The GM Duramax L5P Turbo Intake Horn is a high-performance upgrade designed to replace the fragile plastic factory turbo inlet on 2017–2025 GMC Sierra and Chevy Silverado HD trucks with the 6.6L Duramax L5P engine. Built from durable steel and finished in a sleek black powder coat, this intake horn delivers improved airflow, durability, and compatibility with both stock and aftermarket turbos.
