In the 3rd and last part of this series, I run the ducting for the air box, test fit it into the car, get it painted, and then install it in the car with a filter.
In part 2, I design and fabricate the secondary air box, which will allow air to be brought in from under the car. I use Adobe Illustrator to create the box pieces and then use a laser cutter to cut the shapes. Finally, I assemble the box and test fit it in the car.
I install a custom air box that I got from Japan into my 1985 Mazda RX-7. In part 1, I relocate the radiator coolant overflow reservoir in order to make room for the air box.
