High-performance engines have enormous airflow needs, and racers are constantly looking for a little something extra that will give them an edge over the competition. AIRAID Track Day Filters feature the same quality construction as AIRAID premium air filters, including sturdy polyurethane casings, wire mesh construction, and layers of high flow cotton gauze. They are designed to provide restriction-free airflow while still maintaining adequate filtration. Track Day Filters are shipped dry but can be oiled if desired. Track Day air filters are backed by a 90-day warranty. These filters are not intended for street use and are not recommended for any off-the-shelf cold air intake system that will be used in anything other than a controlled racing environment.
