K&N 63 Series AirCharger Performance Intake
Maximize the output of your 4.0L V6 with the K&N 63 Series AirCharger. Engineered specifically for the 1GR-FE engine, the 63 Series is the premier choice for enthusiasts seeking the highest possible airflow and raw performance gains. By replacing the restrictive factory air box and baffled intake plumbing with an aerodynamically optimized, high-density polyethylene (HDPE) tube and a massive high-flow filter, this system allows your engine to breathe without restriction, resulting in a guaranteed increase in horsepower.
Performance Engineered for the 4.0L 4Runner
- Significant Power Gains: Dyno-tested to provide a substantial estimated increase of 12.33 HP @ 5270 RPM, giving your 4Runner the extra muscle needed for highway passing, towing, and technical off-road climbs.
- Thermal Isolation: Includes a vehicle-specific heat shield that replaces the stock air box, effectively isolating the filter from engine bay heat to ensure a cooler, denser air charge for better combustion.
- Superior HDPE Construction: The cross-linked polyethylene intake tube is custom-molded to smooth and straighten airflow. Unlike metal alternatives, HDPE resists heat soak, maintaining consistent power delivery even in high-temperature environments.
- Precision Integration: The intake tube is designed to seamlessly accommodate the factory mass air sensor (MAF) and essential vent lines for a secure, factory-quality fit.
Key Features
- Oversized High-Flow Filter: Includes a 6-inch tall, chrome-topped conical filter (RF-1048) that provides superior filtration and can go up to 100,000 miles before its first cleaning (under normal highway conditions).
- Aggressive Intake Tone: Noticeably enhances the sound of your 4.0L engine, providing a deep, performance-oriented growl under acceleration while remaining refined at cruising speeds.
- Simple Installation: Designed to utilize existing factory mounting points-usually completed in 90 minutes or less with basic hand tools like a screwdriver, socket set, and wrenches.
- Million-Mile Protection: Backed by K&N's legendary 1,000,000 Mile Limited Warranty.
