A cold air intake replaces the factory airbox and filter with a larger, less restrictive filter inside a sealed housing, so the turbo draws air more freely and you hear more of it.
why this one — S&B is the pick here if you care about filtration as much as flow, because they publish both numbers for this exact kit rather than just the flashy one: 53.06 percent more airflow and 99.27 percent filtration efficiency. It also carries CARB Exempt ID D-590-15, so it stays street legal in all 50 states, which not every intake on this truck can say. The honest tradeoff is that no horsepower figure is published, and on a stock-tuned diesel an intake mostly buys you sound and airflow headroom for later rather than a number today.
S&B publishes 53.06% increased airflow and 99.27% filtration efficiency for this kit, and CARB Exempt ID D-590-15, but publishes no hp or torque figure. Not invented here. source ↗
