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, Audi A4 vehicle manufacturers equip cars with intakes that bring air inside to the Audi A4 engine directly. Audi A4 Air intakes are designed to provide the least inhibited route possible for the air to reach from outside the 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 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. Audi A4 Cold air has more oxygen, for instance, so Audi A4 cold air intakes have become popular Audi A4 intake upgrades. Other upgrade types focus more on greater Audi A4 air intake capacity period, but either way, you’ll end up with a better performing engine using an upgraded Audi A4 air intake system in your car.

I would have rated these a 5 if it were not for the fact that they needed some additional sealant around the lens. Luckily I had some left over rubber sealant lying around - I'd read about and experienced this before with my other aftermarket lights. Overall I am very satisfied with the product and the customer service. I was notified of a short backorder (about a week) shortly after placing my order, which happens from time to time. Wes kept me updated and called me as soon as the item left. Great guys to deal with!

This exhaust is amazing! my car runs more smooth now and sound is incredible at downshift.
There was a slight scratch in the clear coat that I had to buff out. All in all a nice piece. I dont think anyone else makes a carbon N54 engine cover. Item reached me in 2 days though, that was impressive.
The cayenne kit I got is absolutely high end quality product. The body shop said this is some good stuff! Thank you guys
