K&N 77 Series High-Flow Performance Intake | 2000-2004 Tacoma & 4Runner

K&N 77 Series High-Flow Performance Intake

Elevate the performance and engine bay aesthetics of your early first-generation Tacoma with the K&N 77 Series High-Flow Performance Intake. Engineered specifically for the 3.4L 5VZ-FE, the 77-9016KP replaces the restrictive factory air box and rubber intake plumbing with a premium mandrel-bent aluminum induction path. By smoothing and straightening the airflow, this system allows your engine to inhale a larger volume of oxygen-rich air, resulting in a guaranteed increase in horsepower and significantly sharper throttle response. 

Performance Engineering for the 3.4L V6

• Mandrel-Bent Aluminum Tubing: Features a high-quality aluminum intake tube that is mandrel-bent to maintain a constant diameter. This eliminates power-robbing turbulence found in factory corrugated hoses, ensuring air moves efficiently to the throttle body.
• Premium Polished Finish: The 77 Series is designed for enthusiasts who value form as much as function. The tube features a high-luster, chrome-like finish that provides a "show-car" look while resisting corrosion over time.
• Thermal Protection: Includes a custom-fit heat shield that installs  into the original air box space, effectively blocking radiant engine heat to ensure your Tacoma pulls the coolest, densest air charge possible.
• Comprehensive Integration: The intake tube is precision-machined to accommodate the factory mass air sensor (MAF), idle air vent line (where equipped), and includes replacement silicone lines for the fuel pressure regulator and EVAP canister.

Key Features

• Measured Power Gains: Dyno-tested to provide a substantial estimated increase of 5.41 HP @ 4365 RPM, delivering improved torque for highway merging and off-road technical sections. 
• Washable High-Flow Filter: Equipped with an oversized, chrome-topped conical filter (RF-1037) that can go up to 100,000 miles before its first cleaning (under normal driving conditions).
• Aggressive Engine Tone: Enhances the natural sound of the 3.4L V6, giving it a deep, performance-oriented grow under acceleration while remaining refined at cruising speeds.
• Simple Installation: Designed to mount directly to existing factory points-usually completed in 90 minutes or less with basic hand tools like a screwdriver, ratchet set, and wrenches.
• 50-State Street Legal: This system is carb-exempt (EO Number: D-269-31) and legal for highway use in all 50 US states.
