Cold Air Intake Kit for 1999–2004 Toyota Tacoma 3.4L V6 (5VZ-FE Engine)

Toyota Tacoma (3.4L V6) Airflow Efficiency & Added Torque

Maximize the output of your Tacoma's legendary 5VZ-FE engine with this high-velocity air induction system, specifically engineered for the 3.4L V6 platform. By replacing the restrictive factory air box with a streamlined intake path and an integrated heat barrier, this kit allows your engine to draw in a larger volume of oxygen-rich air while effectively blocking engine bay heat. The result is a more energetic combustion cycle, providing crisper throttle sensitivity and more fluid acceleration whether you are navigating technical trails or cruising the highway.

This system provides a substantial mechanical upgrade that modernizes your engine bay. By maximizing airflow efficiency and maintaining lower intake temperatures, this kit enhances horsepower and torque, giving your Toyota the extra surge needed for towing, hauling, and off-road maneuvers. Beyond the mechanical gains, it grants your V6 a deeper, more authoritative growl under load, perfectly matching the rugged and capable character of the first-generation Tacoma.

About Your 1999-2004 Toyota Tacoma 3.4L V6

The first-generation Toyota Tacoma (1999-2004) with the 3.4L V6 5VZ-FE engine is renowned for its bulletproof reliability and legendary durability. This workhorse engine delivers dependable performance, but the factory air intake system prioritizes noise reduction and cost efficiency over maximum power output.

Easy Installation

Tools Required: Basic hand tools (wrenches, screwdrivers, pliers)

Installation Steps

1. Disconnect the NEGATIVE battery cable before starting installation
2. Remove the factory air box and intake tube
3. Install the heat shield using provided hardware
4. Mount the intake pipe and secure all connections
5. Attach the performance air filter
6. Double-check all clamps and connections

Installation Tip: Disconnect the NEGATIVE GROUND CABLE from the battery before starting the installation. This allows the engine's computer to reset and calibrate for the increased airflow and cooler intake temperatures. Always ensure the engine is completely cool before beginning work.

Why Upgrade from Factory?

The factory air intake system on your Tacoma prioritizes cost reduction and noise suppression over performance. The restrictive air box and intake tube limit airflow to your engine, leaving power on the table.

Factory Intake Limitations

• Narrow intake tubing creates turbulence and restriction
• Paper air filter requires frequent replacement
• Multiple bends and turns reduce airflow efficiency
• Heat from engine bay warms incoming air, reducing power and efficiency
• Designed for noise reduction and cost savings, not performance

Our cold air intake system addresses all these issues, delivering cooler, denser air to your 5VZ-FE engine for measurable performance gains you can feel every time you drive. With an estimated 15-19 additional horsepower and 18-22 lb-ft of extra torque, your Tacoma will reach approximately 205-209 HP and 238-242 lb-ft of torque with this upgrade.
