Banks Ram-Air Cold Air Intake System for Chevy/GMC (2025-26) 6.6L Duramax L5P (Oiled Filter)

The Ram-Air intake system for the 2025-26 Duramax 6.6L widens the powerband, sharpens turbo response, and improves fuel economy by improving air mass flow to the turbo. This is made possible by our patented Banks Air Mass Control Module and Crankcase Ventilation Control Modules. Meanwhile, all competitors must retain near stock airflow or risk setting a check engine light.

Fitment Note:
Ram-Air is not compatible with catch cans including VSE.

Specifications:
Brand new for the 2025-26 Duramax L5P platform, the Banks Ram-Air intake is a game-changer. With the 2025 model year Duramax engines, GM added a new sensor into the intake system to monitor Crank Case Ventilation Pressure. To get past this airflow limitation, we engineered a new patented Air Mass Control Module and a Crankcase Ventilation Control Module that allow the intake to go beyond these limitations for truly unmatched airflow performance.

With a Big-Ass filter, huge induction tube and a unique bellowed silicone coupler to allow for engine movement while tapering down to increase air density, your 6.6L engine will breathe easy and cleanly. Its enclosed housing keeps power-robbing heat away and attaches to the OEM hood and front ram-air scoops for even better performance at speed. An extra side inlet opens up to the wheel well for fresh air and a pleasant induction sound.
