Do I run it under the car and up?
Do I run it through the cornering light on the same side as the airbox?
Or do I run it through a scoop in the hood?
I would think that the closer to the intake, the better. Right?
By the way, my car is a 1990 Nissan Stanza.
Going from bigger tubing to smaller tubing(to fit it on the intake) is better right?
If I eliminate the factory air box and simply run it into the car, into the k&n, into another pipe and into the intake, is it fine?

So many questions!!!!
