- How is air filter quality measured?
- Intake air filters are rated by ISO 5011, which quantifies initial efficiency, dust holding capacity, and restriction (airflow resistance). A quality filter matches OE pleat count and media so it doesn't trade efficiency for airflow; verify the media grammage, a uniform pleat without bunching, and an end-seal gasket that seats fully against the airbox.
