Big/Small block MerCruiser O2 sensors
If you have a big block or small block mercruiser engine that has oxygen sensors pt# 8M2003959 and they go bad. You will be paying around $125 each.
On the other hand. You can buy the exact same oxygen sensor from GM pt# 12640453 https://cimg0.ibsrv.net/gimg/www.off...6019b12544.jpg on eBay all day for $48. I found a dealer that sold them to me for $35 each. |
Great info, thanks.
Quick check, RockAuto and Amazon (not 3rd party) sell for $35-38 also. |
