The aFe MagnumSHIELD pre-filter, part 28-10113 in black, is an outer sleeve that fits over a performance intake filter and catches debris before it reaches the element. This pre-filter does not restrict air flow and is made of a dry weave fabric that does not attract dirt and cleans with soap and water. The aFe POWER logo is silkscreened on the sleeve, so the intake's source is visible at a glance.
The payoff is debris management. aFe's Magnum SHIELD pre-filters protect the performance air filter by removing large debris particles, resulting in extended service intervals. The manufacturer also positions the line for dirty or off-road environments, where a clogged element is the most common reason to pull the filter early. Each sleeve is designed around one specific paired filter, so you get a matched fit instead of a generic wrap that may not seat properly.
Fitment depends on the filter number, so check yours first. The manufacturer's listing covers the 2x-90015/23 2x-91007/8/22 2x-91108 (Black) filter series. Note that the 2x-91108 series is not in the product title, so confirm the full list before ordering. Upkeep is simple: it can be easily cleaned with soap and water, which lets you reuse the sleeve instead of replacing it at every service.
The manufacturer's listing names the 2x-90015/23, 2x-91007/8/22, and 2x-91108 series. Match your filter's exact part number to that list before ordering, because the sleeve is designed for a specific paired filter.
The manufacturer states the sleeve does not restrict air flow. It is intended to add protection without changing how air moves into the filter.
The manufacturer says it can be cleaned with soap and water. Rinse it and let it dry fully before reinstalling it on the filter.
This is a maintenance-level accessory rather than a tuning job. Confirm your filter's exact part number against the compatibility list before you start, since a sleeve built for a different filter will not seat correctly. Clean the sleeve with soap and water at your normal service interval, and keep a spare on hand if you regularly run in dusty conditions.
