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

Performance Cold Air Intake Kit

Fits 2001–2005 Lexus IS300 3.0L Inline-6 (2JZ-GE)

Enhance the performance and sound of your Lexus IS300 with this high-flow cold air intake system, designed to replace the restrictive factory air box and intake tube. Built specifically for the legendary 3.0L Inline-6 2JZ-GE engine, this intake improves airflow efficiency, throttle response, and overall driving excitement—while maintaining daily-driver reliability.

By allowing your engine to draw in cooler, denser air, the intake helps improve combustion efficiency, delivering stronger acceleration, smoother power delivery, and a deeper, sportier intake tone under throttle.
