High-Performance Intake Upgrade for GM 6.6L Duramax L5P

If you're looking to give your 2020-2025 GM 6.6L Duramax L5P a serious boost in airflow without over-complicating the install, the aFe Momentum HD Cold Air Intake with the Pro DRY S filter is a solid upgrade. Right out of the box, it’s designed to increase performance by replacing the restrictive factory intake system with a larger, smoother, and more efficient setup. You'll notice quicker throttle response, improved airflow, and a cleaner, more refined engine tone the moment you hit the road. What makes this intake stand out is its oversized, oil-free Pro DRY S air filter. It’s a three-layer synthetic media filter that captures dust and debris effectively without sacrificing airflow. Maintenance is simple—just rinse and reuse. The filter itself is housed in a one-piece XLPE (cross-linked polyethylene) enclosure, which helps block engine heat and keeps incoming air cooler and denser. A built-in clear sight window means you can check filter condition in seconds, no tools or disassembly required.

High-Flow Intake Tube with Simple Install

The intake tube is computer-designed and dyno-tuned to deliver the best flow possible while maintaining a factory-tight fit. Paired with premium stainless T-bolt clamps and a reinforced silicone coupling, this system is built to hold up under pressure, even in high-performance applications. Factory air scoop inlets are integrated into the design, and there’s even an auxiliary inlet if you want to pull in additional air for aggressive setups. Additioanlly, installation is straight-up plug and play. It uses existing mounting points, so you won’t need to chop or modify anything under the hood. Most users can get it installed in under an hour with basic tools.
