K&N Stock Air Filter Replacement for C5 and Z06 Corvette

Replace your stock element filter with this K&N filter for the C5 and Z06 Corvette and increase horsepower. Non-restricting means dust and dirt will not clog the filter element as quickly as paper or foam because foreign matter remains on the outside of the element. Free-flowing, even with an outer layer of dust and dirt there is adequate airflow.
