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

Harder and heavier than a dog toy should be, but it is sturdy.
Color: Mixed Blue
The outer rim is a very hard plastic, hard enough to dent and ding furniture. Too hard to throw in the house. Dog likes it but has difficulty getting his mouth around the sides as the item is very heavy for its size. Squeaker in the middle was a a nice surprise. Would not buy again.

Durable and well made.
Color: Mixed Blue
Our dog will chew any toy up in 2.5 seconds. This has lasted for quite some time. It's super hard which can be a downfall because they lose interest. Squeeker is hard to push down but overall it's outlasted other toys.

Dog toy
Color: Mixed Blue
Glad I bought this. My dog job is to destroy her toys or she thinks so. This is great for her chewing and catching while it will be sometime before she destroys this one
