Cold Air Intake for Lexus IS 250 (2005-2013) 2.5L V6 / IS 350 (2006-2011) 3.5L V6 Engines

Sharpen Throttle Response and Induction Sound for the Lexus GR Series V6

Who It’s For: Designed specifically for Lexus IS owners running the GR Series V6 engine family, including the high-revving 2.5L and the powerhouse 3.5L variants.

The Problem: The GR Series V6 is a masterclass in Toyota engineering, but the factory intake system is heavily baffled to prioritize cabin silence over raw efficiency. Between the restrictive air box and the corrugated plastic intake hose, the engine often feels sluggish off the line, struggling against intake turbulence and heat soak from the engine bay.

The Solution: We engineered this system to replace those factory bottlenecks with a high-velocity T304 aluminum mandrel-bent tube. By straightening the airflow path and utilizing a high-flow washable filter, we allow the GR Series V6 to breathe naturally, improving volumetric efficiency and providing that signature aggressive V6 growl when you bury the pedal.

Why This is the Ultimate Upgrade

• Enhanced Airflow Velocity: By eliminating the factory resonators and accordion-style bellows, this system delivers a more consistent and cooler air charge directly to the throttle body.
• T304 Aluminum Construction: Unlike the stock plastic that becomes brittle and cracks over time due to heat cycles, our lightweight T304 piping is built to handle the thermal demands of a performance sedan.
• True Bolt-On Fitment: Engineered as a direct replacement for the factory setup, meaning you can have this installed and be back on the road in under an hour with standard hand tools.
