Cold Air Intake Kit for 2012-2019 Toyota Tundra 4.6L V8 Gas

The factory intake on your Toyota Tundra 4.6L V8 is built for sound suppression, not airflow. Its restrictive plastic tubing and baffled airbox create turbulence, choking your 1UR-FE engine of throttle response and low-end torque when towing or merging.

The Flashark Cold Air Intake Kit eliminates this bottleneck. Featuring a smooth-walled, mandrel-bent aluminum intake tube and a heavy-duty steel heat shield, it replaces the restrictive factory assembly to draw dense, ambient air from the fender well. This keeps intake charge temperatures 15–25°F cooler than stock.

Engineered to work seamlessly with your factory ECU and MAF sensor, this kit delivers an immediate upgrade in horsepower and throttle response with a rugged V8 growl under heavy acceleration, while remaining drone-free at highway cruising speeds. No tune, no cutting, and no check engine lights.

Installation: 50–75 minutes, basic hand tools, all hardware included.

⚠️ Emissions Notice: Not legal for street use in CA, NY, or other CARB-regulated states. Off-road / competition use only in these jurisdictions. Legal in 49 non-CARB states.
