Cold Air Intake for Toyota 4Runner (1996-1999) 2.7L L4 Engine

Optimize Airflow and Throttle Response for Your 3RZ-FE Toyota 4Runner

Who It’s For: Designed specifically for Toyota 4Runner and Tacoma owners running the 3RZ-FE engine. Whether you are daily driving or hitting the trails, this is for the enthusiast who wants more life out of their four-cylinder workhorse.

The Problem: The stock intake system on the 3RZ-FE is heavily baffled and restricted to reduce engine noise for the average consumer. This creates air turbulence and "chokes" the engine during high-load situations, which is a major drawback for a small displacement engine already tasked with moving a heavy SUV or truck frame.

The Solution: We engineered this intake to eliminate the factory restrictions of the 3RZ-FE, replacing the accordion-style plastic tubing with smooth, mandrel-bent T304 aluminum. This ensures a laminar air flow directly into the throttle body, delivering more oxygen for better combustion and a noticeable improvement in mid-range torque.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Real-world gains of up to 10% in horsepower and torque by reducing pumping losses and improving volumetric efficiency.
• High-Grade Construction: Built with T304 lightweight aluminum piping that resists heat soak better than thinner alloys, ensuring cooler intake charges.
• Serviceable Design: Includes a high-flow, washable cotton-media filter that only requires cleaning every 50,000 miles, making it the last filter you’ll ever buy for this rig.

The Performance Promise

Buy with confidence. As a specialist who has spent years under the hoods of these Toyotas, I can tell you that the 3RZ-FE responds incredibly well to better breathing. This kit includes everything needed for a 60-minute bolt-on installation. We recommend disconnecting the battery during install to allow the ECU to relearn the new fuel trims for the increased airflow. Backed by real automotive experts and fast shipping.
