If you're looking to add brute power to that truck of yours, we've got what you need! The Brute force cold air intake system from AEM was specially designed for popular SUVs, trucks and muscle cars.
Brute Force aftermarket air intake systems are dyno-tuned and proven to add horsepower & torque on large engines. The plumbing is specially designed so that the filter pulls air from the coolest of locations within the engine compartment. The inlet pipe which carries the cool air is engineered with perfection, allowing more air to travel to the intake valves. Equipped with a powder coated steel shield, the high quality filter is protected from road dirt/grime as well as engine heat.
AEM Brute Force cold air intake systems are available for gas and diesel engines. The added horsepower and torque is what sets this performance intake system apart from the competition. So buy yours today and watch your engine perform the way you've always wanted.
Frequently Asked Questions
|Q:||What is “soft mount” and is it important?|
|A:||Most engines fluctuate when acceleration is applied, so the soft mounting system compensates for that motion. It is a link for the inlet pipe that sits between the engine and the body of a car. If the soft mount isn’t installed correctly your intake pipe could essentially break.|
|Q:||Why is aluminum used when making the intake piping?|
|A:||The issue of heat absorption with an intake system is quite valid, but they found that too much focus is placed on material selection and AEM focuses mainly on performance. The systems shape and diameter are unique and this is what most improves horsepower and torque. Here is a quick synopsis of why we use aluminum:|
AEM performs engine inlet air temp studies when designing each system, determining the coolest area for inhaling cool air. They also determine the safest location for the source, protecting it from dust and water.
At light throttle opening, air speed and airflow at the inlet system are relatively low. The high residence time of air in the inlet while at low-throttle settings will increase inlet charge temps when materials with high thermal conductivity are used. Typically, when someone is at light throttle they are not asking the engine to make power. Most likely, fuel economy is the issue.
When the throttle is fully opened however, air speed and airflow increase considerably. Typically, the inlet air speed of a 5.7L engine with a four-inch duct at full throttle is 34 feet-per-second, based on a volumetric efficiency of 70% and an engine speed of 3,000 rpm. Most inlet systems for every intake manufacturer for this engine are 30 inches or less. This means that the air in the duct of a 30-inch inlet length on this engine at the given rpm is 1/10th of a second—hardly enough time to transfer an appreciable amount of heat into the air stream on any system.
Basically, the rate at which air travels through the inlet path under open throttle, when one is asking the engine for maximum power, negates the effect of material heat soak, regardless of the material. We hope that this helps to clear up the issues of material heat absorption in intake systems.
|Q:||How would I go about ordering a silver powdercoated system?|
|A:||The part numbers feature a 2 letter suffix at the end. The “D” at the end indicates that a Dry Flow filter is included (standard for all Brute Force Intakes), and a “C” indicates the silver powdercoat e.g. 21-800DC.|
|Q:||What factory components does this system replace?|
|A:||The intake system replaces all components including the inlet, airbox and hoses. In some instances the breather hose is retained by AEM.|
|Q:||Will a body lift kit affect the intake system?|
|A:||The body will affect the lift kit in a negative way, unless there was an engine lift mount installed for proper geometry. Most intakes mount to the throttle body and chassis and if the body is lifted it won’t line up correctly.|
|Q:||Will a suspension kit affect my intake system?|
|A:||A suspension kit will not affect the engine to chassis geometry and will not affect the fitment.|
|Q:||What is a C.A.R.B. E.O. number?|
|A:||AEM intake systems carry or are pending approval for a California Air Resources Board 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 install and use the AEM intake system on your truck.|
|Q:||What is a power spacer and why isn't this system included into every kit?|
|A:||It is a plenum which installs between the throttle body and the intake manifold. In 5% of our applications, increasing the plenum increases power. AEM has tested the systems with different designs of power spacers and only include them in systems when they improve overall performance. These spacers provide a smooth internal design which adds power and does not whistle. They don’t increase performance on every vehicle and are only made for the Brute Force, so AEM doesn’t sell the spacer separately.|
|Q:||How to order a polished system?|
|A:||These intake systems include a 2 letter suffix at the end. The “D” at the end of the suffix means that a Dry Flow filter is included (standard for Brute Force) and the “P” means polished finish e.g. 21-800DP.|
|Q:||Will a Brute Force system void my vehicles warranty?|
|A:||The only time an AEM intake system will void your warranty is when there was an improper install. If a service technician tries to deny warranty because of one of these systems and the failure wasn’t a direct result because of it, refer them to Magnusson Moss Warranty act.

|Q:||Is this system considered a cold air intake system?|
|A:||This isn’t a cold air system by the traditional definition, but they are positioned to get the coolest air available on each application. AEM has implemented extensive testing to assure that the filter is positioned perfectly, sucking only the coolest air available.|
|Q:||Why do some intake systems not include a heat shield?|
|A:||For some applications, they have found that there was no difference in the temperatures with or without the shield. And having a shield present when it’s not needed would only waste your money.|
