In Reply to: O2 Sensor tip replacement kits? posted by Chief on September 27, 2001 at 02:43:58:
You can buy the oxygen sensor for a little over $100 (Maximillian or Hendricks BMW) and the "pigtail" costs around $70. It is something you replace every 60K miles and directly influences the car's performance. In my opinion, don't skimp on the price. Buy the real thing.
Anyone have experience with these kits that suggest you unscrew the sensor tip from the housing, cut the wires, and replace/splice with their new tip? Are they as good as buying the entire assy. w/wiring?
