Cold Air Intake for Toyota 4Runner (1996-1999) Tacoma (1995-1999) 2.7L Engine

Maximize Airflow and Throttle Response for your Toyota 3RZ-FE Engine

Who It’s For: Designed specifically for Toyota 4Runner and Tacoma owners running the 3RZ-FE 2.7L inline-four engine who want to wake up their truck’s performance during daily hauls or off-road excursions.

The Problem: The factory airbox on the 3RZ-FE is a maze of restrictive plastic baffles and corrugated tubing. This setup is designed for sound suppression rather than efficiency, which often leaves the engine feeling sluggish under load and creates a noticeable delay in throttle response.

The Solution: We engineered this intake system to replace that restrictive factory plumbing with smooth, mandrel-bent T304 aluminum. By providing a direct, high-velocity path to the throttle body, we eliminate the turbulence that plagues the stock 3RZ-FE, resulting in a cleaner power band and a much more responsive pedal feel.

Why This is the Ultimate Upgrade

• Proven Power Gains: Dyno-consistent gains of 7–10% Horsepower and 6–8% Torque by reducing intake pumping losses.
• T304 Aluminum Construction: Unlike plastic that can crack or heat-soak, our lightweight aluminum piping dissipates heat faster and provides a permanent, durable solution for the engine bay.
• Maintenance-Free Filtration: Includes a high-flow, washable pleated filter that provides superior filtration while allowing for significantly more CFM than paper filters.

The Performance Promise

Expert Tip: After you finish the install, disconnect your negative battery terminal for about 10 minutes. This resets the Long Term Fuel Trims (LTFT) in your ECU, allowing it to "re-learn" the new airflow parameters immediately rather than over several drive cycles. You’ll feel the difference on the very first pull. Buy with confidence from a team that knows Toyotas inside and out.
