An internal combustion engine uses oxygen just as fires require oxygen to keep aflame. There is no internal oxygen tank in a car for this purpose, as that wouldn’t be very efficient. Instead, Scion vehicle manufacturers equip cars with intakes that bring air inside to the Scion engine directly. Scion Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Scion car all the way to the engine, though stock versions aren’t always the most effective.
For that reason, many car owners turn to aftermarket Scion air intakes to increase the effectiveness and efficiency of their vehicles’ intake capacity. The greater the amount of oxygen supplied to the engine, the more power it can produce. Scion Cold air has more oxygen, for instance, so Scion cold air intakes have become popular Scion intake upgrades. Other upgrade types focus more on greater Scion air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Scion air intake system in your car.
