Based on my first purchase experience with Rockauto about 5 years ago I have never dealt with them again.
My experience with RockAuto.com

And Amazon generally gives free shipping on them. Even though they aren't at the moment, they are $47 and change.

 

Heat the exhaust with a blow torch, the O2 will break free more easily. And I think the front plugs are a PITA to get to. The best way to get to them without breaking anything is to remove the coil pack.

 

That's totally understandable. If I had similar experience, I'd send my money else where... or no where. I've gone over 5 years without *** cable tv, even though there isn't another choice here, because of their customer service.

Personally I've had good luck with Rockauto on parts for japanese cars, but they just don't seem to have much for a Disco 2. I bought a bunch of coolant hoses for the Disco 1, and they were about 10% of the price of Land Rover hoses, and probably worth about that..

 

Anyone know if these have the connectors on them already? hard to tell from description

Amazon.com: NGK 25044 Oxygen Sensor - NGK/NTK Packaging: Automotive

 

They should have the connector on them, at least the ones I got with the same part# did.

 

Well I guess I've been lucky with Rock Auto because they have never done me wrong but Amazon does have the same sensor for cheaper with free shipping.

 

I just ordered a pair of O2's for my truck today from Amazon, $99.41 with shipping.

 

got my 4 from amazon...know the back two will be a piece of cake...front driver side looks easy enough to reach plug...little worried about front passenger side because i can't even see the plug. also, how important is it to use the designated tool for removing and installing these or will regular wrenches do the job?

 

Well, I went ahead and overpaid for the special socket from rover parts. Looks like that goes down into the holes where the o2's are plus you can attach an extension with ratchet to reach those front ones easily.

 

How much was the socket? Did it work well?
