Description

The STILLEN Hi-Flow Air Intake is a performance-oriented cold air intake engineered to replace the restrictive factory airboxes on the 2016-2024 Infiniti Q50 and Q60 3.0t. By removing intake silencers and optimizing airflow, this system provides increased power and torque without requiring an ECU tune or triggering a check engine light. The kit includes custom-molded urethane heat shields and air ducts, which ensure that the engine draws in cooler, denser air compared to unshielded filter setups. This intake does not alter, remove, or modify any OEM emissions control equipment. Please note that this product is not for sale in California. Ensure your vehicle falls within the 2016-2024 production range for the Infiniti Q50 or Q60 with the 3.0t engine for correct compatibility.
