So I am having bit of trouble finding a guide to replace the sensors before and after the cat in my car. If anyone can point me in the direction of a guide or give me a basic explanation that would be great.
So far the quotes I have seem to around $900 for the two sensors plus labor. Has anyone used these sensors from sparesbox? Are they the two sensors that I need to replace? It almost seems to good to be true at that price compared to genuine.
Thanks.
