AFE Magnum Force Pro Dry S Cold Air Intake System

Advanced Flow engineering offers you a better choice of oil-free filters: New Pro Dry S synthetic dry-media 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. 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 gas and diesel trucks, SUVs, and car.

Will aFe air filter void my factory warranty?

There is a law known as the Magnuson-Moss Warranty, that prohibits a manufacturer from void a warranty simply because you did not use a specified air filter. They must prove how the filter actually caused the problem.

How can I tell when the filter need to be cleaned? A good rule of thumb is to clean the filter when you can barely see the aluminum mesh. Most people clean the filter too often. It's not necessary to clean the filter too often. In fact, cleaning the filter too often will shorten the filter life and prevent the filter from reaching it's maximum filtration efficiency. Even thought the filter looks dirty, if you can see the aluminum wire mesh, it's still clean enough and plenty of air is still going through..

What is the difference aFe's filter and those of other MFGs?

There are some subtle but significant differences between aFe’s filters and others. The best way is to take two filters for the same application and compare them. Here are some points to look for:
1. Filter media – aFe filter media is a 5 layer progressive mesh media on our standard high performance filters and 5 plus 2 more on our high filtration Pro-GUARD 7 media.
2. Pleat height and pleat spacing – aFe is generally 25% taller and more openly spaced. More open the pleats are the better the airflow. However, more openly spaced the pleats are fewer pleats you have. To have maximum filtration media, aFe offsets fewer, more open pleats with taller pleats.
3. Pleat shape – aFe pleats are more rounded like a dolphin’s nose rather than pointed. Rounded pleats allow air to flow through the tops and bottoms of the pleats themselves.
4. Seal shape – aFe uses a progressive bump seal made of 100% engineering grade polyurethane. The urethane stays soft and pliable over time and resists chemical and heat degradation.
5. Degree of wicking – “Wicking” is the amount of polyurethane that is absorbed by the cotton gauze media during the manufacturing process. Polyurethane that is absorbed into the media blocks airflow through that portion of the media. AFe strives to minimize the amount of “wicking” on all its filters.
