AEM (Advanced Engine Management) is proud to release its Brute Force HD intakes for diesel applications with a massive DRYFLOW filter element! AEM Brute Force HD intakes are available for popular late model Cummins, Duramax, and PowerStroke Diesel engines. We engineer our Brute Force HD intakes to deliver maximum air flow, filtration and durability for heavy duty applications and they even outperform the AEM BRUTE FORCE intakes for these vehicles in both dust holding capacity and filter flow. AEM's reusable DRYFLOW air filter for its Diesel applications is engineered to allow for longer service life and higher efficiency for maximum performance in between servicing (more DRYFLOW key features are below). Compared to the standard 9" Brute Force Dryflow Filter, the Brute Force HD Dryflow filter features over twice the surface area of filter media and utilizes deep, bull-nosed pleats to improve dust holding capacity and increase intervals between cleanings. The DRYFLOW does not use oil to trap dirt, which eliminates any chance of over oiling the filter element, taking the guesswork out of servicing your filter and dramatically reducing filter cleaning time. AEM manufactures its intakes from mandrel-bent, lightweight aircraft aluminum with high-strength dogbone brackets and dual rubber soft mounts for maximum durability, and includes a "bullet-proof" heat shield with a powdercoated black finish, a complete hardware kit and comprehensive photo installation instructions. Brute Force HD intakes are available with a silver powdercoat or mirror-polished finish.
- Increased Efficiency: AEM’s lifetime DRYFLOW Synthetic air filter is 99.4% efficient in FINE DUST testing, filters dirt as small as one micron, and never needs filter oil!
- DryFlow Technology: AEM's unique non-woven synthetic filter media never needs oil! This means less down time between cleanings and no more chance of over-oiling. It takes the guesswork out of servicing your air filter
- Durable Construction: An injection molded ABS plastic filter lid and base provide increased structural rigidity - it's virtually impossible to collapse!
- No mesh screen means no more filter damage from shipping, bumps during installation or cleaning
- Liftetime Filter: Element is cleanable and is Guaranteed for Life!
- Will not void your vehicle warranty!
| Q: | What is the Power Spacer and why is one not included in every BRUTE FORCE kit? |
| A: | The Power Spacer is a plenum spacer that installs in between the intake manifold and the throttle body. In about 5% of our applications, we have found that increasing plenum volume increases power. We test each system we develop with various Power Spacer designs, and only include Power Spacers in BRUTE FORCE intake systems when they improve performance. AEM Power Spacers feature a smooth internal design that makes more power and does not whistle the way spacers with screw type inlets do. Because they do not increase performance on every application and are designed to work specifically with BRUTE FORCE intakes, AEM does not sell them separately and includes them in kits when they increase power. BRUTE FORCE applications in our search results indicate whether a system includes a spacer. |
| Q: | I have a throttle body spacer and bought a BRUTE FORCE intake that does not include one. Should I continue to use it? |
| A: | No. We highly recommend removing the spacer prior to installing your BRUTE FORCE intake, as it will negatively affect the fit of the system on your vehicle and will not improve your truck’s performance. |
| Q: | Is the BRUTE FORCE intake a “cold air” system? |
| A: | Although it is not a cold air intake in the traditional sense (routing the air filter outside of the engine compartment), BRUTE FORCE intakes pull the air charge from the coolest source, making them in essence cold air designs. Because of the heavy duty and off road use many trucks encounter, we designed BRUTE FORCE intakes as underhood systems to protect them from potential damage. We use a steel heat shield when necessary to shroud the filter from engine heat, and perform extensive temperature testing to ensure the vehicle is receiving the coolest air charge possible (CLICK HERE for AEM’s temperature testing procedures). |
| Q: | Why do some BRUTE FORCE intakes not include a heat shield? |
| A: | We perform extensive temperature testing during the development phase to ensure that the filter is in a location that will receive the coolest air charge (CLICK HERE for AEM’s temperature testing procedures). For some BRUTE FORCE intakes, we found that there was no difference in inlet temperatures with and without a heat shield during our temperature testing. Since we do not to want you to waste your money on parts that are not necessary, we do not include a shield with these applications. |
| Q: | Why does AEM use aluminum for its intake piping? |
