Sport air filters. Zero resistance filters K & N.

All K & N intake systems are designed to minimize the intake losses, they literally "smoothen" and straighten the airflow. This allows your motor to "breathe in" 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, then, almost all racing engines, especially professional racing cars, do not have air filters. It's all about air resistance at the inlet. 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 resistance to airflow, because the filter material is very dense. The greater the resistance, the greater the loss of power.

Engineers of K & N have achieved great results in the design of sports air filters. In the late 60's, K & N began to impregnate the cotton gauze of the air filter with a special oil, which exceeded the minimum filtration standards with a slight restriction of the air flow. As a result, the first filter element was made from several layers of surgical gauze located between two sheets of wire mesh. The material was pressed 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 original concept of making filters is still there today. The filter element with cotton gauze 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 transmits at least 50% more air than regular filters without reducing the filter capacity.

Why is K & N SPECIAL?

With an external inspection of the filter, large openings in the filter material are visible - this is the main reason for the high airflow capacity. The filter is made of layers of surgical cotton gauze with oil impregnation, sandwiched between an aluminum mesh.

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

With a large accumulation of delayed particles on the outside of the filter, openings in the gauze tissue remain open. This external level of dust and sand becomes a secondary element in the filtration of incoming particles and at the same time high throughput is ensured. This simple but very effective secondary filter is the basis for a long filter service, in many cases up to 10 times longer than a conventional filter. 100,000 miles filter does not require maintenance and this is the 'norm'. Cleaning is carried out by mileage or if, the accumulated layer of contamination is 2mm - 3mm.

In the automotive community is very popular opinion about the unsatisfactory ability of filtering sports filters due to reduced resistance to air flow. This is fundamentally wrong. The efficiency of filtering the standard air filters depends on the porosity of the material from which they are made. The smaller the porosity, the better the filtering capacity of the element. This is the problem of great resistance to air flow.

Lubricated cotton filters used in K & N function completely differently than the regular air system. In the production of K & N filters, there are proven scientific principles that determine how an air filter removes dirt particles from the air flow. The first of these principles is known as "interception", which is applied to particles of mud traveling with air current. The air flow will always find the shortest path and as the air passes through the filter fibers, some of the particles will come into contact with the fibers and will be "captured". These particles will be retained in the fibers of the filter element by using a special impregnation.

Another principle is known as impaction, which mainly affects large or heavier dirt particles. Impaction is when inertia or momentum causes the particle to deviate from the total airflow. In other words, heavy particles do not follow the air current past the filter fibers, but instead they fall directly into 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 current. For example, the forces of speed changes, pressure changes, the storm caused by other particles and interaction with air molecules cause very small particles to move randomly and chaotically, contrary to the basic airflow,. As a result, these particles do not follow the air current, and their erratic motion causes them to collide with the filter fibers.

A conventional paper filter is capable of filtering the airflow directly by one surface. Unlike conventional filters, the K & N element has a greater advantage due to the multi-layer impregnated surface and better element configuration. This feature allows the K & N air filter to retain more dust.

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

Air filters

Induction shield for Injection cars - it looks like a mushroom hat and is mounted on the tube of the oxygen sensor in the place of the standard box with a flat filter. For these filters there are special washes that allow them to restore their properties and the ability to use for many hundreds of thousands of kilometers. (The recommended cleaning of the filter after 100,000 km) After installing such a filter, you will have slightly more induction noise and a few additional horses (5-10 hp for the injector cars) under the hood, and also add torque in the middle and low speed range , All this will increase the elasticity of the engine and improve the overclocking dynamics .

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

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

Power - If you have improved the head of the unit, increased engine capacity or even just a standard engine, then replacing the filter with K & N with minimal aerodynamic resistance of the air will give it a chance to breathe fully. You will receive an increase in power from 5 to 10 hp. Depending on the degree of completion of the motor and improve the purging of your engine. For forced and not only engines, this is an extra opportunity to improve the acceleration result by 100% for 1 second.

Longevity - When buying a filter, you are freed from the need to change it every 15,000, which means you are buying it for life. The filter has a guarantee of 1,600,000 km, is washed by a special compound in case of contamination after 75,000-160,000 and again as new can be used without losing its original properties. In addition, K & N filters prolong the life of your motor, because one of the main qualities of a good filter is to prevent the smallest particles from getting into the engine, due to its impregnation and filtering element, the filter delays all small particles at the lowest possible aerodynamic resistance, thus protecting the system from Clogging and piston from possible damage.

Air filters

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

K & N is a sports air filter, the requirements for which are very high in production, because besides the maximum protection of the engine from getting into it the smallest particles, sand and dust, you get also an advantage in power and dynamics, as well as the ability to make your car unlike others! !!

To select a filter, you need to contact the manufacturer's website , copy the code, send it to us - for a non-standard filter. Either inform the parameters of your car (y / in, mark, volume and marking of the engine, type of fuel) - to select a regular filter. In any case, you can just contact us to get advice.
