Show original supplier description
The aFe Power 21-91020V is a replacement air filter engineered to fit aFe POWER Magnum FORCE intake systems. This filter utilizes D2 Dura-Dry media, which is designed for optimal airflow and filtration performance. The inverted conical shape provides a large surface area, contributing to extended service intervals and efficient air intake. Specifications for this filter include a 4-inch base diameter, a 4.5-inch top diameter, and a total height of 6 inches. The D2 Dura-Dry media is a key feature, offering a balance between high airflow and effective dust and debris capture without requiring oil for filtration. This air filter is not vehicle-specific and is intended as a replacement part for compatible aFe POWER Magnum FORCE intake systems. Customers are responsible for confirming the fitment with their specific intake system part numbers, such as 54-83038R and 54-83038D, as noted in some product listings.
