Vehicle operation Nissan Almera the new generation (G15) requires regular maintenance, one of the key elements of which is the cleanliness of the air path. The 1.6 liter engine installed on this model is very sensitive to the quality of the mixture, and a clogged filter can cause loss of power and increased fuel consumption.
Many car owners believe that replacing this consumable is a simple procedure that does not require the intervention of a specialist. However, if incorrectly dismantled or installed non-original spare parts, the tightness of the system can be compromised, which will lead to unfiltered air entering the cylinders and premature wear of the engine.
In this article we will look in detail at how to carry out maintenance yourself, what tools you will need and what to look for when choosing a part. We will also touch on the issues of diagnosing the condition of the filter and common mistakes that beginners make when servicing Nissan Almera.
Why is timely replacement necessary and how does it affect the engine?
The air filter acts as the “lungs” of the car, cleaning the air entering the engine from dust, dirt, insects and small debris. Under Russian road conditions, especially in rural areas or during dust storms, the element becomes polluted much faster than stated in the regulations.
If you ignore the replacement, the effect of “suffocating” the motor occurs. The mixture becomes too rich because the electronic control unit ECU tries to compensate for the lack of air by increasing the fuel supply. This directly affects fuel consumption, which can increase by 10-15%.
In addition, a clogged filter creates excess resistance, causing the engine to work under increased load. Long-term operation in this mode accelerates wear of the piston group and can lead to engine overheating during intense driving.
- 🚗 Reduced dynamic characteristics of the car during acceleration.
- 🛢 Increase in fuel consumption by 10-15% in the urban cycle.
- ⚙️ Increased wear of internal engine components due to abrasive particles.
⚠️ Attention: If you notice that the engine has started to stall or the Check Engine light has come on, first check not only the spark plugs and coils, but also the condition of the air filter. Sometimes a simple replacement solves the problem without expensive diagnostics.
Selecting an original filter and high-quality analogues
In the spare parts market for Nissan Almera G15 There is a huge selection of solutions, from cheap Chinese counterfeits to certified originals. The original usually comes in a box with a logo Nissan Genuine Parts and has a catalog number, which can be checked with the dealer.
However, it is not always worth overpaying for a brand. There are proven analogue manufacturers that offer products of equal or even better quality. The main thing is to carefully check the geometry of the product and the tightness of the rubber edging to the body.
When choosing, pay attention to the density of the filter material. A filter that is too loose will not retain fine dust, and a filter that is too dense can create excessive resistance. The ideal option is a material with impregnation that improves filtration, but does not block the air flow.
- 🔍 Manufactories: Mann-Filter, Mahle, Purflux - excellent European analogues.
- 📦 Packaging: Make sure that the packaging is not wrinkled and there are no traces of moisture or oil inside.
- 🛡 Check: Inspect the rubber seal for cracks and deformations.
⚠️ Attention: Avoid purchasing filters without packaging or in damaged factory wrapping. Even minor damage to the paper corrugation can cause part of the filter element to move away from the base and enter the intake manifold.
Preparing tools and work area
The replacement procedure does not require specialized equipment or a lift. An ordinary set of tools that can be found in the trunk of any driver is sufficient. However, having free space and good lighting will speed up the work and avoid losing small parts.
You will need a Phillips screwdriver with a long blade, as the filter housing cover bolts are often located in awkward places. It is also advisable to have a flashlight to illuminate the inside of the case and check for foreign objects.
Before starting work, it is recommended to warm up the engine to operating temperature and allow it to cool for 10-15 minutes. Hot air in the engine compartment can be dangerous, but a cold engine provides better visibility and ease of working with parts.
- 🔧 Tools: Phillips screwdriver (PH2), flashlight, gloves.
- 🧹 Cleanliness: It is recommended to wipe the area around the filter housing from dust before opening.
- 📝 Recording: Write down or photograph the location of the pipes if they interfere with dismantling.

Step-by-step instructions for replacing the air filter
Open the car hood and secure it with a secure stop. Locate the air filter housing, which is located on the right side of the engine compartment (when viewed in the direction of travel) and has a characteristic black rectangular plastic box.
To access the filter, you need to unscrew the cover latches. On Nissan Almera G15 Usually metal clamps or Phillips screws are used. Loosen all the latches, but do not remove them completely to avoid losing them.
Carefully lift the housing cover. Be careful as condensation or small debris may accumulate inside. Remove the old filter without dropping it inside the housing, so as not to spill dirt on the mass air flow sensor (MAF).
☑️ Preparation for replacement
⚠️ Attention: If you see a lot of dust or leaves inside the housing when you remove the cover, be sure to clean it before installing a new filter. Use compressed air or a soft cloth, but do not wash the case with water.
Before installing a new element, carefully inspect the seat. The rubber seal on the new filter should lie flat, without distortion. Install the filter into the housing, making sure that it fits snugly against the walls around the entire perimeter.
Close the cover and tighten the fasteners. Do not use excessive force to avoid stripping threads or breaking plastic fasteners. Make sure the lid fits tightly and has no gaps.
