FILTER COMPARISON: FOAM Vs. COTTON GAUZE

Filter Comparison

Weapon*R High Density FoamVs.Brand X Cotton Gauze

The most common aftermarket modification is the intake system. The available kits are mostly the similar; they include an aluminum pipe and a cone filter to replace the factory air box and tubing. But as we have shown in our Secret Weapon Test, not all intake pipes are created equal. The Secret Weapon pipes and filters outflow the competition hands down, but a common question is “How well does it filter?” In this article we’ll show you the differences between our Foam Filters, and the popular Cotton Gauze Filter used by many of our competitors. Our contenders for this filter test are:

Secret Weapon High Density Foam filter (SW filter)

• 3”inlet4.75” x 6”4 ply

Cotton Gauze filter (Brand X)

• 3” inlet 10” x 6”

These are the same two filters used in our Secret Weapon flow test. Our first test is to simply show the density of the two filtering media using light. We simply hold the filters up to a bright light source (e.g. sunlight, halogen light), and look for any sign of light showing through. As you can see, the Brand X filter allows light to shine right through, while the SW filter completely blocks out all light from coming through the foam. Any consumer can do this and see all the large pores in the Brand X filter.In the next comparison, we disassemble the two filters to measure thickness of the media. Using a micrometer we measure the media in their uncompressed form.

The Brand X filter measures about 2.36mm, while the SW filter is nearly 7-times thicker at 14.07mm! The Brand X filter only has once chance to catch dirt, and that’s in this 2mm of oil soaked fabric. The SW filter has numerous tiny pores and pathways in which to catch dirt, and uses a light oil to make sure the dirt sticks and never makes its way into the engine. We will have an independent dirt flow test conducted in a future installment.

The final comparison is in the base of the filter. The Secret Weapon Filter uses a full velocity stack to route air into the intake tract, while the Brand X filter uses a molded base with a curved inlet as a velocity stack. The Brand X version has a flat edge all around the velocity stack, while the Secret Weapon velocity stack is raised off the base of the filter to route air from all angles within the filter, and a fully rounded inlet lip to ensure the smoothest pathway for air to flow. This velocity stack is the same design used by many race teams and is proven to increase airflow into the engine.

In addition to all the advantageous features listed above, all of our filters utilize a mesh cage surrounding the foam to keep it being deformed under the heavy vacuum when the engine is revved.This is just a quick look at the advantages of using a foam filter over the common cotton gauze replacement filter. It has been shown that not only does foam flow better, it filters better as well.

Still not convinced? Well consider one of the dirtiest motorsports around, motorcross. These motorcycles are built to play in the dirt, and when their industries choose a performance filter, what do they choose? That’s right, a foam filter. Take a good look around, you’ll see that the claims of foam being inferior to cotton gauze are a very large misconception.

Secret Weapon Short Ram Intake

Short Ram Intake Secret Weapon

• The air filter can be totally taken apart and cleaned. The foam is denser and more thicker than the Dragon filter.
  
• The velocity stank inside the air filter is a TRUE VELOCITY STACK. The Air filter has Ram Air capability, by hooking up the hose to the top of the air filter.
  
• The intake has another Air Passage way inside the intake pipe to create a Air Fusion, imagine 2 different pathways of air inside the intake pipe, one air traveling in pathway #1 going 2 x faster than pathway #2. When the two different pathways of airflow meet at the end of the pipe they create a fusion effect which enhances the AIR SPEED of the by 3 times.

The Secret Weapon Intake Systems is an result of countless hours of testing and tuning of air intake velocity, Airmass and Airspeed for each vehicle application. The Result, an intake system that performs better than any Cold Air Intake, but with a Short Ram. It is possible by Weapon*R's Patent Pending Speed Velocity theory, By creating a higher airspeed in the intake path you increase airmass and airspeed, which greatly increase horsepower.

This is possible by Creating two different paths of airflow, both flowing at different airspeeds, due to the tubing diameter in which the air is traveling. Now when the 2 different paths of air meet,they create a vacuum, which is where the airspeed starts to multiply, forcing more air into the engine at a higher rate, creating more horsepower.

The Secret Weapon Intake Systems are carefully CNC mendrel bent out of 6061 Aluminum, and then Hand Tig Welded in sections to ensure a constant balance in airflow, regulation in airspeed, positive seal and proper fittment. Each one of these intake systems are carefully tuned, by matching the engines displacement, air intake capacity and airspeed to the intake systems tube size,length and secondary pathway tubing diameters to maximize the full potential of the SECRET WEAPON INTAKE SYSTEM. This Intake is Matched with our Newly designed SW1 Filter, which provides maximum airflow, with the protection of high quality dense Poly Urethane Foam.

Many studies have shown Flow rates of up to 80% more Air and Better Dirt Filtration with Foam Filter than the conventional cotton filter. The SW1 main feature is an Computer CAD Designed and Flow benched Tested TURBO Velocity Stack, which greatly increases airflow ,airspeed and airmass into the engine, therefore increasing engine performance. Another one of the SW1 Filters great features are the capability to be dis-assembled to be cleaned and then re-assembled after cleanings or to change the color of the foam filtering element.

What does this all mean?

The Secret Weapon uses two important laws of physics to increase airflow. The first law is Boyles law. This law basically states that as air velocity increases, its volume increases as well, while the pressure decreases. The second law is the Bernoulli Equation, where a moving fluid (in this case air) has a lower pressure than air that is standing still, or is moving slowly. This same law is used in NASCAR for both downforce and "drafting." When we increase the air velocity in the intake, we create a low pressure area that draws a higher volume of air than a standard intake would. In layman's terms, we are creating a vacuum effect using natural laws of physics.

Do the Weapon*R Air Filters, filter dirt better than K&N / AEM / Injen Air Filters?

The Secret Weapon Air Filter is made of Polyeurethane Foam, which is rated at 300 Pores per square inch. Whereas the K&N / AEM / INJEN air filters are rated at 30-60 pores per square inch. This means that there is more dirt particles passing through the air filter to the engine when using their filters.

Why is the Secret Weapon Air Filter so much better?

The reason why the Secret Weapon Air Filter flows much better than any other filter on the market today is because of the specially designed Velocity Stack inside the air filter, it helps gather more air into the air filter and velocitize the air into the intake tube.
