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, Cadillac STS vehicle manufacturers equip cars with intakes that bring air inside to the Cadillac STS engine directly. Cadillac STS Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the Cadillac STS 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 Cadillac STS 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. Cadillac STS Cold air has more oxygen, for instance, so Cadillac STS cold air intakes have become popular Cadillac STS intake upgrades. Other upgrade types focus more on greater Cadillac STS air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Cadillac STS air intake system in your car.
This Neuspeed exhaust for my Jetta is incredible! Now my car sound so good and it is not too loud.
I didn't give them 5 star cuz the shipping time took a bit long. The quality is 5 star
