Installing a cold air intake is one of the first performance modifications a car enthusiast takes on. These systems are generally inexpensive and very simple to install. When compared to OEM, the aftermarket systems are designed with wider bore piping and minimal twists and bends, allowing the fresh cold air a straight shot to your intake manifold. Cooler air is more conducive to burning fuel due to its higher oxygen content. This allows for a more efficient fuel-burning process, resulting in increased power and improved fuel economy.
