2025-2026 Duramax Banks Ram-Air Air Intake System (42297)

Fits

Brand new for the 2025 Duramax L5P platform, this Ram-Air intake is built to work around the new crank case ventilation monitoring added to the factory intake system. The enclosed airbox helps block hot underhood air and connects to the OEM hood and forward ram air scoops for improved airflow at speed. An extra side inlet opens to the wheel well for additional fresh air and a stronger induction sound.
