AEM pioneered the cold air induction system for sport compact cars in 1994. 

A cold air intake system relocates the filter outside of the engine compartment to deliver cool air inlet temperatures. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver large power gains. We also monitor fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light.

Every AEM cold air induction system features high standards of construction and AEM are is confident in their fit and performance that AEM guarantee them for the life of your vehicle. All AEM cold air systems include a lifetime DRYFLOW synthetic air filter and come with a limited lifetime warranty.

The European segment within the Sport Compact community has made a huge impact in the automotive scene. Exciting releases from renowned Euro manufacturers have helped to fuel the Euro markets popularity to another level. Such releases include the 1-Series BMW stuffed with a six-cylinder twin-turbo engine and the V8-powered E92 BMW M3. Even a couple years back, Volkswagen stirred up the industry with their R32 while Audi showed what dreams are made of with the Audi R8.

Along with great cars, the Euro community brings a style that is proprietary to their clique as well. Often times, this Euro-inspired look ignites others in the sport compact community to adopt the Euro style or technique of tuning. A handful of key Euro styling trademarks are now considered mainstream to import and domestic enthusiasts alike. Extremely clean lines, subtle exterior arrangements, ridiculously-low ride heights and aggressively-deep offset wheels are all style queues that we can thank the European enthusiasts for.

Another gift that came from the Euro scene in the mid nineties was the compact Audi A4. Since the German car manufacturer introduced the A4 model in 1994, the A4 has become a staple in the European car lineup. The A4 chassis is offered in a variety of configurations. It is available in front-wheel drive or in Audi's ''Quattro'' permanent four-wheel drive system. The A4 is also available as a sedan (saloon), a wagon (Avant), and previously as a convertible (Cabriolet). Performance spinoffs of the A4 are also offered, such as the slightly higher performance Audi S4 and of course the race inspired Audi RS4.

For enthusiasts looking to get into a European vehicle, the 2005-2008 (B7 chassis) of the Audi A4 is a great option. The popular engine choice for the B7 would be Audi's 2.0-liter turbocharged FSI (Fuel Stratified Injection) powerplant. This engine features an increased power output from previous years bringing power up to 200 horsepower. An excellent way to increase the performance of the Audi A4's 2.0 TFSI engine is AEM's newly-released Cold Air Intake System.

AEM's Cold Air Intake System for the 2005.5 (from 5/05) to 2008 Audi A4 2.0L is CARB exempt for these models which means it is 50 state street legal.  The intake features a semi-closed heat shield design, a powder coated gun metal gray finish, and a DRYFLOW air filter. AEM engineers created a heat shield that fits snugly into the space between the right headlight and exhaust manifold with the turbocharger. The engineers also took the extra step of molding a heat shield that fits both HID headlight equipped and non-HID headlight equipped models. To withstand the high engine bay temperatures seen under the hood of the Audi, AEM has covered the heat shields in a durable powder coated black finish. Connecting directly to the turbo inlet, the AEM kit includes a smooth mandrel-bent aluminum inlet pipe that replaces the restrictive factory equipment from filter to turbo. Once the intake pipe is connected to the turbo inlet with the supplied transition coupler, the other end is topped with an AEM DRYFLOW performance air filter. The air filter's construction consists of an inside diameter of 2.75-inches (70mm) by a height of 5.25-inches (133mm). Another nice feature of the AEM Audi A4 intake is the retention of the factory fresh air duct which draws in cool air from the front fascia of the A4.

AEM Air Induction Systems

Quick Tips for Cold Air System Installation:

With so many new applications available through AEM, we recommend reviewing the instructions for your system thoroughly prior to installing an AEM Air Induction System. This will save you time.

Do NOT completely tighten the fittings and connections down for your AEM Air Induction System until the end of the installation. Although each system is precision engineered and fits exactly the same way on each application, it is sometimes necessary to maneuver the system to its mounting points during the installation process. Tightening all of the clamps and brackets as you go will make this procedure difficult, so you should make them snug enough to hold the position of the intake system and only tighten all fittings and connections once everything is installed and the position of the system is properly aligned.

