A cold air intake with a reusable Pro 10R cotton filter and a sealed housing that replaces the factory airbox on the current-body Sierra HD, covering both the pre- and post-2024 L5P.

why this one — The current Momentum HD kit aFe builds for the 2020-2026 Sierra HD, with a published dyno figure (+16 hp, +44 lb-ft) and a stated 710 CFM flow number. Honest downsides: the gain is smaller than the older LML kit claims, and aFe marks this one not for sale or use in California, so a CA-registered Sierra should skip it.

where the number comes from

AFe product page states "Dyno-Proven Gains up to +16 HP and +44 Lbs. x Ft. TQ" and "Measured Flow: 710 CFM @ 7in H2O" for this exact SKU.
