For the customer who demands quality and performance, IE's new Audi B9 S4/S5 Intake System delivers on power, sound, and quality wrapped up into a product that reflects the Audi S trim as a true performance machine. IE's engineers took a "no expense spared" approach to design the ultimate intake system solution that delivers on looks, fit, and most importantly - power!

PERFORMANCE

Back-to-back dyno testing shows consistent power gains across the entire RPM band with +16HP and +16TQ over the stock intake without any additional hardware upgrades.

Carbon Fiber

Carbon fiber construction was used to create complex shapes and angles that can not be achieved with sheet metal bends. This design style utilizes every millimeter available in the oddly shaped modern engine bay for a very large air supply and smooth delivery.

Sound

IE's intake system takes full advantage of a performance design including the turbocharger spool, engine throttle, and diverter valve sounds that come along with it. The unique velocity stack and bottom louver design create a tuned engine note that sounds classy, yet powerful at the same time.

Seamless

The full-carbon 1-piece design reduces the chances of air leaks from joints, finicky installs, rubbing noises, or parts working loose over time while also providing an easier install. Unlike competitor designs, this does not require any additional parts sold separately to complete the intake.

Easy Install

The install process is simple and can be done quickly with basic tools. The airbox utilizes factory-style mounts that ensure a perfect fit and allow for natural engine movement which keeps intake components from getting damaged. The typical install time is under 1 hour.

Velocity Stack

The bell mouth shape channels air flow from the large internal airbox into the turbocharger as quickly as possible. This velocity stack creates a very high inertia flow from the massive 5" filter with very low drag or power-robbing turbulence.  

High Flow 

Outside high-pressure flow from the front of the grille acts as a ram air design for the majority of the air supply. Additionally, the bottom plate louvers pull extra required air as needed from the low-pressure zone under the intake.

Flow Testing

Back-to-back flow bench results show constant and consistent CFM (cubic feet per minute) gains over stock at any test pressure (in/H20). This data means the engine is able to take advantage of larger airflow across the entire RPM band.

Precision Fit 

To ensure a perfect fit, 3D scanning tools are used to create a digital duplicate of the vehicle's engine bay, grille, bumper, and hood. This provides an incredibly high-resolution environment to engineer and prototype the intake design.

Quality Parts

No flimsy parts or quality sacrifices found here! Only the best materials and design features were used for a top-tier look, fit, function, and long-life reliability.

Suited me Well
Size: Small, Color: Black
This 2 Piece Slim Fit Suit Set is hands down the best suit for the price. I bought it for a formal Christmas work party, and it was such a cheap, easy, and quick way to get exactly what I needed — especially since I hate shopping. Honestly, you would never guess I paid as little as I did. It looks sharp, fits great, and feels much more expensive than it is. The color was a true black, which I really appreciated. It looked clean and classic — perfect for a formal event. It did arrive a bit wrinkled from the packaging, so I had to iron it initially. But it was very easy to iron, and once I did, it stayed pretty crisp throughout the night. It didn’t wrinkle much at all while wearing it. It’s also way better than going to a store and paying triple the price. And definitely better than renting — now I actually own it and can wear it again whenever I need it. The fit is perfect if you’re slim. I’m skinny as a rail, and the slim fit worked exactly how I hoped. The jacket isn’t too tight, not too long, and I can move my arms easily without feeling restricted. The whole suit is comfortable and easy to move around in — not stiff like some formalwear can be. It also has handy pockets for your phone and wallet. Overall, you can’t go wrong with this suit. Great price, true black color, comfortable fit, and sharp look. Highly recommend.

Amazing fit and quality for the price
Size: Medium, Color: Red
Gotta say I was 100% impressed w this suit! And for the price!!?? Nice fabric. Great fit. Great quality. Fit right out of the box! No alterations were even needed. My 14 year old son is 6'2 and around 155lbs. Broad shoulders. Slender build. We ordered the medium and it fit just right. You really cant go wrong w this suit even if you need to get some alterations you cannot beat the price.

Quick Delivery & Surprisingly Good Quality
Size: Large, Color: Light Gray, Size: Large, Color: Light Gray
I needed a suit on short notice and didn’t want to spend a fortune, so I took a chance on this gray suit—and I’m really glad I did. For the price, I wasn’t expecting much, but the quality is honestly impressive. The fabric feels solid and looks sharp, not cheap or shiny like other budget suits I’ve seen. Shipping was fast—I received it in just a couple of days, which was perfect for my tight timeline. The fit was nearly spot-on right out of the box. The jacket and pants fit well overall, though the sleeves were a bit long for my arms. If you need a reliable suit fast without spending a lot, this is a solid option. It exceeded my expectations for the cost and turnaround time.

men slim fit suit
Size: Small, Color: Red
I bought this suit for an 11 year old child for their sneaker ball at school. i order him a size small in men's (he wears a 32 in men pants) this suit fitted him well. the quality of the suit had actually exceeded my expectation. this suit was worth the money and the material. I would definitely order this suit for a young boy for a dance and you don't have to worry about spending a substantial amount of money. the material for the suit was good quality and I washed it in the washer machine.

True to size
Size: X-Small, Color: Black
This suit fits true to size and does not look cheap. I was in a hurry to find something and couldn’t be happier with what we received. My husband looked extremely handsome!
