K&N 57 Series FIPK Performance Air Intake | 2000-2004 Tacoma & 4Runner

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 4.7L 2UZ-FE engine, the factory intake assembly is a primary source of air restriction. This system replaces the restrictive stock housing and filter with an aerodynamically engineered, high-density polyethylene (HDPE) intake tube and an oversized high-flow filter. By straightening the air 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 responses.

Performance Engineering for the 4.7L V8

• Measured Power Gains: Dyno-tested to provide a substantial estimated increase of 6.19 HP @ 4200 RPM, delivering improved pulling power exactly where you need it for towing or highway passing.
• Thermal Isolation: Includes a vehicle-specific 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 in high-temperature environments.
• Full Component Integration: The precision-molded tube is designed to accommodate the factory mass air sensor (MAF) and includes a replacement silicone fuel pressure regulator line for a secure, long-lasting fit.

Key Features

• Washable Lifetime Filter: Includes a chrome-topped, oversized conical filter (RF-1037) that can go up to 100,000 miles before its first cleaning is required (under normal highway driving conditions).
• Aggressive V8 Tone: Enhances the 4.7L engine's intake sound, providing a deep performance-oriented growl under acceleration while maintaining a refined cabin experience 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.
