S&B Filters cold air intake for the 2020-2025 Silverado / Sierra Duramax 6.6L Gas engine was engineered to minimize air restriction and flow better than stock.
This cold air intake kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.
Stock intake boxes are a significant contributor to poor airflow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With that said, S&B recognizes the benefits of cooler air, so we have included a plug to seal off the opening if desired.
