Quick one re lambda sensor

So this may sound stupid lol but want to double check that the one in the manifold is pre cat lambda ?
Sounds stupid but looking at all the different ones it threw me a bit as there are so many lol no idea why their are so many different ones with massive price differences on one site lol I know upstream is before the cat (in the manifold ) so presuming pre is the same

You would be correct, pre cat just means before the cat.. post cat would be downstream o2 sensor
price difference may be due to quality/brand and some older Hondas run single wire o2 sensors some run 4 wire, just make sure you get the right one..
