AirAid 200-285 Cold Air Intake for 2014 Silverado and Sierra 1500 5.3L

All AIRAID Premium Filters use a synthetic filtration media called SynthaFlow. SynthaFlow is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze performance filters can't capture. Based on SAE standards, AIRAID Premium Filters, with SynthaFlow, capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors' filters.
