K&N 57 Series FIPK Performance Air Intake
Maximize the output of your i-Force V8 with the K&N 57 Series FIPK (Fuel Injection Performance Kit). For the early 4.7L 2UZ-FE, the factory air box and restrictive intake plumbing act as a significant bottleneck. This system replaces the entire factory assembly with an aerodynamically engineered, high-density polyethylene (HDPE) intake tube and an oversized high-flow filter. By smoothing the airflow path and reducing intake temperatures, your engine can inhale a larger volume of oxygen-rich air, resulting in a guaranteed increase in horsepower and significantly sharper throttle response.
Performance Engineering for the 4.7L V8
- Measured Power Gains: Dyno-tested to provide a substantial estimated increase of 9.45 HP @ 4842 RPM, giving your Tundra the extra muscle needed for highway passing and heavy towing.
- Thermal Isolation: Includes a specialized heat shield that replaces the factory air box, isolating the filter from engine bay heat to ensure a cooler, denser air charge for better combustion.
- Rotomolded HDPE Intake Tube: The cross-linked polyethylene intake tube is designed to eliminate internal turbulence and resists heat soak more effectively than metal tubes, maintaining consistent power under load.
- Seamless Integration: The precision-molded tube is designed to accommodate the factory mass air sensor (MAF) and vent lines ensuring a factory-quality fit and "no code" operation.
Key Features
- Washable Lifetime Filter: Includes a chrome-topped oversized conical filter that can go up to 100,000 miles before its first cleaning (under normal highway driving conditions).
- Aggressive V8 Growl: Enhances the 4.7L engine's intake sound, providing a deep, performance-oriented growl under acceleration without being overbearing at cruising speeds.
- Easy Bolt-On Install: Designed to mount to existing factory points-usually completed in 90 minutes or less with basic hand tools.
- 50-State Street Legal: Fully CARB-compliant (EO-Number: D-269-28) and street legal in all 50 US states.
