Product Description

The K&N 69-5321TS Typhoon Cold Air Intake System is engineered for 2015-2019 Hyundai Sonata and 2015-2020 Kia Optima models equipped with the 2.4 L L4 engine in front-wheel drive configuration. By replacing the factory air intake system with a smoother, larger diameter aluminum tube and high-flow cotton gauze filter, this performance system reduces intake restriction and increases airflow into the engine - leading to enhanced acceleration and throttle response along with a modest gain in horsepower and torque.

Installation is designed to be straightforward, requiring basic hand tools and typically completed in around 90 minutes or less. Because the air filter is washable and reusable, service intervals are significantly extended. Do note that this kit is *not* listed as CARB-legal for California (or states adopting California's standards) unless explicitly marked, so check local emissions regulations if applicable.

Backed by K&N's No-Hassle Lifetime Limited Warranty, this intake system represents a reliable performance upgrade for enthusiasts seeking improved responsiveness and airflow in the Sonata/Optima 2.4 L models.