What is a C.A.R.B. E.O. number?

Most AEM intake systems either carry an exemption or have been submitted to the California Air Resources Board for an Executive Order (CARB EO) number, exempting them from the prohibitions of California Vehicle Code (CVC) 27156, which states that you cannot modify your car in the area of the emission control system. The C.A.R.B. E.O. number allows you to legally use the AEM intake system on your car.

What’s the Difference between a Cold Air System (CAS) and a Short Ram (SRS)?

In most cases a CAS will out perform a SRS. AEM emphasizes developing power in the lower to mid range of the power band, since this is the area of the power band typically used in daily driving. A CAS is typically longer and places the air filter outside of the engine bay to achieve ambient inlet air temperatures. A SRS places the air filter under the hood and uses a shorter inlet pipe than the CAS. In some cases, the SRS is preferred over the CAS due to inlet tract length tuning. The power advantage gained by using the correct diameter and length of tube negates the advantage of cooler inlet air in these cases. In these instances AEM only offers SRS because there was no advantage to using the CAS.

Will an AEM air intake void my new car warranty?

NO. The only time this can happen is from improper installation that causes damage to a vehicle system. If a service technician denies your warranty claim ONLY because the car is modified with an AEM intake system and the vehicle system failure was not a direct result of the installation and use of an AEM intake, please refer him to the Magnusson Moss Warranty act.

What does the soft mount do and how important is it?

The majority of AEM air intake system designs mount to a vehicle in two locations. One mounting location is to the engine at the throttle body and the “cold"" or filter end of the inlet pipe mounts to the body of the car. The movement of the engine on the engine mounts allows it to rock inside the engine bay, so we compensate for engine motion by using a soft mount that provides a flexible link for the inlet pipe between the engine and the body of the car. If you do not install the soft mount properly the inlet tube may break at the bracket weld and void the warranty on the intake system. Our instructions provide a detailed diagram of proper installation of the soft mount, and are viewable from the search results page for each application.

I have an engine swap. Which intake should I use?

AEM manufactures hybrid intake systems for some Honda and Acura models with popular engine swaps. These intakes are a direct fit and fully warranted. For cars with other engine swaps, we do not recommend using our intake because of potential fitment problems. If you elect to purchase an AEM intake for your engine swap application, we cannot guarantee proper fitment and any modifications to the intake system will void the manufacturer warranty.

What is the warranty on my AEM intake?

AEM warrants that its intake systems will last for the life of your vehicle. AEM will not honor this warranty due to mechanical damage (i.e. improper installation or fitment), damage from misuse, accidents or flying debris. AEM will not warrant its powdercoating if the finish has been cleaned with a hydrocarbon-based solvent. The powdercoating should only be cleaned with a mild soap and water solution. Proof of purchase of both the vehicle and AEM intake system is required for redemption of a warranty claim.

AEM DRYFLOW Air Filters

What makes the DRYFLOW filter better than oiled cotton-gauze filters?

DRYFLOW filters have several features that make them better than cotton-gauze. Typical DRYFLOW air filters have a better filtering efficiency than cotton-gauze filters.  Also the cleaning process doesn't include oil for DRYFLOW air filters.  This removes the mess and question of how much oil to put on the filter.

What is the DRYFLOW filter made of?

The DRYFLOW filter is made from a single-layer of pre-pleated polyester synthetic filter media with a nylon-reinforced internal cage for added structural rigidity. For conical filters, the base and cap are made from polyurethane, which will not shrink or crack. Our Brute Force HD Diesel oval filters use deep pleats and Zytel 15% GF plastic for the cap and base. This construction assists in the overall structural rigidity (oval Diesel DRYFLOW filters use 12.5 square-feet of media for maximum flow, approximately 1350 CFM).

Will the DRYFLOW filter affect my warranty?

DRYFLOW air filters will not void your vehicle warranty.

How long will a DRYFLOW filter last?

If you clean and maintain your DRYFLOW filter, it will last for the life of your vehicle.

Does AEM make panel DRYFLOW filters for factory air boxes?

Yes, DRYFLOW Performance Panel Filters are now available for some models. 

