aFe MagnumFLOW Pro 5R Replacement Air Filter 20-91206R

This filter features five layers of pre-oiled cotton gauze media to provide maximum performance. Its progressive layering allows the filter to flow at high levels even when dirty, while its inverted top makes for more filter surface area, resulting in longer service intervals. This media is perfect for street and/or track use. Pro 5R filters are easily recharged with aFe's POWER CLEANER and blue air filter oil. aFe POWER performance air filters use a rounded, evenly spaced pleat design which allows for more usable filter surface area, providing increased flow and greater dust holding capacity. This aFe POWER performance air filter is constructed with a polyurethane base and top. Unlike other materials that degrade after repeated heat cycles in an engine bay, polyurethane maintains its original molded shape. Utilizing the filter's external locking tabs, the filter snaps into most Momentum series housings with zero hardware. This patent pending interface allows for easy filter maintenance and replacement.

The aFe MagnumFLOW Pro 5R replacement air filter is designed for Momentum intake systems requiring a high-flow, washable, and reusable filter. Part number 20-91206R uses five layers of pre-oiled cotton gauze media to support strong airflow for street and track applications. Its progressive media design continues flowing efficiently as the filter accumulates dirt, while the inverted top increases usable filter surface area for longer service intervals.

Rounded, evenly spaced pleats help maximize airflow and dust-holding capacity. The filter features durable polyurethane construction at the base and top, which helps it retain its molded shape through repeated engine-bay heat cycles. External locking tabs allow the filter to snap into compatible aFe Momentum housings with minimal hardware, simplifying maintenance and replacement. The included stainless steel clamp helps provide secure installation where required.

For extended service life, the aFe MagnumFLOW Pro 5R can be cleaned and reused through multiple maintenance cycles. Restore the filter with aFe POWER CLEANER and blue air filter oil.
