STILLEN 2018-2023 Kia Stinger AWD/RWD [3.3TT] Hi-Flow Air Intake Kit w/ Oil Filter - 402883

The STILLEN Hi-Flow Air Intake Kit for 2018–2023 Kia Stinger AWD/RWD 3.3L Twin-Turbo [402883] is a precision-engineered solution designed to maximize engine airflow, throttle response, and horsepower. Featuring mandrel-bent aluminum intake tubes and an enclosed urethane airbox, this kit replaces the restrictive factory intake system, including the stock air filter and housing. The included Genuine K&N oiled filter provides up to 50% more airflow, protecting your engine while increasing performance.

Extensive testing and engineering went into creating a smooth airflow path from the filter to the turbine housings. Polyurethane heat shields block hot engine bay air, ensuring cooler intake temperatures for more efficient combustion. Dyno testing shows gains of +25 HP @ 5000 RPM and +31 lb-ft of torque @ 3800 RPM at the wheels, with improved throttle response and efficiency across the power band. This kit is designed for easy installation in your driveway or garage, without cutting or modification.

STILLEN also tested this intake for over 5,000 miles to ensure durability and reliability under real-world conditions. Drivers reported improvements in long-distance fuel economy and responsiveness, with a more aggressive turbo sound when the system is under boost.
