Hi-Flow Cold Air Intake System

The STILLEN Hi-Flow Air Intake is a performance cold air intake system engineered to replace restrictive factory airboxes on 2016-2024 Infiniti Q50 and Q60 3.0L twin-turbo vehicles. By removing intake silencers and optimizing airflow paths, this system provides a measurable increase in power and improved throttle response without the need for an aftermarket ECU tune. Constructed with custom-molded polyurethane air ducts and heat shields, this intake system ensures incoming air remains cooler and denser than setups that leave filters exposed under the hood. The system includes a washable, pre-oiled high-flow filter, which maintains filtration efficiency while keeping the turbos well-fed with air. The design is intended to work safely with the factory ECU, ensuring no check engine lights. Please note that for the 2016 Infiniti Q50 specifically, this system carries CARB E.O. #D-436-22 status. While compatible with the specified Q50 and Q60 3.0T engines, proper installation requires care, particularly regarding the positioning of silicon boots and air ducts to ensure the heat shields align correctly and the air intake path remains unobstructed.
