Owners Nissan Almera G15 generations often face the need for routine vehicle maintenance, and one of the most important procedures is replacing the air filter. Many car owners mistakenly believe that access to the filter element is hidden deep in the engine compartment or requires the removal of complex panels. In fact, the designers Nissan We tried to simplify this process as much as possible, making it accessible even to beginners without special skills.
Correct location air filter on Nissan Almera G15 provides quick replacement, which saves time and money in service. In this article, we will look in detail at where exactly this unit is located, what tools are needed for the job, and how to avoid common mistakes during maintenance. Knowing the exact location of the element is the first step to extending the life of your car's engine.
General arrangement and design of the air path
On the model Nissan Almera G15, equipped with a 1.6 liter engine (HR16DE series), the air supply system is quite simple and intuitive. The air filter is housed in a special plastic housing, which is located on the right side of the engine compartment when looking at the car from the front. This housing is connected to the throttle valve by a flexible pipe through which purified air flows directly into the engine.
The filter housing is made of durable plastic and consists of two parts: the lower base and the upper cover. Fastening is carried out using special metal clamps or screws, depending on the year of manufacture and vehicle equipment. You don't have to disassemble half the engine compartment to get to filter element. It is enough to unscrew the fasteners and lift the upper part of the case.
It is important to note that the body is located in an area that is relatively well lit when the hood is opened. This allows you to easily assess the condition of the filter and, if necessary, quickly replace it. However, you should be careful, as there may be hot elements of the cooling system or exhaust nearby if the engine has recently been running. It is recommended to carry out inspection and replacement on a cold engine.
Necessary tools and preparation for work
To replace it yourself air filter on Nissan Almera G15, you will need a minimum set of tools. In most cases, a regular Phillips screwdriver is sufficient, since the housing cover is secured with slotted screws. Sometimes there are models that use clamps that can be opened by hand or using a flat-head screwdriver to pry them off.
Before starting work, it is necessary to prepare a new product. Original filter for Nissan has catalog number 16546-00QAB or its equivalents from third-party manufacturers, such as Corteco, MAHLE or Pilenga. Do not try to use filters from other models, as the size and shape of the sealing rubber may not match, which will lead to the suction of unpurified air.

Step-by-step instructions for accessing the filter
The process of accessing the filter element on Nissan Almera G15 consists of several simple steps. First, find a plastic box that looks like a rectangular box with a pipe going towards the engine. It is located closer to the right wing mudguard. Inspect the top cover of the case and find the attachment points.
Depending on the modification, the cover can be secured with four screws or two metal clips. If there are screws, use a Phillips screwdriver to unscrew them counterclockwise. If there are clips, carefully pry them up with a screwdriver or press the clips and bend them upward. The main thing is not to use excessive force so as not to break the plastic retainer.
Once the fasteners are loosened, carefully lift the top housing cover. Be careful as the cover may be connected to the bottom by a flexible wire from the mass air flow sensor (MAF) if it is built into the housing. In this case, do not pull the cover sharply to avoid damaging the sensor connector. Open the cover at an angle sufficient to remove the old filter.
☑️ Access to the filter
Inspecting and removing the old element
Remove the old filter from the housing and carefully inspect its condition. If you see that the filter material is heavily soiled, covered with oil or has mechanical damage, replacement is required. A clogged filter restricts air flow, resulting in reduced engine power and increased fuel consumption. On Nissan Almera This may manifest itself as a "dull" gas pedal.
Pay special attention to the inside of the case. Often leaves, insects or debris get there along with the old filter. Before installing a new element, you must thoroughly clean the internal cavity of the housing. Use compressed air or simply wipe the surface with a clean rag. The presence of dirt inside the housing can cause it to enter the engine along with the new filter.
If you are using a reusable sports filter (which is not recommended for standard use), it must be washed and soaked in special oil. However, for normal operation Nissan Almera G15 It is better to use disposable paper filters, which provide a better degree of purification and a predictable resource.
