With the exhaust system flowing better performance gains be achieved. Turbo lag should also be reduced as an added benefit. IE engineers guarantee a perfect fit by designing all IE downpipes in-house using the latest technology. Digital scanning is using to scan the entire environment which ensures that there is proper clearance and that all mounting points are in the correct location. Manufactured from 304 stainless offers a life-long product that brings performance and fun to the table for years to come. POWER GAINS The most power gains will be achieved when the IE Downpipe is paired with IE matching software, air intake, and FDS intercooler. SOUND TUNING An aggressive and drone-free sound will be emitted from the IE Cast Downpipe. This should be music to your ears! Thick wall tubing and cast sections remove much of “tinny” sound emitted by cheaper, thin wall, downpipes. With downpipes, you get what you pay for in terms of sounds and overall manufacturing quality. HIGH-FLOW CATALYTIC CONVERTER IE’s performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced. DIRECT BOLT-ON WITH PERFECT FITMENT The IE downpipe replaces over 6 feet of restrictive factory exhaust tubing, all the way back to the OE “Cat-Back” rear section. Sturdy fabricated mounts and precise engineering result in a rattle free and long last replacement exhaust system. 3D scanning systems were employed to ensure perfect placement both in pre and post-production phases.

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.

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.

EASY INSTALLATION
