Toyota 4Runner (3.4L V6) Thermal-Shielded Cold Air Induction System

Unleash the Full Potential of Your Legendary 5VZ-FE Engine

The third-generation 4Runner built its reputation on legendary reliability and unstoppable off-road capability. Now it's time to give your 3.4L V6 the performance upgrade it deserves. This thermal-shielded cold air induction system transforms your engine's breathing, replacing the restrictive factory airbox with a precision-engineered intake path that delivers maximum airflow exactly when you need it most.

Picture this: you're approaching a steep trail entrance with gear loaded, or merging onto the highway with the family aboard. With this cold air intake installed, your 4Runner responds with immediate, confident power. The integrated heat shield actively blocks scorching engine bay temperatures, ensuring your V6 breathes only dense, oxygen-rich air for optimal combustion. The result? Noticeably sharper throttle response, improved torque delivery for towing and hauling, and that signature aggressive growl that perfectly matches your truck's rugged character.

Why This System Transforms Your Driving Experience

Your 4Runner was built to go anywhere—this intake system ensures it gets there with authority. By maximizing airflow efficiency and maintaining consistently cool intake temperatures, you'll experience measurable gains in both horsepower and torque across the entire RPM range. Whether you're crawling over boulders at low speed or passing on two-lane highways, the enhanced air-to-fuel ratio delivers the power surge you've been missing.
