Replacing a worn stock filter with the aFe AFE72-91115 restores the layered cotton gauze and synthetic media that dual inlet Momentum intake systems depend on for consistent airflow. The tall, evenly spaced pleats hold more dirt between cleanings while the inverted conical shape keeps the intake tract free of restriction.

Advanced Flow Engineering has built cold air intakes and replacement filters in Corona, California for decades, focusing on layered media construction that balances filtration efficiency with high airflow for performance applications.
It is an aFe Momentum replacement air filter using Pro-GUARD 7 media, built with dual 3in front inlets, an 8.25in x 6.25in base, a 7.25in x 5in top, and a 9in height for direct fitment into compatible Momentum intake housings.
Is this filter washable and reusable?Yes, the Pro-GUARD 7 media is designed to be cleaned and re-oiled repeatedly rather than replaced after each service interval.
How often should this filter be cleaned?aFe recommends cleaning and re-oiling every 20,000 to 30,000 miles, or sooner in dusty or dirty driving conditions.
What cleaning kit does this filter need?Pro-GUARD 7 filters use the gold aFe Restore Kit cleaner and oil, which matches this media type specifically.
Can this filter be run without oil?No, Pro-GUARD 7 is an oiled media and must never be run dry, since the oil is what captures fine particles.
Does this filter fit a stock air box?This filter is shaped for Momentum intake housings with dual 3in inlets rather than a factory air box opening.
What is the difference between this and a Pro DRY S filter?Pro-GUARD 7 is an oiled cotton and synthetic media with more layers for maximum filtration, while Pro DRY S is a dry synthetic media that skips the oiling step during cleaning.
How long does this filter last?With proper periodic cleaning and re-oiling, this filter is built to last the life of the vehicle it is installed on.
