The aFe MagnumSHIELD Pre-Filter (part 28-10283, black) is a removable wrap that goes over the outside of a performance air filter. It removes large particles like twigs and bugs from the air stream before the air reaches the filter. The wrap is made out of dry weave polyester fabric, and it repels water and dirt with minimal effect on air flow. That matters because it adds protection without choking the intake. The payoff is less frequent filter cleaning: the manufacturer states that pre-filters extend filter cleaning intervals. Because the fabric is washable, owners can clean the wrap with soap and water rather than replacing it.
Fitment is the key buying question. The manufacturer's copy ties this wrap to the aFe Momentum HD intake, and the product designation references the 2x/72-91061 filter family. Each pre-filter is made for the filter it is paired with, so confirm the filter number matches your intake before ordering. Search terms that fit this product include aFe Momentum HD pre-filter, 72-91061 air filter wrap, Momentum HD dust cover, and dry weave pre-filter for Cummins or Ford diesel intakes.
