ROTOMOLD PLASTIC

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
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.

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.

MULTI-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.

AWESOME SOUND
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.

PERFORMANCE 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 RESULTS
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.

EASY INSTALL
Install your new air intake with basic hand tools in only minutes. Our polymer intake is a direct factory upgrade with stock-style mounts for a perfect, hassle-free installation.

Bang for your buck!
Size: 1 Pair, Color: Black
Bought these for my Dell computer because the built-in speakers were hard to hear. These made a big difference right away. Sound is much louder and clear for music, videos, and everyday use. They don’t have a lot of bass, but for the price I really can’t complain. Good speakers if you’re looking for a simple and affordable upgrade.

Best used with Laptop
Size: 1 Pair, Color: Black
These speakers are of better quality than they seem and will probably surprise most if used properly. When hooked up to a computer or laptop (via usb and aux), they work AMAZING. But when I tried to hook them up to my ps5, the quality went way down— the sound ceiling and especially base is almost non existent when plugged into a gaming system. I still use them for my ps5 but only because I live in an apartment—when I move, I’m upgrading. However, the quality for the price is so good that I bought another pair for my classroom. It’s more than enough sound to get the job done. Classic, Solid Amazon brand quality getting the job done.

Budget Friendly Stereo Speakers for Both New & Old Mac Users alike.
Size: 1 Pair, Color: Black, Size: 1 Pair, Color: Black
I purchased these for my Father’s MacBook Air and he absolutely loves everything about them. It’s Ease of Use, and it’s Functionality with macOS despite it not being advertised on here. As a Windows Migrant to Now Mac User from my personal experience they work flawlessly on a Mac. The audio is great for what it is, and it’s USB powered making it to where you can repurpose old USB Cell Phone chargers into, PC/Mac Speaker Power Adapters in order to power it up. Without sacrificing your USB ports on your machines. Only downsides are you can’t control the lights, and that the cables are a little weird and do take some getting used to. Yet either way I highly recommend purchasing these Stereo Speakers for MacBook users, iMac users, Mac Studio users and Mac Mini users alike, who are looking for an Audio Upgrade while being budget conscious and all without sacrificing your desk space simultaneously.

A Great Pair of Small PC Speakers
Size: 1 Pair, Color: Silver, Size: 1 Pair, Color: Silver
These are great little pc speakers. They hookup easily, give off great sound, have an in line cord volume control and look great on the computer desk. The only thing missing is an on/off switch so you have to detach the usb to turn off the power, if desired, when the PC is on. My usb port is on the front of my desk top so it's easy.
