S&B Filters Cold Air Intake for Silverado, Sierra 1500

A cold air intake replaces the factory airbox, tubing and filter. S&B's is a roto-molded enclosed box with silicone seals, so the filter is shut off from hot engine bay air.

why this one — S&B makes no horsepower claim at all. What it publishes instead is measurable: 51.69% more airflow than stock and 99.30 to 99.59% filtration efficiency, which matters if your truck sees dust and gravel roads. If you want a number to brag about, look at Injen or K&N; if you want a sealed box and a filter that actually filters, this is the honest pick at $379, and Sierra fitment is confirmed on S&B's own site.
