How to Make a Ram Air System
Ram air systems offer a way to increase efficiency and horsepower for any vehicle. Essentially, a ram air system reroutes your vehicle's existing air intake system so that it is positioned on the front of the engine compartment, situated with a scoop pointed outward to increase the amount and speed of air taken in by the engine. Prefabricated ram air systems can be costly and complicated; however, it is possible to build your own from a few simple, inexpensive materials.
