The K&N Typhoon cold air intake for 2019–2020 Mazda 3 2.5L employs a mandrel-bent aluminum tube with a washable, reusable high-flow cotton filter to increase horsepower and torque while improving intake airflow. The system is installed using common tools and is backed by K&N's No-Hassle Lifetime Limited Warranty; K&N notes these systems are engineered to avoid voiding the vehicle warranty under normal conditions.
