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.
