Air filter – Buying Guide, Opinions and Analysis
The air filter of a car or motorcycle is one of the elements that allows a vehicle to run properly, therefore, its maintenance or timely replacement depends on the optimal performance of the engine and its useful life. If you have decided to purchase an air filter, the Ramair Filters CC-296-UNI stands out among the most favorable options, since it has reducing rings, is made of foam and its inner cage is made of stainless steel. Another alternative that you can consider is the K&N 33-2763 model , a square-shaped flat filter, capable of contributing 50% more performance, which is reusable.
Air filters are essential parts in every vehicle, as they act as a barrier that prevents the entry of polluting particles that could impair the power and performance of the engine. To guarantee optimal vehicle performance and avoid subsequent failures related to this cause, it is important to know how to choose a suitable product. If you don’t know how to choose it, we recommend that you analyze this guide to buy the best air filter.
There are air filters suitable to adapt to a wide variety of vehicle models, so if you want to find a suitable one for your car or motorcycle, the most prudent thing would be to make a comparison of air filters that includes those of greatest interest, to evaluate its characteristics and determine if it would be appropriate, depending on the model.
Some of these parts are designed exclusively for a few models of cars and motorcycles of some brands, so it would be convenient to consult the list of compatible vehicles, according to the make, model, year and type of engine. However, there are also other air filters whose use can be universal, which means that they can be adapted to any vehicle.
However, to have greater security, it is more advisable to orient yourself by the exact measurements of these parts, to compare with what is needed and choose based on it.
Manufacture and type
Among the wide variety of air filters available in the current market, they can be obtained from different materials of manufacture. Although they all claim to achieve the same task, there are some reasons that justify its usefulness and that could be more convenient for some than for others. This is also one of the characteristics that tends to influence when estimating how much an air filter costs.
These pieces, in general, are usually presented in cotton, paper or foam. Cotton is more used for reusable air filters, as this material can be washed more frequently, although, in some cases, it may be necessary to grease them after cleaning, in order to retain dry particles.
The paper ones, meanwhile, are one of the most used, being disposable, efficient and economical. Meanwhile, the foam ones, due to the porosity of their surface, allow a greater quantity of air to pass through and retain more waste.
Another of the most important aspects that should be taken into account, when choosing, is whether you want to have a disposable air filter or a reusable one would be preferable. Disposable air filters are designed to be replaced between 16,000 and 48,000 km, as this may vary by brand.
The reusable ones are considered as high performance, since they do not require cleaning and maintenance, until after having traveled between 48,000 and 80,000 km.
When it comes to choosing an economical air filter, disposable ones are cheaper, but they require changing more frequently, which in the long term could represent a greater investment.
Reusable ones have a higher cost initially. However, afterwards they save money because, with proper maintenance, one could only last longer. However, you have to be careful and make sure that its filtration capacity is optimal and justifies its cost.
The different types of air filters come in varied designs that make them useful and adaptable for use with certain vehicle models. Among these, the conical-shaped filters stand out, a design that implies a greater volume of air in the intake system and usually produces adequate noise in the engine.
There are also the circular ones, more common in older and carbureted vehicles. On the other hand, there are the rectangular ones, which are the most used in more recent generation vehicle models, which usually travel on all roads. Among these, there are models whose installation can be done in a very simple way and with few tools.
Some air filters have an exclusive size and design, intended to suit specific vehicle models of some brands. However, there are also some that incorporate a set of rings of different sizes, which fit inside the neck of the filter and function as reducers so that it can adapt to intake pipes of different diameters.
Some models of conical air filters are presented in kits that incorporate these adapter rings in up to 5 different sizes, with measurements ranging from 60 mm to 101 mm, and there are others with exact measurements of 70 mm, 76, 85 and 90 mm .
Frequently asked questions
Q1: How to install an air filter?
The installation of an air filter may vary depending on the type of filter and its brand, as each model has precise instructions and recommendations. However, in general, it is a quick and easy procedure to perform. To do this, you must locate, under the hood, on the engine or to the side, the air filter housing, which must have a protruding hose.
The box must be opened and the old filter removed, which may require the use of some tools to remove the bolts, nuts and clamps. To continue, you must open the housing, remove the fasteners, remove the top of the housing, and finally remove the air filter.
To continue, the new filter must be placed inside the box, making sure that the rubber ring is facing upwards. Finally, the casing must be replaced and the fasteners secured.
Q2: How to clean the air filter?
To clean the air filter, the first thing to do is locate the box where it is located and remove it from there. To begin cleaning, it is necessary to shake it carefully, so that it removes the thickest remains of accumulated dirt.
Cleaning can be completed with the use of a vacuum cleaner. In the same way, it is convenient to vacuum the inside of the box where the filter is placed. To remove more impurities in this area, it can be wiped with a cloth or paper on the surfaces, without rubbing.
Q3: What if the air filter is dirty?
A dirty air filter has a direct effect on the performance of the engine, as this accumulation of dirt would reduce its power and, therefore, would mean a higher fuel consumption, as it had to be forced more to run. This, in addition, would influence the vehicle to produce and emit a greater amount of pollution.
The failure of the engine due to a blockage by a dirty filter also has negative effects on other mechanical parts that, together, could represent worse damage, which could seriously compromise the useful life of the vehicle, since the car would be more prone to suffer breakdowns and breakdowns more frequently.
Q4: Every how many kilometers is the air filter changed?
The air filter should be changed at least every 15,000 kilometers or once a year. However, some environmental and weather conditions are likely to influence the performance of the air filter, so it may be necessary to change it ahead of time or meet the estimated kilometer limit.
Q5: Where is the air filter on a motorcycle?
The location of the air filter on a motorcycle can vary, as this generally depends on the type of motorcycle. On some models, the air filter may be located at the bottom of the motorcycle’s fuel tank. Meanwhile, on some newer motorcycle models, the area where the air filter is located is on the side.
Q6: Which is better, a plastic or metal frame air filter?
These two types of filters have a similar function, which could be useful in either case. However, it is something that will depend directly on the choice and preferences of each user, who may have their own reasons for choosing one type or another.
However, although both are built in materials that must guarantee stability and resistance, air filters with a metal frame suppose greater resistance and durability, since this is a stainless material stronger than plastic and also has the property of being more tolerant to The high temperatures.
Q7: What is a high flow air filter for?
A high flow air filter is used to keep out more pollutant dust residues, solid particles and oxygen molecules, in order to offer greater protection to the engine and its parts.
These filters have the ability to allow a greater flow of clean, fresh air to enter the engine. This air, free of impurities, favors greater efficiency in combustion. Thus, the fuel obtains the ability to supply a greater force to the vehicle, which translates into an increase in the engine power and, therefore, could improve and increase its performance up to 80,000 kilometers.
