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

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

Unlock the performance potential of your L5P Duramax with the Banks Power Ram-Air Intake System. Modern GM induction tuning has narrow tolerance ranges, which typically limits aftermarket intake diameter. Banks overcomes this with the patented Air Mass Control Module (US Patent #11,193,441), allowing for a massive SuperTube design that significantly outperforms the stock setup and competitors without triggering a check engine light.

This system features a "Big-Ass" oiled filter and a two-piece XLPE airbox that shields the intake charge from engine bay heat. The design integrates directly with the OEM hood and forward ram-air scoops to capitalize on high-velocity air at speed, while an additional side inlet draws fresh air from the wheel well. A specialized EPDM bellowed silicone coupler accommodates engine movement under load while maintaining a smooth, tapered transition for maximum air density.
