Plug Wires and O2 Sensors

Wanted to know if anyone has used Borg Warner plug wires on their 00-06 Tahoe. The BW wires are 8.5 mm while the AC Delco are 7.0mm. I am battling a p0430 code and I am going to replace all of the O2 sensors, plugs, wires and fuel filter and air filter this weekend. I'm using AC plugs (Iridium) and Bosch O2 sensors. Really wanted AC O2 sensors, but money is tight. Any advise would be appreciated. If anyone has had any good or bad exp. with Bosch O2 sensors let me know.
