GMC Sierra 1500 Performance Air Intake - Airaid - Cold Air - `20-`21. This Airaid cold air intake is built to replace the factory intake on compatible 2020–2021 Sierra 1500 models and improve airflow quality while retaining a protected, enclosed filter location.

The system uses a CAD-designed intake tube to reduce restriction and accelerate airflow into the engine, paired with an enclosed air box to shield the inlet and filter from engine bay heat and debris. It includes a washable, reusable oiled SYNTHAFLOW air filter that captures contaminants while allowing high flow. The design is bolt-on and intended to maintain proper air-to-fuel ratios without the need for recalibration after installation, making it a straightforward upgrade for enthusiasts who want reliable, usable performance and easier servicing.
