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

He was confused, I was amused!
Color: Turn Around, Size: Level 2
This toy was quite well made, the materials are solid and once assembled, its very sturdy! Super easy to put together too. It comes with two kinds of lids for the test tubes, three little holes (intermediate/ difficult) and one big hole (beginner/easy). So the actual toy was really nice. There was only one problem...for some inexplicable reason...my dog (3 yr/ 20lb/ shorkie) was afraid of it! He's used lots of puzzle / game toys in the past, but for some reason this one weirded him out. No matter what I did, I couldn't get him to even try moving the test tubes. The farthest I got was having him eat a treat off the edge of a test tube once or twice (hence the video, there's a piece of chicken sitting on the top). Mostly he would just growl at the toy or eye it suspiciously, and then run away. I would describe his overall attitude as agitated skepticism with a hint of annoyance...specifically toward me! (As if saying "what the heck is this thing??") I will say the customer service was pretty good. And I definitely got some personal entertainment watching my dog run around and growl at the toy that was just sitting there. (:

Can't beat the price if you have smaller dogs
Color: Turn Around, Size: Level 2
This is my 2nd one, which was bought for my mom's dogs. They absolutely love it when they come to my house. I live that they have to get their nose off the floor to figure it out and that there are more than 1 tube that they have to flip (think about). My only thumbs down isn't a big deal but would be the hard base. The treats fling off this base and can end up anywhere in the room. I think if it wasn't so hard, they wouldn't have to walk away from the activity or have to fight over who get the "reward" (It's usually the other dog waiting to chase where they fly off to). It doesn't flip over unless they run into it which doesn't happen often, although our dogs are all under 15 lbs. Imnsure if a bigger dog were to use this, it wouldn't stand up well and may break. It was easy to put together, and functions very well. Our dogs think this is the most fun toy out of all the interactive togs we have (which is A LOT).

Amazing!!!
Color: Turn Around, Size: Level 2
This is an amazing mental stimulation toy for my dog! And it’s a perfect one for dogs who are learning. He picked it up right away and loves it! I can’t wait to get the other ones they have. Seriously so amazing. My very active Aussie can spend 30 minutes doing this and not get bored.

Great for bored dogs
Color: Flip Board, Size: Level 2
Great dog puzzle! My pup loves this, he did chew the peg portion once he got them out so they can be put back in. They are tough for small dogs to get out so I think he plotted it out.

My dog is beside herself with glee
Color: Blue
This was a good find. My Lab has a soft mouth so she won’t destroy it, not sure how it would hold up for our neighbor’s German Shepherd with his strong jaws and big teeth.
