In general, an air cleaner group filters incoming air before it reaches an engine's combustion chamber, helping keep abrasive dust and debris out of the intake path. In heavy equipment, clean intake air supports consistent engine operation in dusty job sites.
Use part number 2590254 as the reference for this air cleaner group entry. The catalog record ties it to the C9 application and to serial number C9E1 and up, so confirm the engine serial number and your machine's configuration against the listing before ordering.
