Product Description

The aFe Momentum HD Cold Air Intake System (Part #50-70056T) with Pro 10R pre-oiled filter is a performance-oriented upgrade designed for **2020-2025 Chevrolet Silverado and GMC Sierra 2500/3500 HD** trucks equipped with the 6.6L Duramax L5P turbo diesel engine. Featuring a large, ten-layer cotton gauze Pro 10R filter, this intake delivers significantly increased airflow and filtration capacity while maintaining excellent dust holding ability for extended service life. The sealed heat-resistant XLPE housing and patented filter-to-housing interface work together to draw cooler, denser air into the engine, improving throttle response and power potential.

With a dyno-tuned intake tube, premium stainless-steel hardware, and a direct-bolt-on design that uses existing factory mounting points, installation is straightforward with no cutting or drilling required. Measured airflow gains of approximately 710 CFM and dyno-proven increases of up to ~+16 HP and ~+44 lb-ft torque over the restrictive factory intake make this system an excellent upgrade for Duramax enthusiasts. A large clear sight window allows quick visual inspection of the filter without disassembly, simplifying maintenance. Note that this intake is **not CARB exempt or compliant**, so it cannot be used in California or other CARB-regulated states.
