Banks Power Ram-Air Intake System with Oiled Filter for 2020-2023 Chevy/GMC 2500/3500 (6.6L) 42266

Fits select 2020-2023 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD models (6.6L L5P Duramax).

The Banks Power Ram-Air Intake System (MPN 42266) addresses the restrictive induction tuning of the 2020-2023 L5P Duramax. This system includes the patented Banks Air Mass Control Module (US Patent #11,193,441), which allows for an oversized intake tube without triggering check engine lights. The massive SuperTube and large-capacity airbox provide a 58% gain in air mass flow over the stock assembly, improving turbo response and engine efficiency.

Built for durability and performance, the system features a two-piece XLPE airbox and a unique EPDM bellows coupler. This design allows for natural engine movement while maintaining a secure seal. The enclosed airbox connects directly to the OEM hood and front ram-air scoops to draw in cool, dense air while shielding the filter from power-robbing engine heat.
