Plug n play, just remember to put some di-electric grease on the connection and make sure the cable is away from any moving part, like the drive shaft and make sure it will not rest on the exhaust pipe.

thank you! No clue why my local LR repair place wanted to charge me 700 dollars to do this!

I replaced all 4 of mine for 140.00. I happen to find brand new set on Ebay from guy who sold his D2 before installing them. Be sure and get the OEM, not aftermarket. Amazon usually has them the cheapest.

Nothing is showing up, so I don't know what you are asking about.
All mine came out with ease using a 7/8" wrench.

Easier to swap out O2 sensors than my first ever oil change. Buy the sensors from a reputable reseller/ebay and knock it out yourself. No more difficult than a tune-up, and a lot easier, too!

Also, I can't recall if the 99 is GEMS or Bosch? I know if it is Bosch, you want to get Bosch sensors, and the GEMS use NGK(not exactly sure) you might check on this.

Both GEMS and Bosch. NAS D1 was discontinued basically June of 99, NAS DII came about in July of 99 and both series had SD models.......
