Nitrous with a 4spd

If you never miss a gear, pass on the window switch.

Think about why you'd want the window switch and the potential mishaps that may occur. It won't guarantee anything using one, but may remove the extra HP from an NOS kit just in case. Having an engine full of n2o, bouncing off the limiter, is not a good thing.
