Q1. How can I tell whether I have a Pro5R/ProGuard7 oiled or ProDryS oil-free filter?

If the filter is blue (Pro5R) or gold (ProGuard7), then it is oiled. If the filter media is grayish white (Pro Dry S), then it not oiled. With conical filters, look at the top. If it has the "aFe" or "Pro Guard 7" logo printed on the end, then it is an oiled type filter. If the filter has Pro Dry – S printed, it is an oil-free filter. Their may also be a part number on the filter. look for a small circle plug on the urethane part of the filter. There will be a part number located on it. Any numbers with 10-, 30-, 24- are Pro 5R, 11-, 31, 21- are Pro Dry S and any filter number beginning in 7 will be a Pro Guard 7 air filter. If you have further questions, please call us directly at 951-493-7155 and we can help you figure out the filter.


Q2. What is the difference between the three media – Pro 5R, Pro DryS and ProGuard7 - that aFe offers?

aFe offers three different types of filter media for most of our filters and intake systems because everyone has different driving conditions and different driving needs. There is the Pro5R, ProGuard7 and ProDryS. There are detailed explanations for these media in other sections of this website. Without going into details of each media, the basically differences are:

1) Pro5R is 5-layers of progressively finer mesh oiled cotton gauze which offers maximum airflow. This media is ideal for those who drive mostly on paved street and highway who want maximum horsepower.

2) ProGuard7 is 5-layers of progressively finer oiled cotton gauze used in the Pro5R media backed by another 2-layers of finer porosity synthetic non-woven media which offers maximum protection. This media is ideal for those who do a lot of unpaved, off-road driving in severe dusty and dirty environments where protection is more important than maximum horsepower. This media is most popular with compression-ignition diesel truck owners.

3) ProDryS is a 3-layer progressively finer porosity synthetic non-woven media, which is oil-free and offers maximum convenience since it does not require re-oiling. This media is ideal for those who don’t want the hassle of re-oiling a filter.


Q3. How do I clean my aFe air filter?

Before you start to clean the filter, determine whether you have an oiled or oil-free filter. See #1. Also have the appropriate cleaning kit for your filter: #90-50500 for gold, #90-50501 for blue and #90-59999 for oil-free. Follow the steps below:

1) Use a soft bristle brush like a paint brush to remove large chunks of debris and dirt from between the pleats. GENTLY TAPPING the filter on the ground to remove any loose dirt being careful not to bend any of the pleats.

2) Spray the cleaning solution that comes in our Restore Kit, on the dirty side of the filter. Let the cleaning solution soak in for about 10 minutes.

3) Rinse the filter from the clean side of the filter to the dirty side. Repeat spraying and rinsing until the water is clear. Since media will be stained, it will not be completely white and may still appear dirty.

4) DO NOT USE A HIGH PRESSURE WATER NOZZLE when rinsing the filter.

5) Let the filter air-dry. DO NOT USE COMPRESSED AIR TO DRY THE FILTER! It may take a couple of hours for a Pro DryS to 12 to 24 hours for a Pro5R depending on humidity and temperature.

6) If you have an oil-free Pro Dry-S filter, the cleaning process is completed and the rest of these instructions can be disregarded.

7) After the filter is dry, apply oil across 6 pleats in a zig-zag pattern, leaving about a 1/2" inch of media un-coloured from the urethane. DO NOT DROWN THE FILTER WITH OIL! The oil will wick out a great deal.

8) Leave the oiled filter for 8 to 12 hours to allow the oil to fully wick. Finally, spot apply oil to areas that still do not have "color" to it.


Q4. What is the difference between aFe filters and other manufacturer’s filters?

We invite consumers to compare our products with others. Here are several things to look for:

1) Media construction: constant mesh or progressive mesh. aFe is the only company that uses a progressively finer mesh media.

2) Pleat design: Tight or open? Pinched or rounded? aFe uses an open, rounded pleat design that allows better airflow through the tops and bottoms of each pleat.

3) Pleat height: Deep or shallow? aFe pleats are 30% deeper pleats than competitors for longer service interval and greater dust holding capacity.

4) Filter seal: Soft or hard? Flat or progressive? Additional sealing gasket or grease needed or not? aFe uses a pliable, progressive bump seal that requires no foam gasket or filter grease.


Q5. What are the differences between an aFe intake system and other manufacturer’s systems?

Here are several things to look for the fit and finish of aFe intake systems:

1) Do you have to assemble the housing? Our housings are usually one piece and come pre-assembled.

2) How many parts are included with the system? aFe minimizes components as much as possible for easier installation.

3) Is any cutting, drilling or modification of the vehicle required? aFe systems use stock mounting points and require no modification to the vehicle.

4) What are the performance numbers? Through the use of molded plastic tubes and 3-angle adaptors that direct airflow more effectively, aFe consistently delivers excellent horsepower and torque numbers. Check out www.afepower.com for your expected performance results.


Q6. What is the warranty on my aFe part?
