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, 2012 Audi A4 vehicle manufacturers equip cars with intakes that bring air inside to the 2012 Audi A4 engine directly. 2012 Audi A4 Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the 2012 Audi A4 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 2012 Audi A4 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. 2012 Audi A4 Cold air has more oxygen, for instance, so 2012 Audi A4 cold air intakes have become popular 2012 Audi A4 intake upgrades. Other upgrade types focus more on greater 2012 Audi A4 air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded 2012 Audi A4 air intake system in your car.
Nice product, only took me about 20 minutes to put it on my car.
I didn't give them 5 star cuz the shipping time took a bit long. The quality is 5 star
Easy to install. Highly recommended
