Cabin filter Nissan Sunny FB15: where is it located and how to replace it yourself

Owners Nissan Sunny in the back FB15 (2011–2017 model years) are often faced with the question: where is the cabin filter hidden in this model?

This topic is especially relevant for those who buy a used car - the previous owners do not always ensure the timely replacement of consumables.

In this article you will find exact filter layout, step-by-step instructions for replacing it, as well as tips for choosing original and analog consumables. We will analyze the nuances for different modifications Sunny FB15 (including versions with air conditioning and climate control), and we will also tell you what mistakes are most often made when replacing them yourself. If you want to save on services and do everything yourself, this guide is for you.

Where is the cabin filter located in the Nissan Sunny FB15: exact location

B Nissan Sunny FB15 cabin filter installed in the cabin under the instrument panel, on the passenger side. Specifically, it is hidden behind a decorative cover, which is located under the glove compartment, closer to the central tunnel. This is not the most convenient place, but this solution allowed engineers Nissan save space in the engine compartment.

To get to the filter, you do not need to disassemble half of the interior - just remove the plastic plug. However, there is a nuance: in versions with climate control Access may be a little difficult due to additional ductwork. In basic configurations (with a manual ventilation system) the process is simpler.

• 🔧 To access the filter no special tools are needed - just a flat-blade screwdriver (for prying off the clips).
• 🚗 B Sunny FB15 with right hand drive (for example, Japanese versions) the filter is located symmetrically - on the driver's side.
• ⚠️ On some restyled models (2015–2017), the fastening of the cover may differ - screws are used instead of clips.

If you have never changed the filter yourself, we recommend that you first inspect the area under the glove compartment in good light.

Original vs analogs: which cabin filter to choose for Sunny FB15

When choosing a cabin filter for Nissan Sunny FB15 Owners have two main options: original consumables from Nissan or analogues from third party manufacturers. The original filter has an article number 27277-4M000 (or 27277-4M00A for some markets) and costs on average 1,200–1,500 rubles. Its main advantage is guaranteed quality and perfect fit.

However, there are worthy analogues on the market that will cost less, but will not be inferior in efficiency. Here is a list of proven brands:

Brand	Article	Filter type	Approximate price, ₽	Features
Mann-Filter	CU 22003	Coal	800–1 000	High quality filtration, suitable for allergy sufferers
Bosch	1 987 429 655	Regular/charcoal	600–900	Good price-quality balance, easy to find in stores
Filtron	K 1152 A	Coal	500–700	Budget option, but does not retain fine dust as well
Sakura	CAF22003	Coal	700–900	Japanese quality, suitable for humid climates

When choosing, pay attention to filter type:

• 🔹 Regular (dusty) - traps only large dust and insects. Cheap, but ineffective against odors and bacteria.
• 🔹 Coal — absorb harmful gases (for example, exhaust) and unpleasant odors. The best choice for the city.
• 🔹 Electrostatic - rarely found for Sunny FB15, but cope best with allergens.

⚠️ Attention: Do not buy filters without packaging or with a damaged box - they could have been stored in dusty conditions and have already lost their properties. Also avoid overly cheap analogues (price below 400 ₽), as they are often made from low-quality materials.

Common mistakes when replacing the cabin filter in Sunny FB15

Even such a simple procedure as replacing the cabin filter can be ruined. Here the most common mistakesthat the owners allow Nissan Sunny FB15:

• 🔄 Incorrect filter orientation — if you mix up the direction of the arrows, the filtration efficiency will decrease by 30–40%. Always check the sign UP or AIR FLOW.
• 🛠️ Damage to the cover clips — many car owners break the fasteners when trying to remove the panel with a screwdriver. It's better to use a plastic pick or a credit card.
• 🚫 Ignoring Air Duct Cleaning — if dirt has accumulated in the system, the new filter will clog twice as quickly. It is recommended to vacuum the air ducts before installation.
• 🔧 Forgetting to check the seal — over time, the rubber gasket loses its elasticity, and gaps appear between the filter and the housing, through which unfiltered air penetrates.

Another common mistake is buying the wrong size filter. For example, some owners mistakenly take consumables from Nissan Almera N16 (article 27277-95F0A), which is similar in appearance, but does not match in height. Always check catalogs or use online parts selectors by VIN code.

What to do if the filter does not fit into place?

If the new filter does not fit into the grooves, check:

1. Correct orientation (arrows should point up).

2. The presence of foreign objects in the seat (sometimes leaves or debris remain there).

3. Size Match - Compare the old and new filters side by side.

If the problem persists, the filter housing may be deformed (for example, after an accident). In this case, the entire duct block will need to be replaced.

When to change the cabin filter: signs and frequency

The manufacturer recommends changing the cabin filter at Nissan Sunny FB15 every 15,000 km or once a year. However, in real operating conditions (especially in large cities), this interval should be reduced to 10,000 km. Here main featuresthat the filter requires replacement:

• 🌬️ Weak air flow from the deflectors even at maximum fan speed.
• 🤧 Constant fogging of windows — a dirty filter impairs air circulation.
• 🚬 Persistent unpleasant odor in a cabin that is not cleaned even after cleaning.
• 🤒 Increased allergic reactions in passengers (sneezing, itchy nose).
• 🔊 Extraneous noise when the fan is running (for example, whistling or crackling).

If you operate your vehicle in difficult conditions (dusty roads, metropolis with high levels of smog, frequent off-road driving), check the condition of the filter every 5,000 km. To do this, you don’t have to remove it - just turn on the airflow at full power and sniff: if the air has a musty or chemical smell, it’s time to change the filter.

⚠️ Attention: If in the salon appeared antifreeze smell, this may not indicate a dirty filter, but a leak in the heater core. In this case, urgent diagnostics are required - driving with such a malfunction is dangerous to health (ethylene glycol vapors are toxic).

For those who want to save money, there is alternative option — cleaning the filter using a vacuum cleaner or compressor. However, this is a temporary solution: after this procedure, the filter loses up to 60% of its efficiency, and it will still have to be replaced in the near future.
