K&N 77 Series High-Flow Performance Intake
Upgrade the performance and under-hood aesthetics of your Toyota FJ Cruiser with the K&N 77 Series High-Flow Performance Intake. Engineered specifically for the 4.0L 1GR-FE, the 77-9030 KP replaces the restrictive factory air box and baffled rubber intake hose with a premium mandrel-bent aluminum induction path. By smoothing the airflow and increasing the volume of oxygen-rich air reaching the engine, this system delivers a guaranteed increase in horsepower and significantly sharper throttle response-ideal for both highway cruising and technical off-road trails.
Performance Engineering for the FJ Cruiser
- Mandrel-Bent Aluminum Tubing: Unlike factory plastic components, this high-quality aluminum tube maintains a constant diameter through every bend. This reduces power-robbing turbulence and ensures a high-velocity air charge reaches the throttle body.
- Premium Polished Finish: The 77 Series is the premier choice for owners who value aesthetics, featuring a high-luster finish that provides a custom "show-car" look while resisting corrosion in harsh engine bay environments.
- Thermal Isolation: Includes a vehicle-specific heat shield designed to isolate the air filter from radiant engine bay heat, ensuring your V6 pulls the coolest, densest air possible for optimal combustion.
- Full Component Integration: The intake tube is precision-machined to accommodate the factory mass air sensor (MAF) and crankcase vent hose, and includes a replacement silicone fuel pressure regulator hose for a secure, factory-style fit.
Key Features
- Measured Power Gains: Dyno-tested to provide a substantial estimated increase of 8.17 HP @ 4785 RPM, delivering the extra torque needed to move an FJ Cruiser equipped with heavy armor, winches and oversized tires.
- Washable High-Flow Filter: Features an oversized, chrome-topped conical filter (RF-1048) that provides superior engine protection and can go up to 100,000 miles before its cleaning (under normal driving conditions).
- Aggressive Intake Tone: Noticeably improves the sound of your FJ, delivering a deep, performance-oriented growl under acceleration while remaining refined at cruising speeds.
- Simple Installation: Precision-engineered to utilize existing factory mounting points-installation is typically completed in 90 minutes or less with basic hand tools.
- Million-Mile Protection: Backed by K&N's legendary 1,000,000 Mile Limited Warranty.
