Box intakes can make more power than regular intakes, and they are easier to make; however, the horsepower comes at higher rpm's with a significant sacrifice in torque.

Most of the street oriented cars out there need intakes with longer runners in order to keep the velocity up through the intake path. This gives you that nice seat of the pants power. When you use a box intake, the only way to keep the velocity and volume of the air up is to increase the rpms...probably higher than you would want to go on a N/A street engine.

Of course, if you're running a blower or turbo, they work pretty good...the blower takes care of all the air-speed issues.

For the street, I wouldn't run a box intake on a N/A 302.
