A cold air intake with a washable/reusable Pro 5R synthetic-media filter, replacing the factory airbox on 2017-2019 L5P trucks.
why this one — Fills the K2-HD-chassis L5P year gap (2017-2019) between the LML Momentum HD intake and the 2020-2026 Momentum HD intake in this catalog - same aFe Quantum-line design used across the Duramax lineup, priced lower than Momentum HD because it ships without a documented dyno gain for this application.
No dyno chart or hp/tq gain figure found published for this specific SKU on afepower.com at time of check - not invented.
