THE QUALITY POLYMER INTAKE
This cold air intake is manufactured from a high-quality rotomold procedure that produces a superior plastic material with consistent wall thickness, strong corners, and excellent heat resistance. Enjoy a proper motorsport-designed intake system without compromise.
PERFORMANCE FIRST
The internal volume of the intake and its complex shapes are the results of application-specific engineering for the Audi B9 platform. Every inch has been performance designed to feed your turbocharger with the most airflow possible.
THROTTLE DOWN, SOUND ON
The stock airbox on your Audi A4 or A5 2.0T has been manufactured to silence all engine and turbo sounds at any performance cost. Upgrading your air system with an IE polymer intake will release a symphony of engine throttle, spool, and blow-off sounds that will be music to your ears.
MULTIPLE PRESSURE ZONES
This intake features high and low pressure zones to feed the turbocharger and engine demands for any power goal. The majority of fresh air supply is supplied to the filter from the grill. If additional air demands are required, the intake will pull low-pressure air through the filter cover as needed.
BUILT-IN VELOCITY STACK
The integrated velocity stack smooths the airflow from the large filter into the charge system with excellent laminar properties. This powerful design detail results in a very high inertia flow with reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger.
PRECISION DESIGN
3D scanning tools are leveraged to create a high-resolution digital environment allowing our engineers to take advantage of all available space for a complete performance design while ensuring a hassle-free install.

POWER RESULTS
Countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification has resulted in a performance intake design with power gains of up to 10-20HP on tuned engines!
FLOW BENCH TESTING
Back-to-back flow bench testing details consistent airflow gains of up to +70 CFM over stock! This increase shows efficiency over the factory parts and capability to provide increased airflow demands from ECU tunes and performance hardware upgrades.

The above gains are a result of various design details:
- The 5" air filter surface area and increased air volume improve turbo efficiency.
- The internal velocity stack provides a low-turbulence transition from the filter to the inlet.
- High & low-pressure zones channel low-temp airflow quickly to the engine while protecting it from radiant engine heat.

EXCELLENT choice for the money!!!
Color: White, Number of Items: 1
I have never written a chair review, however; I feel this product warrants it.
I got this chair to replace an old chair in my studio. I scoured Amazon for hours to find it, and I am glad that I took the time to do so!
I was worried about material quality and durability at this price point, but my expectations were FAR exceeded. The piece goes together with a quickness (for me, under 10 minutes), and I only glanced at the instructions once.
Suffice to say, setup is simple and intuitive. Once the chair is together, there is a slight amount of play where the base plate attaches to the shaft, however it isn't a ridiculous amount. I only noticed as I was examining it and being critical after my initial excitement.
The materials used are very good, and much better than you would likely get from other chairs at this price. The chrome finish is nice, and the chair PU is uniform color with no defects.
One really nice feature are the zippered arm rest covers; when they get dirty, which (being white) they eventually will, you can unzip them, lay them flat, and clean them laid out, as opposed to struggling to scrub around 90 degree angles. I am sure this was easier for the manufacturer, but the end result helps the end user as well. Good on them for that.
Another thing I am very happy with is the height; I am 6'4" in bare feet, and my wife is 5'0". We both fit comfortably after adjusting. They definitely got the seat height right. And to that point (of size), at my height, and 260 pounds, there is plenty of room at the sides. Mind you, however, I am fit. That is not to say that a 5'10" guy that is 260 will find it comfortable. He may not. That said, most people should fit in this without an issue.
The casters had a positive snapping-in, and roll over my low carpet easily. This chair is definitely well built, save for the slight play mentioned earlier. In no way does that detract from it at all. The aesthetic fits my studio perfectly, and in all, I would not hesitate to recommend this chair.
If I have any issues with it, I will post an update review, but so far so good. I really love it. If you like the way it looks, pull the trigger. It is definitely worth the price, and more.

A great choice at affordable price
Color: White, Number of Items: 1, Color: White, Number of Items: 1
The design of the chair is sleek and nice looking at a very affordable price and a decent quality. It is the cheaper version of a more expensive one. The wheels move easily; the back of the chair tilts just enough; it is a deep chair to support my back (only 5"3), so I added a back pillow making perfectly comfortable to provide support needed for long period of times. If I have a negative comment, it is about the back of the chair being black so purely matter of esthetic.: and armrests narrower than I'd like and wrapped with 2 pieces of leather connected with a piece of fabric a bit loose with a zipper which will allow overtime to be completely removed and left with chrome completely if wearing out or simply if you prefer that look so options. A great purchase

Great looking chair, a bit hard, fantastic value!
Color: White, Number of Items: 1, Color: White, Number of Items: 1
3 for comfort, 5+ for looks and 5 for ease of putting together so I landed on a 4+. I absolutely love the way this chair looks and it accents my other darker office items well. I'm 5'4" and can sit in the chair, all the way back without a pillow so the size works well for me. The back support is fine and you can adjust it if you want it straighter or rock back & forth. I changed out the casters for a more rollerblade type wheel when so I can't speak to the rollability of the included casters, but works well with the wheels I installed. Fantastic value and I'm soo glad I purchased it!

Unbelievable!!!
Color: White, Number of Items: 1, Color: White, Number of Items: 1
First off, let me say wow! When I received this, I didn’t expect much because of the price, but I am blown away with the care that was given in the packaging alone, the simplicity of putting it together with the detailed yet brief instruction page, and the ability to put this together with one person. Took me less than 40mins. Highly recommend!!! And in fact, I’m purchasing another one right now as I’m sitting here rocking in my new beautiful chair.
UPDATE: a lot of negative reviews are basically user error. To attach the wheels, to snap on, I used a rubber (not metal) mallet to tap them in. To the leveling review, you have one arm on backwards. To the screw passing through, you may be correct but double check you didn’t use the required screws elsewhere. And the person saying it doesn’t recline, you have to release the lock - pull the up and down lever out and away from the seat. Good luck all!
Bought a second one - same thoughts as above. Pretty awesome chair.