| A: | Our Chief Engineer John Concialdi provides an explanation of the difference between Aluminum vs. Steel vs. Plastic in inlet piping: The issue of heat absorption with an intake system has a degree of validity, however we have found that too much emphasis is placed on material selection, instead of the real issue of tuning the system. Our systems feature a unique shape and diameter because this is what we found to make the most useable torque and horsepower for each individual application in testing. However, for the purposes of this discussion, we will limit it to why we choose to make our systems from aluminum and the effects of heat absorption on all materials. If you do not wish to review all of this information right now, a quick synopsis of this discussion is outlined in the following bullet points, with complete topic discussions below:
We limit our use of plastic because this material absorbs some of the sound energy we work to create in the inlet duct. Although we use the best plastic material for our plenums, it is still not as resilient and does not retain the visual appeal of aluminum over long-term use. Because we have to use plastic on throttle body applications, we take extra precautions to ensure that the aluminum retaining ring that attaches to the throttle body is anchored securely into the plastic plenum; this is done by making an interlocking mechanical link between the plastic and aluminum. Whether or not an inlet system is made from aluminum, steel, or plastic, the thermal conductivity of the duct material has little effect on engine power. We have found that the tuning of the pipe, in addition to providing the coolest inlet air source, are the keys to making useable power. We perform engine inlet-air-temp studies when developing each application to determine the coolest location for sourcing inlet air. In addition to this, we determine the safest location for the inlet source to protect it from highly dusty conditions and water. To this end, we provide a stainless-steel heat shield to help minimize heat soak into the inlet area, as well as to provide protection from dust, dirt and mud. 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 do I order a polished BRUTE FORCE System? |
| A: | BRUTE FORCE part numbers include a two-letter suffix at the end. The “D” at the end of the suffix indicates that a DRYFLOW filter is included (which is standard for all BRUTE FORCE intakes), and a “P” indicates a polished finish (for example, 21-800DP is a polished BRUTE FORCE intake with a DRYFLOW filter). |
| Q: | How do I order a silver powdercoated BRUTE FORCE System? |
| A: | BRUTE FORCE part numbers include a two-letter suffix at the end. The “D” at the end of the suffix indicates that a DRYFLOW filter is included (which is standard for all BRUTE FORCE intakes), and a “C” indicates a clear silver powdercoated finish (for example, 21-800DC is a clear silver powdercoated BRUTE FORCE intake with a DRYFLOW filter). Powdercoated BRUTE FORCE intake systems are most popular with Jeepers because it is an easier finish to maintain, and Diesel enthusiasts because the Zirconia-based powdercoat helps the inlet pipe deflect heat soak. |
| Q: | What factory components do BRUTE FORCE or Workhorse Diesel intakes replace? |
| A: | BRUTE FORCE Diesel intakes replace all of the factory components from the turbo inlet to the factory air box. This typically includes the stock airbox, stock inlet hose and stock breather hoses. In some cases AEM retains the factory breather hoses, as indicated in the instructions. AEM includes complete hardware and photo instructions for a trouble free installation. |
| Q: | What factory components do BRUTE FORCE intakes replace for gas engines? |
| A: | BRUTE FORCE intakes replace all of the factory components from the throttle body to the factory air box. This typically includes the stock airbox, stock inlet hose and stock breather hoses. In some cases AEM retains the factory breather hoses, as indicated in the instructions. AEM includes complete hardware and photo instructions for a trouble free installation. |
| Q: | I have a body lift on my truck. Will it affect the fit of a BRUTE FORCE intake? |
| A: | Yes, a body lift will negatively affect the fitment of the intake unless an engine mount lift is installed to maintain proper geometry of the engine to the chassis. Most BRUTE FORCE intakes mount to the throttle body inlet and the chassis via a soft, flexible mount. If the body is lifted, the mounting points will not align correctly. |
| Q: | I have a suspension lift on my tuck. Will it affect the fit of a BRUTE FORCE intake? |
| A: | No. Suspension lifts do not affect engine-to-chassis geometry and therefore will not affect the intake fitment. It will install the same as if the truck has a factory suspension set up. |
| 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 the warranty on my BRUTE FORCE intake? |
| A: | 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. This warranty is limited to the repair or replacement of the AEM part. In no event shall this warranty exceed the original purchase price of the AEM part nor shall AEM be responsible for special, incidental or consequential damages or cost incurred due to the failure of this product. Warranty claims to AEM must be transportation prepaid and accompanied with dated proof of purchase. This warranty applies only to the original purchaser of product and is non-transferable. Improper use or installation, use for racing, accident, abuse, unauthorized repairs or alterations voids this warranty. AEM disclaims any liability for consequential damages due to breach of any written or implied warranty on all products manufactured by AEM. |
