STILLEN 2016-2021 Infiniti Q50 / Q60 3.0T Hi-Flow Air Intake - Dry Filter - 402856DF

Unleash massive torque and sharper throttle response from your 2016–2021 Infiniti Q50 or Q60 3.0T with the STILLEN Hi-Flow Air Intake System w/ Dry Filters. Designed, engineered, and manufactured in-house at STILLEN (USA), this intake delivers real-world, dyno-proven gains while maintaining OEM reliability and drivability—no tune required and no check engine lights.

The factory intake system on Infiniti’s twin-turbo 3.0T engine is heavily restricted to prioritize quiet operation. STILLEN replaces those restrictions with high-flow polyurethane air ducts, custom heat shields, and large surface-area washable dry filters, creating a true cold air intake system that feeds your turbos cooler, denser air for maximum performance.

Tested on a Q50 Silver Sport, this intake delivers up to 17 WHP and 28 WTQ, with peak gains occurring right where you feel them most—around 3,200 RPM. The result is a dramatic increase in midrange torque that pushes you back into the seat, along with a deeper, more aggressive turbo induction sound.

Overview

The STILLEN Hi-Flow Intake for Infiniti 3.0T engines was engineered specifically for turbocharged applications where incoming air temperature directly impacts power output. Unlike exposed “warm air” intakes, this system fully shields the filters from engine bay heat and draws cooler air through custom-molded polyurethane ducts.

Cooler air entering the turbos means the intercooler has less heat to remove, resulting in a denser, oxygen-rich air charge—and more power. This is why the car feels strongest in cool “boost weather,” and why proper intake heat shielding matters even on intercooled turbo vehicles.

Beyond the performance gains, the intake transforms the driving experience. Under throttle, you’ll hear a deep, authoritative induction note as the turbos inhale massive volumes of air. On lift-off, the airflow produces a satisfying turbo sound reminiscent of a blow-off effect—without any obnoxious drone during normal driving.

As with all STILLEN intakes, this system is engineered for safe, reliable power on the factory ECU, preserving proper air-fuel ratios and drivability while delivering real performance gains and a clean, aggressive underhood look.
