K&N drop-in high-flow air filter for the 2008–2011 Lexus IS F 5.0L V8 is a washable, reusable replacement designed to improve airflow and help increase horsepower. The layered, oiled cotton media captures contaminants while allowing higher flow, and the filter installs into the factory airbox for a simple swap. K&N backs the product with its long-term limited warranty.
