Air Filter Cleaning Kit Blue Oil Aerosol

The AFE POWER Air Filter Cleaning Kit Blue Oil Aerosol (model 90-50001) is a complete maintenance system designed for cleaning and re-oiling reusable engine air filters. This kit pairs a 12-ounce pump bottle cleaner with a 5.5-ounce aerosol oil application system, delivering the dual-stage process required to restore filter performance and extend service life in high-performance and stock vehicle applications.

The cleaner component removes accumulated dirt, dust, and debris from the fiber filter media without damaging the delicate material, while the aerosol oil provides controlled, even coating to re-establish the filter's arrest capacity. This two-part approach is standard across professional and enthusiast air filter maintenance. The pump-spray applicator gives precise control over cleaner distribution, and the aerosol delivery ensures consistent oil saturation—critical because under-oiling reduces filtration efficiency while over-oiling creates airflow restriction and engine performance loss. Users working on track vehicles, off-road builds, or high-mileage daily drivers benefit from periodic filter service, as it maintains peak air intake flow and engine breathing without the expense of filter replacement at every service interval.

This kit serves engine builders, performance enthusiasts, and fleet maintenance shops where filter longevity and cost-per-service matter. Reusable air filters—common in cold-air intake systems, custom engine builds, and commercial fleet vehicles—require regular cleaning and re-oiling to function effectively. The AFE POWER air filter cleaning kit provides a straightforward, economical solution for in-house maintenance without the need to source multiple products or specialty tools.

Kit contents include the 12-ounce pump cleaner bottle, 5.5-ounce aerosol oil, and a fiber filter guide, all packaged for easy storage and repeated use across multiple filter service cycles. AFE POWER, known for performance air intake systems, backs this kit with the same attention to filter care standards that define their broader product line.
