Caterpillar Air Filter Kit | Parts 415-2592 & 415-2593

Dual-Stage Engine Protection for D-Series and E-Series Machines

Maintain the performance and longevity of your compact equipment with this heavy-duty radial seal air filter kit. This two-piece set includes the Primary Air Filter (415-2592) and the Secondary Safety Filter (415-2593), working together to provide a total barrier against dust, soot, and abrasive job-site debris.

Designed specifically for Caterpillar’s latest generation of compact track loaders and mini excavators, this kit ensures high-volume airflow for efficient combustion while protecting the engine during filter changes. Regular replacement—typically every 500 to 1,000 hours—is essential for maintaining fuel economy and preventing premature turbocharger wear.
