Sports air filters. Filters of zero resistance K&N.

All K&N intake systems are designed to minimize inlet losses, they literally “smooth” and straighten the air flow. This allows your motor to "inhale" a larger volume of air compared to a conventional filter.

The function of the air filter is to clean the air before it enters the engine. Why is it that almost all racing engines, especially professional racing cars, are not equipped with air filters. The thing is inlet air resistance. The fact is that the more air resistance, the more engine power is lost. Maintaining an optimal, unlimited flow becomes a problem when air must pass through the filter element. Conventional paper elements have great airflow resistance because the filter material is very dense. The greater the resistance, the greater the loss of power.

K&N engineers have achieved great results in the design of sports air filters. In the late 60s, K&N began to impregnate cotton gauze with an oil filter, which exceeded the minimum filtration standards with a slight restriction of air flow. As a result, the first filter element was made of several layers of surgical gauze located between two sheets of wire mesh. The material was compressed to reduce the size of the filter and increase its surface area. Finally, cotton gauze was impregnated with a special oil to increase the filtering ability. The initial concept of filter manufacturing exists today. The cotton gauze filter element is the basis of the K&N filter. K&N filters occupy a leading position in the production of reusable sports filters. The K&N filter lets in at least 50% more air than conventional regular filters without compromising filtering ability.

Why is K&N SPECIAL?

Filter Cleaner

An external inspection of the filter shows large openings in the filter material - this is the main reason for the high air flow throughput. The filter is made of layers of surgical cotton gauze with oil impregnation sandwiched between an aluminum mesh.

The special oil composition in cotton gauze does not limit the throughput and at the same time provides high-quality filtration of the air flow. This is the basis of a unique filtration system! Dust particles attracted to the filter in the air stream have a negative charge and, when passing through the filter element (like a magnet), they are attracted and attached to the impregnated cotton gauze with a positive charge.

With a large accumulation of trapped particles on the outside of the filter, the holes in the gauze tissue remain open. This external level of dust and sand becomes a secondary element of the filtering of incoming particles and at the same time provides high throughput. This simple but very effective secondary filter is the basis of a long filter life, in many cases up to 10 times longer than a regular filter. A 100,000 miles filter is maintenance free and this is the 'norm'. Cleaning is carried out on a run or if, the accumulated layer of contamination is 2mm - 3mm.

MYTHS ABOUT K&N AIR FILTERS

Filter Cleaner

In the automotive community, the judgment about the poor filtering ability of sports filters due to reduced airflow resistance is very popular. This is fundamentally wrong. The filtering efficiency of regular air filters depends on the porosity of the material from which they are made. The lower the porosity, the better the filtering ability of the element. This is precisely the problem of high airflow resistance.

The oiled cotton filters used at K&N function in a completely different way than the regular air system. Proven scientific principles are applied in the manufacture of K&N filters, which determine how an air filter removes dirt particles from air currents. The first of these principles is known as interception, which applies to dirt particles traveling with the air stream. The air flow will always find the shortest path and as air passes through the filter fibers, some of the particles will come into contact with the fibers and be “trapped”. These particles will be retained in the fibers of the filter element through the use of special impregnation.

Another principle is known as impaction, which mainly affects large or heavier particles of dirt. Impaction is when inertia or momentum causes a particle to deviate from the total air flow. In other words, heavy particles do not follow the air flow past the filter fibers, but instead they directly enter the fibers.

The most important principle for developing a K&N filter is the laws of physics that control the movement of very small particles of dirt. Small particles are affected by forces in the air. For example, the forces of velocity changes, pressure changes, a storm caused by other particles and interaction with air molecules cause very small particles to move randomly and randomly, contrary to the main air flow,. As a result, these particles do not follow the air flow, and their random movement causes them to collide with the filter fibers.

A conventional paper filter is able to filter the air flow directly on one surface. Unlike conventional filters, the K&N element has a greater advantage due to its multilayer impregnated surface and better element configuration. This feature allows the K&N air filter to trap more dust.

What do air filters do? Filters purify the air before it enters the engine. The more cold air you can drive into the engine, the more power it will give out, provided that the air-fuel mixture is optimal. It follows that if you replace the standard air filter with one that can let more air pass through it, you will increase engine power, and there is no miracle in it!

Air filters

Induction shield for Injection vehicles - it looks like a mushroom hat and are installed on the oxygen sensor pipe in place of the standard box with a flat filter. For these filters, there are special flushes that allow them to restore their properties and the ability to use for many hundreds of thousands of kilometers. (recommended filter cleaning after 100,000 km) After installing such a filter, a little more induction noise and a few extra horses (5-10 hp for injection cars) will appear under the hood, and torque will also be added in the medium and low revs , All this will increase the elasticity of the engine and improve acceleration dynamics .

Appearance - These filters look very impressive under the hood, in addition, you get rid of the bulky body of the air filter and the tube (duck) through which air is sucked in. This creates a cleaner look under the hood and the filter itself looks 100% complete.

Resistant to moisture and dirt - The air flow will pass (the filter will breathe) even if the filter element is completely dirty or wet, which can not be said about polluting particles and moisture, they will not go beyond oil impregnation.

Power - If you have modified the head of the block, increased engine size, or even just a standard engine, then replacing the filter with K&N with minimal aerodynamic air resistance will allow it to fully breathe. You will get an increase in power from 5 to 10 hp depending on the degree of refinement of the engine and improve the purge of your engine. For forced and not only engines, this is an extra opportunity ~ to improve the acceleration result to 100 by ~ 1 sec.

Durability - Buying a filter, you are freed from the need to change it every 15000, which means you buy it for life. The filter has a guarantee for 1,600,000 km, it is washed with a special compound in case of contamination after 75,000-160,000 and again, like a new one, it can be used without losing its original properties. In addition, K&N filters extend the life of your motor, because one of the main qualities of a good filter is to prevent the smallest particles from entering the engine, thanks to its impregnation and filter element, the filter retains all the smallest particles at the lowest possible aerodynamic drag, thereby protecting the system from blockage and piston from possible damage.

Air filters

Induction noise - It's worth it if YOU are a real car fan, and for you the ability to listen to how your motor breathes is tantamount to music. Well, if the head is modified, there is a high camshaft, then the sound at high speeds will be just fantastic, the car will sound like SPORT BIKE or Rocket.

K&N are sports air filters, the requirements for which are very high in production, because in addition to max protecting the engine from the smallest particles, sand and dust, you also get an advantage in power and dynamics, as well as the opportunity to make your car unlike any other! !!

To select a filter, you must contact the manufacturer’s website , copy the code, send it to us - for a non-standard filter. Or tell the parameters of your car (g / in, make, volume and marking of the engine, type of fuel) - to select a standard filter. In any case, you can just contact us to get a consultation.
