay for themselves in about 4 months time.
I'm selling these, because I'm about to do some Dinan mods and am anal about having all new sensors on my car.
Giving these away at a fraction of the cost.
Only $30/ea or $100/set of 4 !!!
Free GTA pickup/delivery or $10 for shipping
100% working order w/ 14 day money back guaranty !
