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.

Comfortable, Easy to Clean, and Held Up at Coachella
Size: 12, Color: White, Size: 12, Color: White
I’m really happy with this purchase. The shoes are very comfortable, and the product description is accurate. I followed the sizing recommendation based on my foot type and went one size up—they fit perfectly.
I bought these for Coachella, and they definitely held up. I was on my feet all day, and they stayed comfortable the entire time. What impressed me most is how easy they were to keep clean. At the end of each day, I was able to wipe them down and maintain their whiteness without much effort.
Once I got home, I gave them a deeper clean, and they honestly looked as good as new. Even the laces cleaned up easily.
Now I’ve transitioned them into my regular work shoes, and they still look great. Overall, I’m very satisfied with this purchase and would definitely recommend them.

Great shoes that are well made, lite weight, and comfortable.
Size: 12, Color: Brown
Just received my 2nd pair of shoes from Bruno Marc in a size 12. These are really lite and comfortable. It can be dressed down to be a casual shoe or dressed up with a nice suit. These run true to size so I ordered my usual size 12 and the fit was perfect. Being my 2nd pair of Bruno Marc's, I like the quality of their shoes and each shoe is described appropriately on fit and comfort. Insole of these shoes were awesome and provided soft comfort on the feet along with a slight arch support too. Will definitely consider ordering more Bruno Marc shoes in the future.

Cushioned, comfortable, stylish and a rubber sole!
Size: 10, Color: Brown
These shoes check multiple boxes for me, comfortable, cushioned, rubber sole and stylish. As my feet grow old and worn out, I'm on a constant search for comfortable, cushioned shoes that are suitable for work and dressier occasions. I have tried many expensive shoes that look great but either lack cushioning, arch support and or comfort. One of the nice things is these shoes have a rubber sole, where most cushioned shoes have the foam soles which are great, but they tend to lack grip particularly when its damp/wet. They have average arch support, but the insole is removable and I put my own cushioned arch support. Love these!

OG Style
I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.

Must buy: Comfort + Casual + Well Made / Ventilated
Size: 8, Color: Brown
Just buy it! I have put in roughly 15,000 steps in this shoes in 10 days and I can't believe how comfortable they are after this much rough use in short amount of time. I highly recommend this shoes to anyone looking for comfort in casual style.
