Lexus GS430 Performance Air Intake - Weapon R Secret Weapon (2001-2004). This system lets your 4.3L V8 breathe more freely with a vehicle-specific design and a richer intake note.

Weapon R’s Secret Weapon focuses on efficient airflow and a reusable, high-flow filter. The kit is tailored to the GS430 engine bay for a bolt-on install with included brackets and couplers.
