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!!!!
