Air filter tuning falls into the category of Engine tuning. In principle, an increase in engine performance is the goal that you want to achieve with the change to the filter. After that comes the factor intake noise. Drive power can be increased by increasing the airflow in the engine, allowing more fuel to be burned in less time. Air Filter can be exchanged or retrofitted on the car, motorcycle or truck. However, most well-known tuners rate the real benefit of the increase in engine performance as rather low. At least if no further modifications like a Chiptuning, Turbo- od. Compressor upgrade or other things that come with it. which Advantages and disadvantages does the air filter have tuning? And what must be considered during the conversion? Following are the answers.
Air filter tuning - table of fines
| Description | Strafe |
|---|---|
| unnecessary noise pollution from the vehicle | 80 Euros |
| Driving without an operating license | 50 Euros |
What is the benefit of tuning? The goal is to increase the performance of the engine. In principle, more oxygen should be supplied to the engine, which ensures that more fuel is burned. Which vehicles can sports air filters be retrofitted to? This is possible on motorcycles, cars and trucks. In principle, however, on all vehicles that use an air filter ex works. It depends more on the filter manufacturers whether a sports air filter is offered for the vehicle in question. Does the tuning make sense? Often the tuning even leads to a drop in performance, since the layman likes to simply install the filter openly in the engine compartment. Then it often sucks in warm air. What variants are there for tuning the air filter? There are basically two variants on the market that can be used for tuning: the one made of cotton Air Filter, and sports air filters, the open make
Air filter dummies
The testing organizations are increasingly making use of the cars Air filter dummies Celebration. However, the deceptively real-looking filter containers are almost never fitted with a filter. This makes the sound of the engine more robust, but the air drawn in then also gets through unfiltered into the engine and with it all the particles that can cause significant damage to the engine. As a rule, air filters made of paper are installed in the vehicle. With this filter, however, the suction power in the engine compartment is reduced somewhat. As part of a tuning, you can (have) exchange this paper filter for one made of cotton. It is installed in the original air filter housing. Cotton filters are usually stronger and more durable than paper filters. In addition, the sports air filters made of cotton can be cleaned easily and simply by yourself. This should also be done regularly, because a heavily soiled air filter reduces the oxygen supply.
If not only the air supply in the engine should be optimized, but also the sound should be intensified, then come open sports air filters for use. The filter systems in the form of a drum or a cone are attached directly to the intake area of the engine by tuners. The effects of the air supply occur immediately afterwards. An open filter expands the area from which the air is sucked in. This allows more air to enter the engine's combustion chambers, allowing for an increase in fuel combustion. In addition, there are systems that use special cooling cool the air at the same time. This cools the engine down and provides more power. Above all, the open filter is one thing: namely loud! The engine roar is significantly amplified. Above all, the sound tuning is in the foreground in this case. But does tuning with sports air filters actually increase performance? What are the advantages and disadvantages of tuning?
Pros and cons of air filter tuning
You can almost always install the sports air filter yourself. You don't necessarily need the help of a professional for this. A common assumption is that tuning is all about the performance increase goes. The common testing organizations clarify the following: An actual increase in performance of the car engine is often not at all or only barely prove. Even a moped cannot, or only slightly, increase its performance with a sports air filter. Theoretically, increasing the air supply in the engine's combustion chamber should ensure that fuel is burned. However, most engines are designed to ignite only at a very specific ratio of gas, air and fuel. This often even results in a reduction in performance. One way to fix that would be Customization of the software to the addition of fresh air.
By installing an open filter, not only fresh, but also hot air gets into the engine, as a result the temperature in the engine increases and the saturation of oxygen in the combustion chamber decreases. This phenomenon can only be mitigated by major tuning measures. Namely when the sucked air at the same time is cooled. In many cases, however, the acceptance by the TÜV, GTÜ, DEKRA and Co. then becomes a problem. A small advantage then often becomes apparent. Namely, that the combustion of oxygen starts faster because it is available faster in the combustion chamber. Mainly, tuning the air filter can ensure that the engine responds slightly better to the accelerator pedal. In addition to the lack of an increase in performance, there are other disadvantages:
- Increase in fuel consumption
- Increase in noise emissions
Tip: complete air intake systems - you install a high-quality one Cold air intake such as products from Eventuri, BMC, Arma Speed, TA Technix & Co, then it is definitely one of them noticeable increase in performance to speak. However, such systems are usually closed or partially closed and at best even equipped with an approval. They are extremely sophisticated and in some cases cost over €2.000. It is obvious that there must be a difference to a €35 sports air filter mushroom. But even these systems usually only work really effectively if the software of the engine is adapted to it.
As a rule, the increased air supply also means that more fuel is required because the ignition can only ignite correctly with a specific ratio of oxygen and fuel. As more air enters the combustion chamber, more fuel is required to start ignition. The consistent driving style However, there can also be a saving effect, since there is more power from the engine. As a rule, the subjective impression that the sports air filter contributes to the increase in performance is increased by the increased engine noise during the intake process. The engine sounds fuller and sportier than before. But especially because of the increased noise emissions, you need them individual acceptance by a qualified examiner. If the engine noise is too loud, the approval of the tuning air filter can be refused. Are no documents (ABE, Teilegutachten etc.), then this is the case with the open filter anyway. You should therefore always obtain information and advice beforehand. And you shouldn't forget that open sports air filters can sometimes also suck in larger parts, which can then lead to considerable damage to the engine. Tip: The normal case is when inserting a cotton filter no individual acceptance necessary. And you save time and money in the long run because the filters are easier to clean and more durable than normal paper filters.
Necessary permits and certificates
Will the paper filter be replaced with an easy-to-clean one Cotton filter changed, you usually do not need an additional approval by a testing organization. However, the situation is different when installing one open air filter out of. Only car accessories may be installed that have a Teilegutachten or has an ABE. You should make sure that the parts certificates are only issued by reputable and well-known testing organizations. Is the general operating permit (ABE) mandatory for the air filter? Sports air filters must save own ABE. In any case, however, a so-called individual acceptance be carried out by an approved testing organization (TÜV, DEKRA, GTÜ, etc.).
The examiner will primarily examine whether the noise intensity exceeds the limit exceeds. You can read about the permitted limit values in Part I of the registration certificate, the vehicle registration document. What applies in Germany? A noise pollution from 80 decibels should not be exceeded. The corresponding information can be found in Paragraph 49 of the Road Traffic Licensing Regulations, or StVZO for short. In the European Directive 70/157 / EEC the following was decided on February 06, 1970:
The directives set limit values for the noise level of the mechanical components and the exhaust system of the motor vehicles concerned. These limit values are between 74 dB(A) for passenger cars and 80 dB(A) for high-performance commercial vehicles.
These regulations apply to cars, vehicles for freight transport and public transport. If your tuning exceeds the allowable limits, your operating permit may be revoked until the tuning is reversed. And in addition to the noise level, the testers also check compliance with the emissions behavior. Because the increased fuel consumption can also increase exhaust emissions. Then a reclassification may be necessary. So the changes after installing a sport filter are to be checked immediately. These are then entered in the vehicle documents.
TÜV and sports air filter
If you do not register the structural measures properly, your operating license can be withdrawn, even if the tuning is actually permissible. In addition, the insurance cover can be omitted. A fine of up to 50 euros can be imposed for driving without an operating permit.
Of course, that wasn't the end of it.
