Cold Air Intake for Lexus IS300 (2001-2005) 3.0L Inline-6 Engine

Improve Throttle Response & Induction Sound for Your Lexus IS300 2JZ-GE

Who It’s For: Designed specifically for 2001–2005 Lexus IS300 owners running the legendary 2JZ-GE engine family. Whether you are daily driving an automatic sedan or rowing gears in a rare manual SportCross, this is the first step in making the inline-six breathe correctly.

The Problem: The 2JZ-GE is a masterpiece of engineering, but the factory air box is a massive, multi-chambered plastic unit designed for maximum silence, not maximum flow. This restrictive setup creates a bottleneck, especially as the VVT-i (Variable Valve Timing) tries to optimize performance at higher RPMs. Furthermore, after two decades, the factory rubber accordion hoses are prone to cracking and vacuum leaks.

The Solution: We engineered this intake to replace the baffled factory unit with a mandrel-bent T304 aluminum pipe. This smooths out the intake path and allows the 2JZ-GE to draw in a higher volume of oxygen-rich air, resulting in a noticeable improvement in mid-range torque and a crisp, metallic induction note that every straight-six enthusiast craves.

Why This is the Ultimate Upgrade

• Enhanced Airflow: By eliminating the factory baffles and restrictive paper filter, this system supports up to 10% gains in horsepower and torque under optimal driving conditions.
• Built for Longevity: Constructed from T304 lightweight aluminum, this piping resists the high under-hood temperatures that typically cause factory plastic components to degrade and brittle over time.
• Maintenance-Free Filtration: Features a washable and reusable high-flow air filter that only requires servicing every 50,000 miles, saving you money on disposable filters for the life of the vehicle.

The Performance Promise

Buy with confidence. As specialists in the XE10 chassis, we know that fitment is everything. This kit is designed for a direct bolt-on experience using standard hand tools in under 60 minutes. We recommend disconnecting the battery for 10 minutes after installation to allow the ECU to reset its long-term fuel trims and adapt to the increased airflow.
