The K&N 33-3009 air filter is a high-flow air filter for the Kia Rio, designed as a direct replacement for the factory air filter. It is reusable, pre-oiled, and made from four layers of oil-impregnated cotton material bonded with a special adhesive. The layers trap dust, dirt, and contaminants, while its design improves airflow.
Under normal highway driving conditions, it needs cleaning every 75,000 km or every 5 years. It can be installed in minutes without tools.
