POLYMER AIRBOX

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.

SEAMLESS DESIGN

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.

BUILT-IN 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.

TURBO INLET UPGRADE

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 further increases airflow from 37% (intake only) up to a combined 61% over stock!

Turbo inlet pipe is an optional upgrade and can be purchased with your intake or added at a later date.

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.

HIGH-FLOW 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.

TURN UP THE FUN

The byproduct of a true performance-designed intake is more than power. Our uniquely engineered velocity stack, pressure zones, and extensive internal volume also 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.

PRECISION DESIGN

3D scanning tools are leveraged to create a high-resolution digital environment. This technology allows IE engineers to use all available space for a complete performance design while ensuring a hassle-free fit and installation.

Our cost-effective intake without compromising quality or performance.

EASY INSTALLATION

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

YOUR BUILD DESERVES THE BEST

Feed your 2.0T TSI GTI, Jetta, GLI, CC, or A3 with a supply of cold air with this direct-fit high-flow cold air intake kit. This intake features a generously-sized inlet pipe that connects to the OE mass air flow (MAF) sensor. The MAF sensor receives high-velocity air fed directly from a 5" bellmouth. Our high-flow bellmouth is neatly housed in a heat shield, which separates the air filter from the hot under-hood air, allowing only cold air to be drawn into the turbo inlet directly from the front of the car.

STOCK-LIKE DIRECT FIT

This air intake kit provides all the necessary piping and couplers to plumb the intake system from the turbo to the MAF and then to the heat shield. The heat shield installs using the OE grommets for easy maintenance and reliable mounting with no rubbing or interference with other factory parts.

HIGH-FLOW VELOCITY STACK

The air intake utilizes a high-flow bellmouth behind the air filter to deliver as much air as possible. This bellmouth design increases the air velocity to the MAF and pulls cold air equally from all directions into the filter. This bellmouth is securely fastened to the heat shield as a clean pass-through providing a solid mount for the air filter and turbo inlet pipe. You have no worry about the intake pipe moving around and causing damage unlike other intake kits on the market, which simply clamp the filter onto the end of the inlet pipe or MAF. Furthermore, the bellmouth opening allows for a filter with a very large surface area that can support any horsepower goal. The same filter and bellmouth design have been tested to support over 500HP!

THERMAL BLOCKING HEAT SHIELD

The IE heat shield is designed to create a thermal barrier blocking all of the radiant heat from the engine bay. Only cold air from the front of the vehicle is drawn into the filter from the opening in the radiator support keeping air intake temperatures as cold as possible. This allows factory placement of the intake to be used without placing the filter lower in the vehicle where it can be subjected to engine harming road debris or fluid.

DO YOU NEED AN SAI KIT?

The MK5/MK6 2.0T TSI engine has two different engine codes. CBFA engine codes are equipped from the factory with a secondary air injection (SAI) pump that connects to the factory intake box. These engines require a small breather filter for this SAI line when installing an aftermarket intake. CCTA engine codes do not have this SAI pump and will not require this filter. Identify your engine code using the photos below, and add an SAI filter kit above if needed when ordering your intake.

EASY INSTALLATION

Installation is quick and easy to install with basic tools. The process should take around an hour for most enthusiasts.

IS YOUR STOCK INLET ROBBING POWER?

The factory installed plastic turbo inlet found installed on your VW or Audi Gen 3 1.8T or 2.0T TSI engine is adequate enough for stock cars with factory hardware and ECU calibrations. However, the necked down design becomes a major flow restriction when ran with power upgrades such as cold air intakes, intercoolers, downpipes, and ECU upgrades. 

UPGRADE YOUR TURBO INLET PIPE

The IE Turbo Inlet Pipe helps you to get the most out of your IS38 or IS20 turbo and power upgrades by removing the factory flow restriction. The cast aluminum design allows for a constant diameter elbow increasing efficiency from the intake to the turbo without the bottleneck design of the factory unit.

INCREASED AIR FLOW

This Intake delivers an impressive flow increase to feed your turbo. More cold air flow means more power; especially during the hot summer months. Ditch your stock restrictive airbox for the IE intake System.

DESIGN DETAILS

IE engineers set out to produce the highest performing cold air intake that looks great and fits like a factory installed part in your A4. The latest in computer design and 3D scanning technology were employed during the development process for a perfect fit and maximum performance. The final product resulted in the greatest performing and best-looking intake available.

HIGH-FLOW VELOCITY STACK

Delivering cold air to your engine is a must for making power. The velocity stack efficiently channels air as quickly as possible into the intake system. The velocity also functions as a solid mount for the air filter which means no intake pipes rattling on heat shields.

CUSTOM HEAT SHIELD

IE uses a three piece heat shield which performs and looks great. It effectively channels cold air from the front of the car to the massive performance filter. Furthermore, it eliminates the induction of hot air found in other locations of the engine bay. A second heat shield is mounted above the turbocharger to further protect against power robbing heat off the exhaust and turbo.

PERFECT FITMENT

This Intake fits B9 Audi A4 and A5 without any modification or installation hassles. The install process is simple and can be done quickly with basic tools. The fact that IE intake utilizes the factory airbox mounts ensures a perfect and hassle free fit. Additionally, the stock rubber mounts allow for engine movement which keeps intake components from getting damaged.

CLASSY AND CLEAN APPEARANCE

Wrinkle black powder coated velocity stack and heat shields result in a sleek and sporty appearance in any engine bay. As a final touch, all IE heat shields are finished with a classy, laser etched, stainless steel IE logo badge.
