Hi-Flow Air Intake System

The STILLEN Hi-Flow Air Intake is a performance-focused replacement for the stock air box on 2003-2008 Infiniti G35 (V35) and Infiniti FX35 (S50) vehicles. The system utilizes smooth-surface tubing and a venturi ring to minimize air turbulence, enhancing overall engine efficiency. As a CARB-exempt component, this kit provides a straightforward, compliant upgrade for owners seeking refined performance without complex modifications. Maintenance is simplified through the use of a reusable, washable filter element. For further performance optimization, this intake can be adapted to the STILLEN Z-Tube (part # 403235) for 2003-2007 Infiniti G35 (V35) models. When combined with the Z-Tube, performance gains can reach approximately 11 WHP on sedan models and 5 WHP on coupe models. Please note that results may vary depending on individual vehicle conditions and configurations.
