K&N 63 Series AirCharger Performance Intake
Maximize the output of your i-Force V8 with the K&N 63 Series AirCharger. Engineered specifically for the early 4th Gen 4Runner, the 63 Series is the premier choice for enthusiasts seeking maximum airflow and high-end performance gains. By replacing the entire restrictive factory air box and baffled intake plumbing with am aerodynamically optimized, high-density polyethylene (HDPE) tube and a massive high-flow filter, this system allows your 3UZ-FE engine to breathe without restriction, resulting in a guaranteed increase in horsepower.
Performance Engineering for the 4.7L V8
- Measured Power Gains: Dyno-tested to provide a substantial estimated increase of 9.23 HP @ 5388 RPM, giving your 4Runner the extra muscle needed for highway passing and steep off-road climbs.
- Thermal Isolation: Includes a specialized heat shield that mounts directly to the inner fender, effectively isolating the filter from engine bay heat and ensuring 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.
- Direct-to-Throttle-Path: The aerodynamically engineered tube directs air past the mass air sensor and straight into the throttle body eliminating the turbulence caused by factory accordion hoses.
Key Features
- Oversized High-Flow Filter: Includes a 7-inch tall, chrome-topped conical filter (RC-5100) that provides superior filtration and can go up to 100,000 miles before its first cleaning (under normal highway conditions).
- Deep V8 Intake Tone: Noticeably enhances the sound of your 4.7L engine, providing a deep aggressive growl under acceleration.
- Simple Installation: Designed to utilize the existing factory mounting points-usually completed in 90 minutes or less with basic hand tools like pliers, a screwdriver, and a socket set.
- Million-Mile Protection: Backed by K&N's legendary 1,000,000 Mile Limited Warranty.
