ROTOMOLD PLASTIC

A special rotomold process is used to manufacture our premium polymer 3.0T intake airbox. This method leverages complex shapes and angles to maximize internal volume for air supply and smooth flow for a true performance design. This molding style also produces consistent wall thickness, strong corners, and superior heat resistance for a cost-friendly intake without compromises.

 

SINGLE-PIECE AIRBOX
The entire intake is designed as a single-piece airbox to offer a seamless and complete look with an above factory quality fit and finish.
 

INTEGRATED VELOCITY STACK
Our motorsport-designed velocity stack creates a smooth transition from the large filter area to the turbo inlet with excellent laminar properties. This uniquely engineered detail produces a high inertia flow with reduced drag and power-robbing turbulence.
 

OPTIONAL CAST TURBO INLET
Adding the optional cast turbo inlet upgrade further reduces significant air restrictions while maintaining the largest size possible from the airbox to the turbocharger. The intake and turbo inlet combination further increases airflow from 37% (intake only) up to a combined 61% over stock!

 

Turbo inlet pipe is an optional upgrade and sold separately 

 

HYBRID TURBO READY
The intake and turbo inlet designs offer a straightforward and bolt-in job of available hybrid turbo upgrades. Our turbo-specific CNC-machined and o ring sealed adapters always maintain the largest size possible without introducing flow restrictions. Upgrading to a TTE or Pure Turbo hybrid is easy, simple, and hassle-free.

Hybrid turbo adapter rings are sold separately from the turbo inlet upgrade.

MULTI-PRESSURE ZONES
IE's multi-zone intake design delivers all the performance benefits of an open-filter intake while maintaining protection from hot engine bay air from under the hood. A constant ram air supply is forced in from the grille inlet, while any additional air demands are supplied from the low-pressure zone through the filter plate louvers. This dual-zone approach ensures airflow demands for any power level, even the most extreme builds.

AWESOME SOUND
The byproduct of a true performance-designed intake is more than power. Our uniquely engineered velocity stack, pressure zones, and extensive internal volume work together to release a myriad of turbo spools, engine throttle, and diverter blow-off sounds that transform your S4 or S5 with the under-hood acoustics of a genuine sports car.

PERFORMANCE RESULTS
Every inch of this intake system design has evolved from countless revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification to maximize performance benefits. The result is power gains of up to 19WHP and 21ft-lbs of torque, with even higher gains possible on hybrid turbo setups!  

FLOW RESULTS
Our polymer intake provides consistent gains of up to 61.43% CFM over stock during back-to-back flow bench testing! This increase in CFM proves the upgraded intake system's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades. 

EASY INSTALL
Install your new air intake using basic hand tools in no time. Our thermoplastic intake utilizes factory-style mounts that ensure a perfect and hassle-free fit.

Install time: 20 - 45 minutes

Good value for the money would buy again
Size: Vacuum Sealer + 30 Bags
This works great for some of the smaller items, especially whole fruits and vegetables, cheeses, meats etc. Like other vacuum sealers, anything wet is going to present a challenge. Overall very happy with this especially the convenience. Battery life on charge seems to last a relatively decent time. At first I thought it would quit working because I couldn't get any draw, however, realized that the cap had turned and needed to be repositioned. Almost acted like a off switch! But working fine chopped that one up to user error haha. As far as the reusable bags, pretty satisfied with that as well.

Great little sealer!
Size: Vacuum Sealer + 30 Bags
The vacuum sealer is wonderful, takes up very little space in the drawer and does an awesome job. We looked at some videos before we decided which one we wanted to buy. The best tip is when you are using the sealer try to have that area flat with no food under the sealer area. Love it that the bags are reuseable!

Good alternative to a full size vacuum sealer
Size: Vacuum Sealer + 30 Bags
This vacuum sealer is great. I had been reluctant to invest in a full size vacuum sealer so this was a great alternative, I’m totally sold on the versatility and ease of use. The included bags are a little tricky to close at first but they get easier to use as time goes on. The suction is sufficient for what I need (mostly storing meat bought in bulk in smaller portions in the freezer) and the bags definitely keep things fresh while preventing freezer burn. Despite the low price point the durability sees good so far with over a month of near daily use.

Great Sealer for the Price!
Size: Vacuum Sealer + 30 Bags
LOVE this portable sealer...and I own a bigger Vacuseal that I purchased from Costco. When you need a "quick and easy" sealer for foods, this works and is easy to use. It doesn't require space and I like the simple look. The bags are reusable (need to wash them) and are good quality. Just make sure that you "zip" the seal completely. Great sealer for the price!
