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.

Was a little worried about getting this exhaust because of the amazing price, but was really surprised. Shipping was fast. less than a week. Install was easy, bolted right up, everything where it's supposed to be. Looks really good on my car and sounds great. Nice deep sound, not buzzy. Loud but not TOO loud. Noticed the power increase immediately. Really good exhaust for those of us on a tight budget.

This is what I have been waiting for. good product with good price
This is my second set of spring for my GTR. I used to ride with Eibach but the front height is higher than my rear. Swift spring rides perfect. The height is even so my car dont look like a drag race car anymore. lol Anyways. I love this purchase

easy enough to install by myself in 20min. double side tape is not included so I had to get it from the store. Overall a good purchase. fast shipping
I bought my 94 civic cat back and it works good for me. I am not sure if my car is going faster now but it sounded darn good now.lol
