Banks L5P Complete Airflow Upgrade Bundle 2020-2026 Duramax 6.6L

Upgrade the complete intake and charge-air path on your 2020–2026 Chevy/GMC 6.6L L5P Duramax with this Banks Complete Airflow Upgrade Bundle.

This package combines three of Banks’ most popular airflow upgrades — the Ram-Air Cold Air Intake, Monster-Ram Turbo Inlet Elbow, and 3.5-inch Boost Tube Upgrade Kit — into one complete package.