I have a competitor intake or AEM intake with an oiled filter. Can I upgrade to the DRYFLOW filter?

Whether you own an AEM intake system or competitor intake system, we encourage you to upgrade to the DRYFLOW air filter. The DRYFLOW delivers one of the highest filtration efficiencies available in an aftermarket performance air filter, and because you do not have to oil it, all the guesswork associated with servicing an oiled cotton gauze filter is eliminated.

How well does the DRYFLOW filter flow?

We design our DRYFLOW filters to exceed the flow requirements for the size of the engine that we designed the air intake for. Rest assured that we have taken flow into account for all of our intake designs and our DRYFLOW filters will deliver more than adequate flow for your vehicle.

Does the DRYFLOW filter flow as well as cotton-gauze elements?

Our DRYFLOW filter flows nearly as well as cotton gauze elements. In order to increase flow we add more pleats that are ¼"" deeper than much of the competition. Keep in mind that the DRYFLOW air filter typically has a higher filtration efficiency than a cotton-gauze air filter. It provides great filtering and provides air flow well beyond the requirements of your engine.

How often should I clean the DRYFLOW filter?

Frequency of cleaning for your DRYFLOW filter will depend on the conditions in which you drive. As a rule, we recommend that you clean your filter a minimum of every 30,000 miles, inspect it during oil changes and regular service intervals, and clean it if it appears to be reaching its dust holding capacity. If you live in particularly arid, dusty climates or venture off road, we recommend cleaning the filter every 3,000-5,000 miles.

How long does it take to clean the DRYFLOW filter?

The DRYFLOW filter media is hydrophobic, which is a fancy way of saying it does not soak up water. Under normal conditions, cleaning will take about an hour.

Is it necessary to oil my DRYFLOW filter?

NO! The DRYFLOW filter NEVER requires filter oil to trap dirt. It typically filters at a higher efficiency than oiled filters and blocks harmful dirt particles.

Will frequent cleanings affect the DRYFLOW filter's longevity?

No. The DRYFLOW filter’s polyester synthetic media can endure repeated cleanings without significantly degrading the media’s filtration capabilities. If you clean and maintain it properly it will last for the life of your vehicle.

What can I do if I am on the trail and need to clean my DRYFLOW air filter?

DRYFLOW filters for all of our intake systems exceed the flow requirements of the engine for extended service and we highly recommend cleaning them per the instructions in our Filter Cleaning System (Part number 21-110). If you feel you must clean the filter and do not have a cleaning system available to you, we suggest hitting it several times to knock the dirt off of the filter pleats and servicing your filter per AEM specifications as soon as possible. If it is absolutely necessary, use fresh water to rinse mud or heavy dirt off the element from the inside out to ensure the dirt does not wind up inside the filter, and clean the filter per AEM specifications as soon as possible.

Can I use a different type of cleaning solution on my DRYFLOW filter?

To ensure optimum performance and filtering capabilities, use AEM’s Filter Cleaning Solution (part number 21-110) or a mild multi purpose cleaner.

What is the warranty on my DRYFLOW air filter?

AEM warrants that its DRYFLOW Air Filter will last for the life of your vehicle.

What is a DRYFLOW Air Filter?

The AEM DRYFLOW air filter is constructed of gradient non-woven polyester fibers that are several layers deep, and as the name implies, it is a very efficient air filter that does not rely on oil to capture airborne contaminants from the inlet air stream. The DRYFLOW air filter is not a single layer barrier filter but rather a depth loading filter where the contaminant is captured through several layers of fibers.

How do we perform filter efficiency tests?

We use ISO 5011:2000 with ISO “A-2 Fine Dust"" as the contaminant. Southwest Research Institute performs the testing and determines flow rate criteria based on the average flow requirements of a typical engine on which the filter to be tested will be used. The concentration of the contaminant introduced into the air stream is significantly higher than what would be encountered in normal use in order to perform the test in a reasonable time. Typically, 2 flow rates are used for testing. 160 CFM is used for smaller displacement engines. 240 CFM is used for larger displacement engines.
