Car engine intake system Nissan Murano the third generation (Z52 body) requires special attention, since this is where the process of forming the air-fuel mixture begins. The quality of incoming air directly affects the power of the power unit, fuel consumption and turbine life. The element responsible for cleaning is a consumable item that requires regular diagnostics and timely replacement.
Many crossover owners neglect this maintenance item, believing that the filter lasts forever. However, in the conditions of Russian roads with their dust and reagents, the resource of the element is reduced significantly. Ignoring the condition of the air filter can lead to serious consequences for the engine VQ35DE or VQ35HR, which are installed on this model.
Design features of the Murano Z52 intake system
Unlike previous generations, the model Nissan Murano Z52 engineers reconfigured the air intake and filter housing. The air cleaner is housed in a plastic housing, which is integrated into the overall intake system, which requires careful dismantling. The design is designed for the high volume of air flow required to operate a displacement engine.
The cleaning efficiency is ensured not only by the material of the filter element, but also by the tightness of the housing itself. Any cracks in the plastic casing or a loose lid allow untreated air to enter the combustion chambers. This phenomenon, known as “suction,” causes accelerated wear of the cylinder-piston group and coking of the valves.
A special feature of this body is that the filter is located in a hard-to-reach place, which often forces owners to contact service centers. However, if you have a minimum set of tools, the replacement can be done independently in a few minutes, which significantly saves the owner’s budget.
Criteria for selecting original and analog elements
When selecting consumables, it is important to focus not only on appearance, but also on technical characteristics. Original from Nissan has its own unique catalog number, which guarantees compliance with factory tolerances for density and filter surface area. The use of low-quality counterfeits can lead to deformation of the element under air pressure.
There are many proven analogue manufacturers, such as Victor Reinz, Mann-Filter or Sakura. These brands offer products that often exceed the performance of standard factory parts. The main condition is to check the geometry and tightness of the rubber seals.
- ✅ Original - provides maximum compatibility, but is often overpriced and carries the risk of buying a fake.
- ✅ High-quality analogue - optimal price-quality ratio, often used in pre-sale preparation of cars.
- ✅ Sports filters — require impregnation with oils and regular washing, not suitable for everyday use in the city.
You should not save on this part, since the cost of replacement is not comparable to the cost of engine repair. The catalog number of the original filter for the Nissan Murano Z52 is 16546-1HC0A, which is universal for most body modifications. Before purchasing, always check the markings on the packaging with the data in the service book of your car.
Diagnosis of condition and signs of contamination
You can understand that the filter has become unusable by indirect signs of engine operation. When heavily polluted, the engine begins to “choke”, losing power during acceleration. There may also be an increase in fuel consumption as the electronics try to compensate for the lack of air by changing the composition of the mixture.
Visual inspection is the most reliable inspection method. If the filter element is covered with a layer of dense dust, soot or traces of insects, it must be replaced immediately. The color of the original paper is usually light gray or yellowish; severe darkening indicates a critical condition.
⚠️ Attention: A dirty filter can lead to engine overheating in the summer due to impaired air circulation through the radiator, as part of the flow is blocked.
Sometimes owners try to extend the life of the filter by blowing it with compressed air. This is strictly not recommended, as dust microparticles become even more clogged in the pores of the material, and the structure of the paper fold may be damaged. After purging, the cleaning efficiency drops significantly, and the risk of engine damage increases.

Step-by-step instructions for replacing the filter
The replacement process does not require sophisticated equipment, but requires care so as not to damage the fragile plastic of the case. Before starting work, you must open the hood and lock it in the upper position. You will need a Phillips screwdriver and maybe a 10mm socket to unscrew the clamps.
First of all, you need to find the air filter housing, which is located in the front of the engine compartment. Disconnect the mass air flow sensor (MAF) connector if it is installed directly on the housing to avoid damaging it when removing the cover. Carefully unscrew all fasteners around the perimeter of the cover.
☑️ Preparation for replacement
Remove the housing cover and remove the old element. Pay attention to its position and installation direction so that the new filter fits correctly. Clean the interior of the case from debris and dust using a soft cloth or vacuum cleaner. It is important not to leave foreign objects inside.
Install the new filter, making sure that the rubber seal fits snugly into the housing. Close the lid and tighten the fasteners, but be careful not to over-tighten the plastic. Return the sensor connector to its place. Start the engine and check for any abnormal air intake noise.
The nuances of working with the mass air flow sensor
The mass air flow sensor is very sensitive to dirt and mechanical damage. When disconnecting the connector, be careful not to break the latch. If the sensor is dirty, it can be cleaned with a special aerosol, but this must be done extremely carefully, without touching the sensitive elements with your fingers or cloth.
The influence of filter quality on fuel consumption and the environment
The condition of the air filter directly correlates with the efficiency of the car. When there is not enough air, the engine control computer is forced to adjust the ignition timing and mixture composition, which leads to suboptimal fuel combustion. This can increase consumption by 5-10% in the urban cycle.
Also, a clean filter plays an important role in the environmental friendliness of exhaust gases. Incomplete combustion of fuel due to lack of air leads to increased levels of carbon monoxide and hydrocarbons in the exhaust. Regular replacement of the element helps meet environmental standards and reduces the load on the catalyst.
- 🌱 Savings — a clean filter provides the nominal fuel consumption declared by the manufacturer.
- 🌱 Ecology — the toxicity of exhaust gases is reduced, the service life of the catalytic converter is extended.
- 🌱 Power — the engine develops full power, providing confident acceleration.
Don't wait until the filter is completely clogged to replace it. Scheduled replacement is recommended every 15,000 kilometers or once a year, depending on operating conditions. In conditions of dusty roads or frequent off-road driving, the interval should be reduced to 7-10 thousand kilometers.
Before purchasing a new filter, compare it with the old one by placing them side by side. Pay attention to the height of the folds and the quality of the rubber edging - this will help you avoid buying a low-quality analogue.
Common mistakes when servicing the intake system
One of the most common mistakes is ignoring the condition of the filter housing itself. Even if you installed a new element, but there is a crack in the body, there will be no effect. Air will be sucked past the filter, carrying dirt and sand directly into the cylinders.
Another mistake is using sealants or glue to fill gaps in the housing. This is unacceptable, as sealant can get inside the system and cause blockage of channels or damage to sensors. If the housing is cracked, it must be replaced entirely or use special repair kits designed for plastic.
⚠️ Caution: Never use all-purpose sealants to repair the air filter housing, as chemical vapors may enter the engine and cause it to seize.
It is also worth mentioning the error associated with incorrect installation of the filter. If it is inserted at an angle or skewed, the rubber seal will not be able to provide a tight seal. This will lead to vibration and noise during engine operation, as well as the entry of unfiltered air.
