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