Give your 6.6L Duramax LLY diesel engine a performance boost with AEM’s Brute Force HD intake with a massive Dryflow air filter. AEM Brute Force HD intakes are engineered to deliver maximum flow, filtration and durability for heavy duty applications and they even outperform AEM’s popular BRUTE FORCE intakes in both dust holding capacity and filter flow.

Key Features

• Proprietary AEM washable and reusable oil-free Dryflow performance air filter
• High-quality hose clamps for easy installation
• High-quality couplers are designed to not crack, fade or fail
• Available in gunmetal grey or polished white finishes
• Precision-made MAF adapters provide factory-like fit and prevent check engine lights
• Reinforced TIG-welded “Dogbone” chassis mounting brackets with dual soft anti-vibration mounts

AEM’s reusable Dryflow air filter for diesel applications is huge. Compared to the standard 9 Inch Brute Force Dryflow Filter, the Heavy Duty Dryflow filter features over twice the surface area and utilizes deep, bull-nosed pleats to improve dust holding capacity and increase intervals between cleanings. Best of all, AEM’s Dryflow air filter doesn’t use oil to trap dirt so it takes the guesswork out of cleaning and servicing your filter.

AEM manufactures its BruteForce HD intakes from mandrel-bent, lightweight aluminum with high-strength dogbone brackets and dual rubber soft mounts for maximum durability. This kit comes with a complete hardware kit and comprehensive photo installation instructions. Brute Force HD intakes are available with a gunmetal grey powdercoat or mirror-polished finish

AEM Brute Force Heavy Duty Intake 21-9022 is CARB Exempt, meaning it is street legal for use in all 50 U.S. states. This kit fits all Chevy Silverado and GMC Sierra 2500 and 3500 pickup trucks with the 6.6L Duramax LLY engine from 2004.5 through 2005.
