Liquid Filtration Heads & Filters servicing problems are:
Two of the most common air cleaner

1. Over-servicing: the least efficient time in the life of
the filter is when it is new. Filter elements increase

in efficiency as dust builds up on the media.

2. Improper servicing: your engine is highly vulnerable
to abrasive dust contaminants during the servicing

process when the filter is removed from the
housing. A leading cause of engine damage is due

24 to careless servicing procedures. Ref: Shoptalk Card F115236 & Air Cleaner Catalog F110027 / Auto Parts
