I paid about $60 from Amazon for O2's with plugs. Bosch.
There is absolutely no reason to give Altlantic British even more money with their inflated prices.

Atlantic British - too bad there is now some competition.
If you absolutely can't find the part, then use them and prepare to have your pockets emptied.

 

are these the ones?

I don't know about all Bosch sensors, but the Land Rover ones are made by NTK, OEM for Land Rover

 

Never use universal 02's with out plugs.

 

that was my thought also, I never had luck with anything universal.
Universal meens it will fit 8 out of 10, you can be sure that LR with be one of the other 2 that it doesnt fit.

 

How best to clean the female connector?
Any suggestions?
Thanks

 

Get CRC contact cleaner from the autoparts store.
Or, the CRC sensor cleaner used to clean a MAF.
