TECHNICAL DETAILS

Prevent crankcase oil fumes from condensing and filling your turbo piping, intercooler, and intake manifold. The simple to install and quality looking IE catch can kit is a must for your VW MK5 & MK6 2.0T TSI engine.

A catch can works well to catch all of the oil fumes that are omitted from the valve cover breather, removing the faulty factory oil separator in the process. This not only removes the oil mist that is found everywhere but will greatly help reduce carbon buildup on the intake valves, a common problem on TSI engines, which relates to power loss and poor drivability.

Our kit includes the necessary valve cover breather adapter to remove the separator and plumb the catch can using the two included -10AN hoses. Using our catch can kit, you are not required to remove any of the emissions system or vent the catch can to the atmosphere, which can cause oil mist build-up in your engine bay. Our breather plate simply installs in place of the factory plastic breather plate located on top of the valve cover, while the catch can mounts to a custom bracket easily accessible on the passenger side of the vehicle.

This kit uses the Integrated Engineering billet recirculating catch can, which features our state-of-the-art baffle system to catch the oil mist and not let it pass back into the turbo inlet. This flawless catch can is fully serviceable, easily disassembling if needed. Draining the catch can is simple with the use of the included T handle drain valve, no tools necessary. This beautiful piece is finished with a bright black anodize finish, which maintains a stealthy appearance while looking great in your engine bay.

Everything you need to upgrade the PCV system on your Audi B8 2.0T TSI engine is included with this kit, with a very simple installation that takes less than an hour to install on average. This kit allows the use of the factory engine cover if desired, and the entire install is completely reversible if it ever needs to be removed for any reason.

COLD WEATHER CLIMATES

Catch can kits are designed for warm weather climates only. If you live in an area with sub-freezing temperatures in winter months, extra precaution must be taken as condensation in the catch can and lines can freeze and cause pressure to build up in the crankcase. We recommend checking the contents of the catch can frequently or removing the system entirely during cold winter months. Integrated Engineering is not responsible for any damage caused by improper servicing of the catch can.

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.

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.

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.
