2017-2019 Duramax S&B Cold Air Intake Kit
The S&B Cold Air Intake for the 2017-2019 Silverado / Sierra Duramax 6.6L was engineered to minimize air restriction and flows 47.70% better than stock.
This kit comes with an enclosed airbox that protects the filter from dirt, debris and keeps out engine heat.
This kit comes with a large highly efficient air filter which results in better performance and protects your engine.
On the L5P intake kit, S&B integrated a silicone air scoop that feeds even more air to the filter.
More air equals better performance and the L5P intake kit features two large air inlet points.
If you want to customize the amount of air you take in, S&B includes an optional box plug that can seal off one inlet point.
