Intake o2 sensor

[BlackFox]

I'll be doing a KA-T setup. Usually on a car there's an o2 sensor on the intake. when you put a turbo kit where do you put the o2 sensor, or do you still need it? does anyone know if there's a hole in the for the o2 sensor on the intake pipe leading into the turbo?

I'm mainly talking about the xs-engineering kit.

You mean air temperature sensor. The O2 sensor is usually bolted to the exhaust manifold, not the intake box or plenum.
