CORSA Performance Closed Box Air Intake

A cold air intake replaces the factory airbox, tubing and filter with a less restrictive setup. CORSA's is a closed-box design, meaning the filter stays sealed inside its own housing instead of sitting open to hot engine bay air.

why this one — CORSA claims +11 hp and +11 lb-ft and, unusually, says right on its own page that results are not guaranteed and may vary, with no dyno method published. It is the clearest of the bunch on fitment though, stating outright that it fits the 2019 new body only and not the 2019 Silverado 1500 LD carryover. Heads up: CORSA's own listing says 2019-2025 while this entry reads 2019-2026, so confirm before buying for a 2026.
