K&N 2014+ Stingray Replacement Filter

K&N high-flow replacement air filters are made with cotton instead of paper. K&N’s high-flow cotton gauze air filters provide less restriction than typical paper air filters, which can increase the efficiency of the combustion process. Allowing your engine to breathe easier can give your car extra horsepower and extra acceleration that can come in handy, even during every day driving. Performance filter E-0665 is designed as an air filter cross reference to the stock paper filter which makes a K&N replacement air filter an easy to install performance upgrade.

Some might be worried that an increase in airflow comes at the expense of filtration efficiency and engine protection. K&N performs filtration efficiency testing following the internationally recognized ISO 5011 protocol to guarantee that our air filters will provide high airflow without sacrificing engine protection. When tested using ISO Coarse test dust, part number E-0665, for the 2014 and 2015 Corvette was shown to have a 98.46% overall efficiency rating. Calling this test dust coarse is almost preposterous, as 22% of the dust is rated at 10 microns or less. To provide perspective, a human blood cell is typically between 6 and 8 microns across.
