Currently, there are many types of car tuning. Especially popular with many car owners is the modification of the motor part of the car. Most often, motorists resort to installing a cold inlet, as a result of which cold air begins to flow into the engine. Almost every car owner dreams of his car moving faster, and the motor in the traffic jam vibrating as little as possible. However, not everyone knows that it is possible to make a modification by installing a cold inlet. And not everyone understands what a cold inlet is. The pros and cons of the system, as well as installation options for some cars will be discussed in this article.
What it is
The cold intake system allows the cylinders to be filled with cool air, thereby increasing the efficiency of the engine.
It includes a filter of zero resistance, nozzles. Also subject to reconstruction is an air filter box, an
intake manifold and a
car receiver.Principle of operation
For the system to work, it is necessary to install a filter outside the hood, in a well-closed area from dirt or dust. At the same time, it is necessary to install in the part where a good stream of cool air is observed. The air entering the nulevik is piped to the intake system, where, due to the lower air temperature, the best combustion of the incoming fuel occurs. As a result, the efficiency of the unit increases.
Installation advantage
One of the ways to increase the power of a car is considered to be installing a cold air intake system. However, each of the systems has its advantages and disadvantages. Among the advantages we note:
- Power increase.
- Increased sensitivity of the gas pedal.
- Reduced fuel consumption.
- Uniform work of the unit.
Cons of a cold inlet
Among all the disadvantages of installing a cold inlet, there are:
- The appearance of strong noise from the zero filter.
- If the installation technique of the system is not followed, water hammer may occur. Water hammer can also occur due to improper operation of the vehicle.
- The installation process is quite time-consuming.
- Change in standard equipment.
- The use of low-quality "nuleviks" leads to engine damage.
Kinds
Currently, many tuning studios are selling various types of cold intake systems.
All of them differ in color, size, materials used in the manufacturing process. The choice of system is only at the request of the motorist. Some manufactured items can be manufactured directly for a particular brand of car, while others are manufactured as a universal device.
Currently, the most common intake systems are:
- Cold Air Intake.
- APR Carbonio.
- K&N.
- Takeda.
- AEM.
It is worth remembering that if there is no desire to buy expensive ready-made kits and spend money, you can make a cold inlet with your own hands.
System on a Subaru car
Subaru cars were originally distinguished by good power and high-torque. However, some motorists decide to alleviate the fate of the motor and install a cold inlet so that the engine can work with better efficiency without much wear.
To install the cold intake system, you must select the location of the intake manifold. As a rule, most car owners of Subaru Impreza install this pipe on the right side, removing the resonator from under the wing. According to motorists, there is no need to fear for the removal of the resonator. There will be no consequences in the form of a water hammer or a quick failure of the filters. To install a cold inlet with your own hands (including Subaru Legacy), you must buy a ventilation aluminum corrugation with a diameter of 80 mm. The passage through the cavity has a diameter of 73 mm. However, this does not hinder to easily install the corrugation. It should be taken meter. Gently pulling the corrugation through the holes, we attach it to the box of the air filter. In other places, it is installed using ordinary coupling clamps. As a result, the element is displayed in the bumper compartment, where the fog plugs are installed.
For greater attractiveness, you can neatly cut a hole in the PTF plug that the pipe will connect to. It is worth remembering that in this case it is necessary to put on a protective mesh so that the air filter lasts as long as possible. As a result, at low speeds, the car will behave much better.
Cold inlet, Honda
Many car owners of Accord cars are faced with the problem of hard failures of a hot engine car. To fix the problem, most of the drivers decide to install a cold inlet on the car. For installation, it is necessary to purchase additional gaskets for the collector. It is possible to facilitate the flow of cold air by turning off the heating of the collector. The heating is switched off by sawing off part of the collector, where the idle valve was located , and where antifreeze entered the channels. Having removed the collector on the right side of the head, it is necessary to make a thread in the channel in order to install a plug there as a result. After threading , remove all chips. In the collector, the existing hole must immediately be covered with epoxy glue or welded using argon welding. You can cut off the excess part with a grinder. Then we install the parts in their places. In addition, the inlet pipe must be brought out under the wing. A specially bent tube of the required diameter can be ordered exactly under the "Accord". A zero resistance filter is also installed under the wing instead of the resonator there.
Honda cars have gills on the inside of the wing. To keep the filter always dry, these gills should be sealed with a dense material. Soundproofing material is well suited. In addition, a special protective cover is installed on the filter, and if there are holes in the bumper, an additional protective mud screen must be made. In order to prevent hot air from accessing the filter, it is necessary to install a special thermal protection plate from the engine side. It is worth considering the fact that the zero filter must be washed every 5 thousand kilometers. Run on a car will be problematic, since every time you need to remove the bumper. Thus, it is not so difficult to install a cold inlet with your own hands (Accord 7, including). The main thing is to stock up with patience, material and straight arms.
Cold intake system on Kalina
Many domestic car owners, especially young people who love fast driving, are trying to make a cold inlet on their own. As an example, it is enough to consider the Lada Kalina car. In order to make a cold inlet with your own hands on the Kalina, it is not always necessary to install a filter of zero resistance, it is enough to bring a cold air intake to the original air filter box. On the Kalina, cold air enters through the left headlamp. This is due to the fact that it is there that the greatest air resistance occurs, which literally "flies" into the filter.
Instead of the existing high beam bulb, it is necessary to install a corrugation. You can choose a ventilation or special, which is mounted on the car from the pre-heater. The inner diameter of the hose is 50 mm. In this case, the inside should be smooth so as not to impede the flow of air. One end of the corrugation is connected in the headlamp, the other with a hole made in the duct of the air filter. The main inlet pipe to the duct should be dismantled, and the inlet should be closed with a plug. In order for condensate to drain, it is necessary to make several holes in the lowest places. In such a simple way, a cold inlet will be installed on the Kalina. Pros and cons (VAZ-2172 including also lends itself to a similar upgrade) it, in contrast to the installation of the system, is that the engine ceases to emit strong vibration at idle, however, it becomes more difficult to advance a few meters. In addition, in the cool time of the day, the car has increased agility. Also, the car gets faster on the track at a speed set of more than 100 km / h.
The cost of tuning your car is minimal. It is worth remembering that in winter it is recommended to change the air flow to stock. This is done in the usual way: an old corrugation is put on, and a cap is put on a new hole. Therefore, before installing a cold start on the Kalina, think carefully, as in this case you will have to lose one high-beam bulb and remodel the headlight a bit.
Summary
In some cases, the installation of ready-made kits requires not only experience, but also takes a long period of time, since installation requires a search for the most convenient mounting location in the engine compartment. It is worth noting that it is justified to install a zero resistance filter only with a complete engine refinement. Otherwise, the opposite effect will be observed - a drop in power.
So, we found out the advantages and disadvantages of this type of tuning. As you can see, you can set a cold start yourself, significantly saving at the same time.
