Featuring a new filtration technolgy so revolutionary that aFe has applied for a patent!

5 layers of progressively finer mesh medical grade cotton guaze with micro fibers that attract smaller and smaller particles as air passes through.

Combined with 2 layers of random-porosity non-woven synthetic polyester fabric with random porosity. Sandwiched by 2 layers of aluminum wire mesh.

100% polyurethane construction with progressive seal

Tall open pleat geometry

1.  Washable/Reusable cotton-synthetic media will not collapse even when wet.

2.  Built-in expandable metal (on selected filters) to prevent collapse under high boost pressures.

3.  Pliable progressive polyurethane seal to ensure tight seal without gaskets or sealant.

     We received many letters asking which high flow air intake systems to use.  We decided to test a number of manufacturers' systems to determine which system was superior.  We tested each system and found systems manufactured by aFe (Advanced Flow Engineering) were the BEST by far.
     Diesel engines use seven times more air than gasoline engines of equivalent size so clean cool air is a must for extended engine life, better fuel economy, and additional power.  A higher flow of intake air coupled with a high flow exhaust system allows for more power, a better fuel economy, extended engine life and reduced exhaust temperatures.  On the other hand ingested dirt through the air intake system becomes Silicon in the engine oil, which is a harsh cutting agent and can damage your engine quickly.
     We tested three very popular systems.  We evaluated the systems by a number of criteria, filtration protection, flow, design, ease of installation, and cost.
     Two manufacturers claimed their systems delivered cleaner air at a higher flow, but this was far from the truth.  We did not believe any of the manufacturers' claims and tested each system by operating the vehicle 3,000 miles and performing an engine oil analysis performed at every oil change so they had a Silicon number of three (3) to base their tests on.
I installed the Pro-GUARD 7 filter, changed the engine oil and operated the vehicle for three thousand miles.  The engine oil analysis was excellent with a Silicon reading of below three (3).  Finally we found an air intake system that gave us a higher flow rate and better filtration.  The aFe Magnum Force air intake system is a well-designed system, easily installed and uses about 90% outside air.  The filter is cleanable and the oil used to coat  the filter is patented because it is formulated not to affect the airflow sensor.
     Another positive factor of the high flow system was the fuel economy increased about 1/2 MPG in mixed driving and 1 MPG during highway tests.  The filter media used by aFe will not collapse if it gets wet of subjected to high boost pressures.....

When you use your vehicle in a severe duty or work application, it is important to give the engine a high level of protection from dirt and dust. With 7 layers of media, Pro-GUARD 7 is able to offer a level of protection to the engine that is unsurpassed. Even fine dust is effectively filtered out and kept from entering the engine intake. When the vehicle need to make it through the long haul, Pro-GUARD 7 will offer the protection you need.

Efficiency refers to a filters ability to efficiently filter out the dust and dirt particles from entering the air intake of the vehicle. Pro-GUARD7 was developed with the need for high efficiency in mind. With a filtration media that is able to stop the coarse and fine particles of dust from entering the engine. Typical performance/cotton gauze filters will give you the air flow you need, but have to sacrifice efficiency to do so. The Pro-GUARD7 filters can offer both a high air flow along with the high efficiency you need.

Holding more dust simply means that you will end up with a longer interval before needing to service your filter. In fact, a Pro-GUARD 7 filter can hold over 11 times the dust of a paper filter before needing to be cleaned or serviced, without degrading engine performance. The layers of cotton and synthetic media are able to hold the dirt while still allowing air to pass through. The single layer of a paper filter becomes plugged as soon as a dirt particle deposits itself onto the filter media...that means less air getting to your engine.

The less often a filter requires cleaning or service, the better. Especially considering the maintenance costs involved with work and fleet vehicles, minimizing the frequency of maintenance and getting a longer life out of any part is a benefit to the bottom line. Because of the excessive dirt holding capacity of the Pro-GUARD7 filter line, typical service interval is 50,000 miles on the road, or 25,000 miles in severe duty applications.

Allowing more cool, clean, unrestricted air flow is a key element in increasing engine performance. Pro-GUARD7 filtration technology allows air flow that matches the performance of cotton-gauze filters. Increasing the amount of air the engine can bring in, and doing it with less restriction increases horse power and torque. It can also increase mileage and lower exhaust gas temperatures depending on the driving environment of the vehicle. Pro-GUARD7 offers this level of performance without sacrificing filtration efficiency.

Giving your engine more power and letting it breath easier translates simply into more power. More horsepower, more torque, faster turbo spool up, and lower EGT's are all the result of letting your engine have the air that it needs. You will especially feel the power when you are towing or climbing a hill.

Extended service interval, higher air flow, and the long term protection help with the total cost of vehicle ownership and operation. Value is more that what you pay for a part. It is a combined look at the total cost of ownership of the vehicle. The Pro-GUARD7 filter and intake line offer tremendous value by increasing power, lowering maintenance costs, and avoiding the continual replacement of disposable filters.
