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.

Key Features

• High-Flow Aluminum Tube — Mandrel-bent 6061 aluminum maintains a uniform diameter to eliminate air turbulence and optimize airflow to the throttle body.

• XL Conical Dry Filter — Washable, reusable, and oil-free; provides maximum surface area for clean, sustained airflow without risking MAF sensor fouling.

• Sealed Heat Shield — Heavy-duty steel construction with weather stripping seals tightly against the hood to block hot engine bay air.

• Factory-Calibrated Fit — Precision MAF section guarantees clean air-fuel readings; 100% compatible with stock Toyota ECU without throwing a CEL.

• Direct Bolt-On — Uses factory mounting points; no drilling, welding, or cutting required for a quick, straightforward garage installation.

• Aggressive V8 Sound — Delivers a deep, throaty rumble under throttle while maintaining comfortable cab volume during daily driving.
