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 XB vehicle manufacturers equip cars with intakes that bring air inside to the Scion XB engine directly. Scion XB Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Scion XB 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 XB 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 XB Cold air has more oxygen, for instance, so Scion XB cold air intakes have become popular Scion XB intake upgrades. Other upgrade types focus more on greater Scion XB air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Scion XB air intake system in your car.
