STILLEN 2014-2015 Infiniti Q50 Gen 2 Air Intake Kit [V37] - Dry Filter - 403230DF

Upgrade the performance, throttle response, and engine bay appearance of your 2014–2015 Infiniti Q50 (V37) with the STILLEN Gen 2 Air Intake System w/ Dry Filters. Designed and manufactured in-house in the USA, this intake replaces the restrictive factory airboxes with a true cold air intake system engineered to deliver consistent power gains while maintaining OEM drivability—no tune required and no check engine lights.

The STILLEN Gen 2 intake features twin mandrel-bent polished aluminum intake tubes, polyurethane heat shields, and high-flow washable dry air filters with a larger surface area than stock. This combination significantly improves airflow and filtration efficiency, resulting in sharper throttle response, increased horsepower, and potential improvements in fuel economy.

Unlike exposed filter setups that pull in hot underhood air, STILLEN’s polyurethane heat shields isolate the filters from engine bay heat, ensuring cooler, denser air is delivered to the engine. The result is more consistent performance across the rev range and a more aggressive, performance-oriented induction sound under throttle.
