This black round pre-filter slips over the outside of a matching aFe performance air filter. aFe POWER Magnum SHIELD Pre-Filters protect your performance air filter by removing large debris particles, resulting in extended service intervals. That makes it a practical add-on for drivers who run gravel, dusty trails, or desert washes. Made out of dry weave polyester fabric, the pre-filter repels water and dirt with minimal affect on air flow. The aFe POWER logo is silkscreened on the outer face, so the intake stays identifiable under the hood.
Compared with running a bare performance filter, a pre-filter takes the coarse grit so the filter element itself stays cleaner for longer. Cleaning is simple: it can be easily cleaned with soap and water. Rinsing the wrap is far cheaper than replacing a filter that has been loaded with dust. Because the pre-filter is sized to a specific filter, it should be matched to the 24-91031 black filter it is meant for rather than swapped onto an unrelated element. Searchers looking for an aFe 28-10153 pre-filter, a MagnumSHIELD P/F 24-91031 black wrap, or a dry weave polyester pre-filter for off-road air intakes will find this part matches those needs.
No. The manufacturer says each pre-filter is made for the specific filter it is paired with, so confirm that your filter is the 24-91031 black designation before ordering.
The manufacturer describes its effect on airflow as minimal, so the wrap is intended to protect the filter without meaningfully restricting it.
The manufacturer states it can be cleaned with soap and water, which is how it is maintained between uses.
Installation is a slip-on job. The manufacturer notes the pre-filter has pull tabs for quick installation, so you simply stretch it over the paired filter before reinstalling the filter in the intake. Confirm the filter pairing first, since the wrap is sized to a specific filter. Before reinstalling, make sure the wrap sits evenly on the filter so it does not interfere with the airbox lid or intake tube.
