Cold Air Intake W/Heat Shield For Toyota Tacoma/ 4 Runner (1999-2004) with 3.4L V6 Engine Black

Boost your 5VZ-FE's performance with this complete cold air intake kit—engineered for the legendary 3.4L V6 that owners routinely drive past 200,000 miles with minimal issues.

More Power from Toyota's Bulletproof 3.4L V6

The 1999-2004 Tacoma and 4Runner equipped with the 5VZ-FE 3.4L V6 represents the sweet spot of Toyota's truck lineup—183 horsepower, 217 lb-ft of torque, and legendary reliability that enthusiasts describe as "bulletproof." Owners routinely report these engines running well beyond 200,000 miles with minimal issues when properly maintained, and forum discussions consistently praise the 5VZ-FE as "a 24 valve 4 cam masterpiece" that defined Toyota's reputation for dependability. The DOHC design with four valves per cylinder was tuned specifically for low-end torque—perfect for off-roading and towing—but Toyota prioritized silence and emissions compliance over maximum airflow when designing the restrictive factory intake system.

This cold air intake addresses that restriction by replacing your stock air filter box and intake tube with T304 aluminum piping and a high-flow washable filter with integrated heat shield. The result is up to 10% gains in horsepower and torque—measurable improvements in throttle response and mid-range pulling power that complement the 5VZ-FE's already strong low-rpm torque curve. The heat shield keeps intake air temperatures down by isolating the filter from radiant engine heat, ensuring cooler, denser air reaches your throttle body. You'll also get that deeper V6 intake tone that adds character without excessive noise. The washable filter requires service only every 50,000 miles, and installation takes under an hour with basic hand tools.

Key Features at a Glance

• Up to 10% Power Gains: Improved airflow delivers noticeable horsepower and torque increases with sharper throttle response throughout the RPM range
• T304 Aluminum Construction: Lightweight, corrosion-resistant piping withstands engine bay heat while reducing weight compared to factory plastic components
• Integrated Heat Shield: Isolates the air filter from engine bay heat, delivering cooler, denser intake air for better combustion efficiency
• Washable, Reusable Filter: High-flow synthetic media requires cleaning only every 50,000 miles under normal driving conditions—long-term savings over disposable filters
• Enhanced V6 Sound: Deeper intake tone adds character under acceleration—complements the 5VZ-FE's smooth powerband

How It's Used: Installation & Fitment

Installation involves removing your factory airbox assembly and replacing it with the new high-flow intake system. Disconnect the intake tube from the throttle body, unbolt the airbox from its mounting points in the engine bay, and remove the complete assembly. The new T304 aluminum piping connects to the throttle body using the provided clamps, with the high-flow filter mounting in a location protected by the integrated heat shield. The kit includes all necessary mounting hardware and clamps. Most installations take 45-60 minutes using basic hand tools—screwdrivers, socket wrenches, and pliers for the hose clamps. After installation, disconnect the battery terminal for 10-15 seconds to reset the ECU, allowing it to adapt to the increased airflow and optimize performance.

Product Durability & Material Details

The T304 aluminum intake piping is chosen for its corrosion resistance and thermal properties—critical for vehicles that see off-road use and harsh environments. The high-flow air filter uses advanced synthetic media that flows significantly more air than the factory paper element while maintaining proper filtration to protect your engine. The integrated heat shield creates a barrier between the filter and radiant engine heat, ensuring intake air stays as cool as possible for maximum power. Cooler air is denser, which means better combustion efficiency. The washable filter design eliminates recurring replacement costs—simply remove it every 50,000 miles, wash with soap and water, dry completely, and reinstall. No oiling required, which eliminates any risk of contaminating your mass airflow sensor.
