Toyota Tundra 2nd Gen 2012-2021, K&N NextGen Cold Air Intake System

A Tundra 5.7L V8 on a long grade with a trailer behind it moves a lot of air through the factory intake, and the stock air box and inlet limit how much reaches the engine.

The K&N NextGen system uses a large-diameter roto-molded tube with air channels, a hybrid semi-enclosed airbox that helps lower air temperatures, and an oversized filter with a radius-entry design. K&N lists an increase in airflow of 60.4% and estimated gains of 14.2 HP and 35.3 lb-ft.

Quick-Lock technology snaps the filter into place, and a sealing bead secures the system with one hose clamp.
