INCREASE POWER AND SOUND WITH A COLD AIR INTAKE

The IE Audi B9 A4 & A5 2.0T Cold Air Intake is the perfect addition to any engine bay. Give your Audi added horsepower, torque, snappier throttle response, and an aggressive sound. Typical peak gains from our CAI are roughly 10-20 Horsepower and Torque.

POWER GAINS

The ram air design, velocity stack, and massive 55-inchfilter inlet help deliver the most HP possible from a cold intake system.

Expect peak gains of 10-20+HP/TQ on tuned engines.

INCLUDED IN THE B9 IE CAI KIT

• IE Intake velocity stack & heatshield assembly
• IE Silicone turbo inlet pipe assembly
• IE 5” inlet performance air filter
• IE Turbo heat shield
• All necessary hardware (clamps, nuts, bolts, etc)

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

Installation is a quick and easy install with basic tools. The process should take around an hour for most enthusiasts. CLICK HERE to view and download the IE B9 Cold Air Intake Install Guide.

DYNO POWER RESULTS

The following power result data was collected on our in-house Dynapack hub dyno. Dyno chart is as tested at 4500 feet altitude with SAE corrected numbers. Before and after results are direct back-to-back comparisons on a full bolt-on stage 2 B9 A4 2.0T engine. The only change made to the vehicle between testing is the swap from a stock intake with a new clean air filter to the IE Cold Air Intake Kit. Dyno power results are approximate and may vary from car to car.

CTS Turbo is proud to announce our new intake system for the B9 AUDI A4, AllRoad, A5, S4, S5, RS4, RS5 (2017-2019 models)

We designed our system to work in conjunction with the OEM air scoop to seamlessly force cold air into the air intake system. Air then flows through our high flow 6″ velocity stack air filter for maximum engine performance.

Our single-piece proprietary moulded silicone couplers allows for smooth entry of air into the engine providing peak power gains ranging from 10-12HP on a stock car.
All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound. Turbo spool up and diverter valve release are a lot louder!

Features:

• Massive 6″ velocity stack filter, largest on the market
• 3.5″ silicone turbo inlet hoses for both 4-cylinder and 6-cylinder engines (5-ply construction, will not collapse)
• Heatshield to keep air temperatures as low as possible
• Easy install and perfect fitment
• Increased engine performance, less turbo lag
• Sporty sound under acceleration and loud pressure release
• Gains of 10-12HP on stock vehicles, tuned cars will gain even more!
• Kit comes with parts to install on 1.8T, 2.0T, 2.9T and 3.0T engines (fits MAF-LESS cars)

THE QUALITY POLYMER INTAKE

This cold air intake is manufactured from a high-quality rotomold procedure that produces a superior plastic material with consistent wall thickness, strong corners, and excellent heat resistance. Enjoy a proper motorsport-designed intake system without compromise.

PERFORMANCE FIRST

The internal volume of the intake and its complex shapes are the results of application-specific engineering for the Audi B9 platform. Every inch has been performance designed to feed your turbocharger with the most airflow possible.

THROTTLE DOWN, SOUND ON

The stock airbox on your Audi A4 or A5 2.0T has been manufactured to silence all engine and turbo sounds at any performance cost. Upgrading your air system with an IE polymer intake will release a symphony of engine throttle, spool, and blow-off sounds that will be music to your ears.

MULTIPLE PRESSURE ZONES

This intake features high and low pressure zones to feed the turbocharger and engine demands for any power goal. The majority of fresh air supply is supplied to the filter from the grill. If additional air demands are required, the intake will pull low-pressure air through the filter cover as needed.

BUILT-IN VELOCITY STACK

The integrated velocity stack smooths the airflow from the large filter into the charge system with excellent laminar properties. This powerful design detail results in a very high inertia flow with reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger.

PRECISION DESIGN

3D scanning tools are leveraged to create a high-resolution digital environment allowing our engineers to take advantage of all available space for a complete performance design while ensuring a hassle-free install.

ADVANCED SOUND TUNING

IE engineers elected to use a resonator in the B9 A4 & A5 exhaust. The result was a much better sounding exhaust overall. The factory cat back has a very unpleasant rasp when used with a downpipe which does not have a resonator. As IE engineers are true enthusiasts as well, it was very important that the exhaust also sounded great. Check out the video to hear stock vs. IE sound clips.

*All sound clips are on a Stage 2 vehicle with IE cold air intake and intercooler installed. Only the downpipe was changed, no modifications were made to the factory installed catback.

HIGH-FLOW CATALYST

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.

QUALITY CAST SECTIONS

Typical aftermarket downpipes use bends or cuts to form the shape of the downpipe; this allows the use of larger piping, but sacrifices flow and often times fitment. Using specialized 3D scanners and software, IE engineers can design odd shapes and sizes to maximize flow and conform into tight spaces without any sacrifices. To accomplish these shapes, sections of the dowpipe are cast manufactured from the digital models. The result is an incredibly high-quality performance unit with a perfect fit and beautiful finish.
