I just got an email from Rock Auto that had a list of wholesaler closeout parts for the xj6-xjr models. Besides drive belts and other parts I noticed they had Walker O2 sensors on sale for $47.89. I understand the originals were made by NTK and Rock sells those for $58.79. Just thought I would pass on the info.

 

I would have never have seen this I ordered a 4 for my xk8 thank you so much I never would have seen this. I saved a couple hundred dollars. Thank you.
