Sport air filters. Filters zero resistance K & N.

All K & N intake systems are designed to minimize intake losses; they literally “smooth out” and straighten airflow. 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 almost all racing engines, especially professional racing cars, are not equipped with air filters. It's all about the intake air resistance. The fact is that the more air resistance, the more engine power is lost. Maintaining an optimal, unrestricted flow becomes a problem when air must pass through the filter element. Ordinary paper elements have high 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 filter air filter with 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 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 soaked in a special oil to increase the filtering ability. The original concept of the manufacture of filters exists today. Cotton gauze filtering element - the basis of K & N filter, K & N filters occupy a leading position in the production of reusable sports filters. The K & N filter allows at least 50% more air to pass through than regular standard filters without reducing the filtering capacity.

Why is K & N SPECIAL?

Filter Cleaner

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

Special oil composition, which is in cotton gauze does not limit 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 in the air flow attracted to the filter have a negative charge and passing through the filter element (like a magnet) are attracted and attached to the soaked cotton gauze which has a positive charge.

With a large accumulation of delayed particles on the outside of the filter, the holes in the gauze fabric remain open. This external level of dust and sand becomes the secondary filter element of the incoming particles and at the same time ensures 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. 100,000 miles filter does not require maintenance and this is the 'norm'. Cleaning is done by mileage or if the accumulated pollution layer is 2mm - 3mm.

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 filtration efficiency of 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 precisely the problem of high airflow resistance.

Lubricated cotton filters used in K & N function completely differently than the standard air system. In the production of K & N filters, proven scientific principles are applied that determine how the air filter removes dirt particles from the air flow. The first of these principles is known as "interception", which is applied to particles of dirt traveling with an 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 "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 larger or heavier dirt particles. 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 fibers of the filter, 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 flow. For example, the forces of speed changes, pressure changes, a storm caused by other particles and interaction with air molecules cause very small particles to move randomly and erratically, despite the main airflow,. As a result, these particles do not follow the air flow, and their erratic movement causes them to collide with the fibers of the filter.

A conventional paper filter is capable of filtering airflow directly from 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 trap 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 out, provided that the fuel-air mixture is optimal. From this it follows that if you replace a standard air filter with one that can pass more air through you, you will increase the power of the engine, and there is no miracle in it!

Air filters

Induction shield for Injection a / m - it looks like a hat of the fungus and installed on the nozzle of the oxygen sensor in place of a regular box with a flat filter. For these filters there are special washes that allow them to restore their properties and the ability to use them for many hundreds of thousands of kilometers. (Recommended cleaning of the filter after 100,000 km) After installing such a filter, you will have a little more induction noise under your hood and a few additional horses (5-10 hp for injection cars), as well as increased torque in the area of ​​medium and low rpm. All this will increase the elasticity of the engine and improve the acceleration dynamics .

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

Resistant to moisture and dirt - Air flow will pass (the filter will breathe) even if the filter element becomes completely dirty or wet, which cannot be said about the contaminating particles and moisture, they will not go beyond the oil impregnation.

Power - If you have a modified head unit, increased engine size or even just a standard engine, then replacing the filter with K & N with minimal aerodynamic air resistance will give it the opportunity to breathe fully. 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 high-powered engines and not only, this is an extra opportunity ~ to improve the acceleration result by up to 100 seconds by ~ 1 sec.

Durability - When you buy a filter, you are freed from having to change it every 15,000, which means you buy it for life. The filter has a warranty of 1,600,000 km, is cleaned with a special compound in case of contamination after 75,000-160,000, and again as a new one 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 resistance, thereby protecting the system from blockage and piston from possible destruction.

Air filters

Induction noise - It's worth it, if YOU are a real avtofanat, and for you the opportunity 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 revs will be just fantastic, the car will sound like a BIKE SPORT or a Rocket.

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

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