Black Cold Air Intake Kit for Toyota 4Runner (1999-2002) with 3.4L V6 Engine Pro

Increased Throttle Response for 1999-2002 Toyota 4Runner 3.4L V6 5VZ-FE

Who Is This For? Designed specifically for 3rd Gen Toyota 4Runner owners running the 5VZ-FE engine who need more consistent power for daily driving, highway passing, and weekend off-road adventures.

The Factory Air Box Restriction: From the factory, your 4Runner’s 3.4L V6 is choked by a restrictive plastic air box and corrugated rubber tubing that creates massive turbulence. You step on the gas to merge or climb a grade, and the engine feels bogged down, struggling to pull air through the heat-soaked engine bay. This lack of airflow directly translates to sluggish throttle response and wasted fuel efficiency.

The Engineering Solution: We engineered this Black Cold Air Intake Kit to provide a high-velocity, low-turbulence path for oxygen to reach the intake manifold. By replacing the accordion-style factory hose with mandrel-bent aluminum piping and adding a dedicated heat shield, we ensure the 5VZ-FE draws in cooler, denser air. The result is a more efficient combustion cycle that delivers a noticeable growl under load and a sharper response every time you tip into the throttle.

The Comparative Edge: Why This Beats the Competition

• The Pro Red Advantage: Features a high-flow Pro Red reusable filter that offers superior surface area compared to restrictive paper filters or generic thin-foam alternatives that let fine dust into your engine.
• Mandrel-Bent Aluminum: Constructed from durable, lightweight aluminum finished in a sleek black coating. Unlike cheap plastic intakes that can crack over time or generic kits with corrugated "flex" hoses that cause air turbulence, our smooth-wall design maximizes air velocity.
• Direct High-Mileage Refresh: Designed as a direct bolt-on using factory mounting locations. This kit is the perfect way to restore performance to a high-mileage 5VZ-FE by removing decades of carbon-clogged factory components.
