Weapon-R Stealth Black Secret Weapon Intake Kit Lexus IS300 3.0L V6 2000-2005 for 2001-2005 Lexus IS300 305-123-109 | Vivid Racing
If you're looking to give your Lexus IS300 a little extra kick, the Stealth Black Intake is where it's at. This isn't just any intake; it's designed to amp up the air volume reaching your engine. By creating two different air velocity profiles, it gets that precious air flowing in at different speeds, which means your engine gets fed about three times more air than with a standard intake. Yeah, you read that right—three times!
The intake pipe is crafted from top-notch 6061 aluminum, bent using Weapon-R's Automated CNC mandrel bender, which means it’s not just strong but looks slick too, thanks to its polished finish. And let’s talk about the SW1 Air filter—it’s got a tuned velocity stack that helps boost air speed while cutting down on turbulence. It’s all about getting that smooth airflow to your engine.
Plus, this beauty comes with a million-mile limited warranty. That’s right, a million miles! The open pore high-density reusable foam filter is not just durable; it’s also designed to last, so you won't be swapping it out every few months. And with over 250 applications across cars, trucks, and SUVs, it’s a versatile option (USA PATENT # 7,263,961B2).
