New Pro Dry S synthetic dry-media filters; a better choice of oil-free filters. Pro Dry S filters use a revolutionary two-ply synthetic material that is functionally superior to traditional paper media and single-ply synthetic, and easy to service. aFe's Pro Dry S filters provide performance and protection with quality and affordability. Our new dry-media filters use the same quality construction you have come to expect from aFe, but cost less than our standard-media filters. Our two-ply synthetic dry media is sandwiched between an inner and an outer aluminum mesh barrier that provides support and protection, eliminating the need for extra internal structures. The base and top-cap are made of premium-grade urethane and poured up to twice as thick as other filters. The end result is a top-quality product at a value price that any vehicle owner will be proud to own.
Traditional paper filters restrict airflow through a vehicle’s intake system, limiting the engine’s power potential. aFe's Pro Dry S dry-media filters increase airflow providing improved throttle response, horsepower, torque, and fuel economy. And at 99.4%* filtration levels, Pro Dry S filters accomplish all this without sacrificing engine protection.
Perhaps the greatest benefit of new Pro Dry S filters is the convenience of servicing these oil-free filters. Most traditional paper filter manufacturers suggest that filters be changed at least every 12,000 miles. Pro Dry S filters have service intervals of up to 50,000 miles in standard driving conditions. Just imagine the convenience of servicing your filter one-fourth as often. And because the filter is oil free, service is easier and less time-consuming. To clean a dirty Pro Dry S filter lightly tap it on the ground or vacuum with a standard house or shop vacuum. A vacuumed Pro Dry S filter will return to 95% of its original performance and airflow characteristics. For a full cleaning the filter may be washed with soap and water to return it to near-new condition and 100% airflow capacity. Costly solvents and cleaning kits are not required to clean our new Pro Dry S filters.
Pro Dry S dry-media filters by aFe are now available on all of our popular air intake systems for diesel trucks. Replacement Pro Dry S filters for all air intake systems are also available and sold individually.
The revolutionary new dry synthetic media is easy to clean, and offers three cleaning options:
Tap Clean: You can tap your Pro Dry S filter and return it to 85% of its original airflow. Simply remove the filter from the intake kit and lightly tap it on a solid surface. Tap and turn the top and bottom of the filter until most of the visible dirt has been released. Reinstall the filter in your vehicle. Do not apply oil to the filter.
Vacuum clean: You can vacuum your Pro Dry S filter and return it to 96% of its original airflow. Remove the filter from the intake kit and vacuum away the dirt using a shop vacuum or regular house vacuum. Reinstall the filter in your vehicle. Do not apply oil to the filter.
Wash clean: You can wash your Pro Dry S filter and return it to 100% of its original airflow. Remove the filter from the intake kit. Run the filter under running water from the inside out. Turn the filter to remove all visible and hidden dirt. If your filter is coated with grease or road grime, it may be necessary to use soap and water to get it fully clean. You can completely submerge the filter in a mixture of warm water and mild detergent (use a common household detergent such as dish or liquid laundry soap) if needed. Rinse clean. Allow the filter to dry completely (our synthetic media dries quickly and should dry within a few hours in normal conditions). Reinstall the filter in your vehicle. Do not apply oil to the filter.
