Weapon R 2000-05 Lexus IS300 3.0L V6 Stealth Secret Weapon Intake Flat Black

Weapon R Stealth Secret Weapon Intake (Flat Black) for 2001–2005 Lexus IS300 3.0L V6

Transform the performance and appearance of your 2001–2005 Lexus IS300 with the Weapon R Stealth Secret Weapon Intake in Flat Black. Featuring patented dual-velocity technology, this intake creates two separate air streams one traveling at high speed and one at lower speed to deliver up to **3 times more air** to the engine than the stock system. The result is improved throttle response, stronger mid-range power, and a deeper, more aggressive intake sound. Finished in a stealthy flat black, it gives your IS300 a subtle, aggressive look while maintaining the high-quality construction Weapon R is known for.
