Universal Air Filter 4 in X 2 in Paper is a conventional dry replacement air filter for air-cleaner assemblies matching the listed dimensions. It provides a simple, no-maintenance filtration option for carbureted, throttle-body-injected and custom air-cleaner setups where a disposable element is preferred.
This style uses paper filter media rather than Spectre’s washable HPR synthetic media. That means there is no oiling or cleaning process: inspect the element during normal service and replace it when dirty or restricted.
