AEM Workhorse HD Diesel Intakes

Workhorse HD Diesel Intakes FAQs...
AEM (Advanced Engine Management) is proud to release its Workhorse HD intakes for diesel applications with a massive DRYFLOW filter element! AEM Workhorse HD intakes are available for popular late model Cummins, Duramax and PowerStroke Diesel engines. We engineer our Workhorse intakes to deliver maximum flow, filtration and durability for heavy duty applications and they even outperform the company's 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 Workhorse 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 overoiling the filter element, takes the guesswork out of servicing your filter and dramatically reduces 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. Workhorse HD intakes are available with a silver powdercoat or mirror-polished finish.

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!
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
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
Element is cleanable and is Guaranteed for Life!
Will not void your vehicle warranty!

Q: What is the warranty on my AEM 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.
