Hey guys I've been looking around and trying to find a wideband O2 sensor for my 05 zx4. Kind of confusing because the wide bands that I come up with all say thay they replace a different part number. So I have rattled my brain searching and now I come to you guys. 05 Ford Focus zx4 2.0 5 speed. they all say replaces Bosch part number but all I see are part numbers beginning with a 17 and the Bosch OE oxygen sensors I find fit my engine are all beginning with a 15. Heeeellllppppp!!!!

I don't have a stand alone gauge right now. I can read/write A/F Commands on my OBDLINK software, planned on attempting that before ordering a gauge. A buddy of mine did say that he wouldn't trust it and I should get a gauge, so I've been looking. He didn't answer me about whether a controller was needed. But I figured for Budget purposes I wanted to just start off with my software. Is that not a good idea?? And do I need a controller?? I do allot of Amazon shopping mainly do to budget. Found a wideband O2 for $40 that comes up when I search for my car, however I know better to trust everything that comes up. Having trouble referencing, but I think I got that figured out. Sooooo, any advice short of super expensive parts at the moment are appreciated!? Hey Tom, that link is the same sensor I was looking at on Amazon. Are they gauge specific??

The Wideband air fuel gauge is one of the most important tools to add to your Focus for Tuning , if its wrong you will damage the engine , I would buy a AEM 30-4110 and use it

Right, I've been studying the process of fuel mapping, reminds me why I got out of computers!! Lol I'm for an inexpensive way just start off. Ok, so gauge is a must, according to 2 people, which is more most could say. But what about a controller Tom?? Would it truly be best to just get the whole damn kit??

Ok, thank you Tom. A series of unfortunate events has come to a head today so it will definitely be taking a back seat. Unfortunately it was going to be at least partially my way out. Getting back into racing that is.

The difference in the 15 and 17 number thing is likely due to looking up your sensor which is a narrow band one.
