AEM wideband

[sleepyEP3]

Hey guys, I've got an o2 sensor that went bad (primary) and I was wondering, does the aem wideband O2 take the place of your primary? If so I will just buy that, rather than spend the money for both. Or do you have to drill a second hole for it. I have no experience with these things whatsoever. Please help as I do not want to buy an o2 from whoever for around $200 when I could replace it with something better. Also, does anyone know if boosting will make you burn up O2 sensors faster than normal?

you have to drill a hole for the wideband gauge. the ECU adjusts fuel with your primiary o2 sensor so you will need that or your car will run like shit