⚠️ Caution: Do not attempt to blow out the paper filter with compressed air for reuse. This disrupts the fiber structure and reduces filtration efficiency, which can lead to wear of the cylinder-piston group.
Why can't you wash a paper filter?
The paper filter has microscopic pores that become clogged with dust particles. When washed with water or a solvent, the fiber structure is destroyed, the pores expand, and the filter no longer retains fine dust. In addition, water may remain inside, causing corrosion or mold growth.
Installing a new filter and checking for leaks
Installation of a new filter must be carried out in compliance with all safety precautions. Insert the new element into the bottom of the housing so that it fits snugly around the perimeter. Make sure the rubber seal is not twisted or misaligned. This is critical to prevent unfiltered air from being drawn past the filter.
Lower the top housing cover into place. If you had screws, use a Phillips screwdriver to tighten them until they are tight, but do not overtighten them to avoid stripping the threads in the plastic. If clamps were used, make sure that they click into place and that the lid is seated tightly over the entire area. Any gaps between the cover and the base of the housing are unacceptable.
After assembly, perform a visual inspection. The pipe leading from the body to the throttle must be securely secured with clamps. Check for tools or foreign objects in the engine compartment. Start the engine and listen to the work. If you hear a whistle or hiss of air, it means that the seal has been broken somewhere and the assembly needs to be reassembled.
Before tightening the screws, check that the rubber seal around the perimeter of the filter lies flat. Even a slight misalignment can lead to dirty air being sucked in and contaminating the engine.
Replacement frequency and selection of a quality filter
The manufacturer recommends changing the air filter to Nissan Almera G15 every 15,000 - 30,000 kilometers, depending on operating conditions. If you often drive on dusty roads or in city conditions with high gas pollution, the replacement interval should be reduced to 10,000 - 15,000 kilometers. Regularly checking the condition of the filter at every oil change will help avoid engine problems.
Filter selection is an important issue. Original filters Nissan They have high paper quality and a tight fit, but can be expensive. Alternative brands such as MAHLE or Blue Print, offer excellent value for money. Avoid buying cheap fakes from unknown manufacturers, as their filter material may fall apart under the air flow.
| Filter type | Benefits | Disadvantages | Recommended interval |
|---|---|---|---|
| Original (Nissan) | Perfect fit, high quality | High price | 30,000 km |
| Premium analogues (MAHLE, Corteco) | Good quality, affordable price | Less selection available | 20,000 - 25,000 km |
| Budget analogues | Low cost | Risk of low quality, poor fit | 10,000 - 15,000 km |
| Sports (oil) | Flow modification, reusability | Risk of contamination of the air flow sensor, difficulty of maintenance | As needed |
⚠️ Attention: Using a low-quality filter can lead to failure of the mass air flow sensor (MAF), the replacement of which costs much more than the filter itself.
Regularly replacing the air filter is the easiest and cheapest way to maintain engine power and reduce fuel consumption on your Nissan Almera G15.
Typical maintenance errors
Many car owners make mistakes when replacing the filter, which can lead to serious consequences. One of the most common mistakes is installing a filter without checking the leaks. If the housing cover is not completely closed or the clamps are not latched, the motor will begin to draw in dirty air directly, bypassing the filter.
Another mistake is ignoring the condition of the case. If moisture or dirt has accumulated in the housing, the new filter will quickly become dirty and lose its properties. Always clean the interior before installing a new element. Also, you should not try to “save” and blow out the old filter - this is useless for paper products.
Some owners try to install the filter in the wrong orientation. Make sure that the filter element fits smoothly and does not require any force. If the filter does not fit, do not use force - check if it is the wrong model and if you removed the old element correctly. Improper installation of the filter can result in it getting into the engine and causing major repairs.
What should I do if the filter does not fit into the housing?
Check whether the housing or the filter itself is deformed. Make sure the rubber seal is not pulled out. If the filter is from another car, it may not fit. Always check the part number.
