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.

Comfortable, relaxed fit semi-dress suit that fits true to size. Don't round up or down in size.
This suit fits true to size. We got the 9-10 size in white/tan for our above average height 7 year old, and the suit was just a little big (te Amazon algorithm recommended 9-10 based on past purchases and timing. He is the large side of his 2nd grade class, despite being one of the youngest, so I would say this suit would start fitting an average 8.5-9 year old boy. The fabric is a relaxed summer fabric, so good for semi-dress relaxed events. Our tan suit (and from the weathered gray/blue/green images, I assume all of the suits) seems like a casual menswear commercial shoot. The fabric isn't scratchy and our son said it is comfortable. It includes the picket flower, but I didn't think much of that plastic bloom.

Really cute suit for my son. Worth the price.
Color: Grey, Size: 10-11 Years, Color: Grey, Size: 10-11 Years
My son says he likes the color. He is 10 and we ordered the size 10 to 11 however he’s on the smaller side for 10 and he definitely has some room to grow so it will last us a while and it looks a little baggy on them for right now. However, the fabric is good quality. We like that it comes with a pocket square built-in and also the boutonniere for fancy occasions. I think this would be great for a wedding party or other occasions where you’d need more inexpensive but matching suits. Fabric quality reflects the price. The material is ok, but not gonna be an heirloom that’s passed down or anything. In the picture, he had shoved it into his clothes drawers and so it’s all wrinkled, but it actually does look great when it isn’t wrinkly. He’s been wearing this every week to Church on Sunday.
