Product Description

The AEM 21-806C Dryflow Cold Air Intake System is engineered for late-model Lexus GS, IS and RC platforms equipped with the 2.5L or 3.5L naturally aspirated V6 engines. By replacing the restrictive factory airbox with a mandrel-bent aluminum tube, heat shield and oversized Dryflow synthetic filter, this system improves airflow, throttle response and intake sound while maintaining proper integration with factory emissions and sensor hardware.

Developed and dyno-tested specifically for the GS350, IS250, IS350 and RC350 applications listed, the 21-806C is a true vehicle-specific upgrade rather than a universal kit. The oil-free Dryflow media simplifies maintenance and eliminates the risk of MAF contamination from over-oiled filters, while the gunmetal gray finish and clean routing deliver an OEM-plus look in the engine bay. For Lexus owners seeking a refined yet noticeable performance and sound upgrade, this intake provides a balanced solution with proven gains and long-term serviceability.
