Performance Cold Air Intake System for 2001–2005 Lexus IS300 – 3.0L I6 Airflow & Response

Transform the driving dynamics of your sport sedan with this high-performance cold air intake system, specifically designed for the 3.0L Inline-6 engine. By replacing the restrictive factory intake assembly, this system creates a high-velocity air path that allows your engine to draw in a higher volume of cooler air. The result is sharper throttle response and more robust power delivery across the entire RPM range, perfectly complementing the balanced chassis of the IS300.

Engineered to optimize the performance of the legendary I6 powerplant, this intake supports more efficient combustion by providing the engine with denser, oxygen-rich air. You will notice smoother, more immediate acceleration during spirited drives and a more refined, aggressive engine note that highlights the unique character of the 3.0L engine. This upgrade delivers a performance-oriented sound during acceleration while remaining sophisticated during daily commutes.
