Nissan Murano Z51 Air Filter Replacement: Complete Guide

Timely maintenance of the engine intake system is a critical aspect of vehicle operation. Nissan Murano second generation (Z51 body). A dirty filtration element not only reduces the power of the unit, but can also lead to increased fuel consumption and accelerated wear of the piston group.

Many crossover owners Nissan Murano Z51 They put off a visit to the service, believing that replacing the filter is a purely procedural detail. However, the reality is that clean air flow directly affects the combustion efficiency of the fuel mixture and, as a result, the acceleration dynamics of your SUV.

Why is replacing the air filter on your Nissan Murano Z51 so important?

Series engines VQ35DE, installed on Nissan Murano, are extremely sensitive to the quality of incoming air. In an urban environment with a high level of dust, a standard filter quickly loses its properties. If you ignore routine maintenance, the system intake starts to work abnormally.

Small dust particles penetrating through a clogged element act as an abrasive. This leads to premature wear of the cylinder walls and piston rings. In addition, the engine is forced to spend more energy to overcome the resistance of a clogged cartridge, which inevitably affects fuel consumption.

Pay attention to the characteristic signs indicating the need for urgent replacement:

• 🚗 Deterioration of acceleration dynamics and “sluggish” gas pedal response
• ⛽ Unreasonable increase in gasoline consumption
• 🔊 Changing the sound of the engine at idle
• 💨 Black smoke appears from the exhaust pipe

Don't wait for the indicator to light up Check Engine. Preventative replacement is much cheaper than major engine repairs. Regularly checking the condition of the filter should be part of your standard vehicle maintenance routine.

⚠️ Attention: Using low-quality analogues can damage the mass air flow sensor (MAF), the replacement of which is very expensive Nissan Murano Z51.

Selecting consumables: Original or analogue?

There are many offers on the spare parts market, and choosing the right option for Nissan Murano Z51 it can be difficult. The original filter from the manufacturer provides ideal filtration and meets all factory tolerances. However, its price often exceeds the cost of high-quality analogues several times.

Quality replacements from trusted brands can offer comparable filtration performance at a more affordable price. It is important to pay attention to the density of the filter material and the tightness of the sealing gum. A poor fit will result in dirty air entering the engine bypassing the filter.

Preparation for replacement and necessary tools

Procedure for replacing the air filter Nissan Murano Z51 does not require complex specialized equipment. You will need a minimum set of tools, which are found in almost any garage or home. The main condition is the availability of free space under the hood and clean hands.

To successfully complete the job, prepare the following items:

• 🔧 Phillips screwdriver (PH2 or PH3) for unscrewing clamps and screws
• 🧤 Gloves to protect hands from dirt and oil
• 📦 New air filter
• 🧽 A rag for wiping the filter housing
• 🔦 Flashlight (if work is carried out at dusk)

Before starting work, it is recommended to turn off the engine and allow it to cool slightly. This will protect you from accidental burns from hot elements. cooling systems or exhaust manifold. Open the hood and securely fix it using the special stop.

Step-by-step instructions for replacing the filter

Find the air filter housing on Nissan Murano Z51 It’s not difficult: it’s a large plastic box located on the left side of the engine compartment (if you look in the direction of travel). It is connected to the throttle valve by a large corrugated pipe. The whole job will take no more than 15 minutes.

First you need to loosen the clamp that tightens the corrugation at the exit from the housing. Use a Phillips screwdriver to turn the clamp screw counterclockwise. There is no need to unscrew it completely, just loosen it enough so that the pipe can be removed freely.

Next we move on to attaching the body itself. The top cover is held on by several screws and latches.

• 🔩 Unscrew all the screws around the perimeter of the top cover
• 🔓 Release the plastic clips if present
• 📤 Carefully lift the housing cover up
• 🗑️ Remove the old filter, being careful not to spill dirt inside

Inspect the interior of the housing. If dust or leaves have accumulated there, carefully remove them with a dry cloth. No debris should get inside the engine. Make sure that the sealing rubber on the lid is not damaged and fits tightly.

Common mistakes when replacing

The most common mistake is 忘记 (forgetting) to install the filter exactly in the grooves. This leads to the suction of unfiltered air and errors in the mass air flow sensor. It is also important not to overtighten the cover screws, as the plastic may crack.

Install the new filter into the housing, making sure it fits snugly against the seal. Close the cover and tighten the screws. Place the pipe back onto the outlet flange and tighten the clamp until it stops. Check that all connections are secure.

Maintenance considerations for turbocharged systems (if applicable)

Although most Nissan Murano Z51 are equipped with naturally aspirated V6 engines, there are modifications or tuning solutions with turbocharging. In such systems, the requirements for air filtration are much higher. The turbine operates at enormous speeds and is extremely sensitive to the quality of lubricant and air.

For turbocharged versions, it is critical to use filters with a high cleaning class. A clogged filter creates inlet resistance, which can lead to overheating of the turbocharger and a decrease in its service life. In such cases, it is recommended to change the filter more often than prescribed by the regulations.

If you operate your vehicle in dusty conditions, the replacement interval should be reduced from the recommended 30,000 km to 15,000 km. This is especially true for turbocharged engines, where the load on the intake system is maximum.

Frequently asked questions from Nissan Murano Z51 owners

Crossover owners often ask questions regarding the specifics of maintenance. Let's look at the most popular of them to dispel doubts and prevent mistakes when servicing yourself.

Can I wash and use the old filter?

For paper filters installed in Nissan Murano Z51, washing is strictly prohibited. Water destroys the fiber structure, and oil (if used for impregnation) can clog pores. A washed filter loses its properties and allows dirt to pass through. Use only a new part.

How often should you change your air filter?

Official regulations Nissan recommends replacement every 30,000 km or every 2 years. However, if you drive on dirt roads or in very dusty conditions in the city, it is better to reduce the interval to 15,000 - 20,000 km. Regular visual inspection will help determine the condition.

What happens if you forget to put the filter on?

Driving without a filter is a guaranteed entry of abrasive particles into the engine. This will lead to rapid wear of the cylinder-piston group, a drop in compression and, ultimately, the need for major repairs. Engine VQ35 quite hardy, but without a filter it will not live very long.

Do I need to reset errors after replacing the filter?

Usually this is not necessary. The vehicle's ECU automatically adapts to new intake conditions over several engine cycles. If the error P0171 or P0172 (lean/rich mixture) was burning due to a dirty filter, it should go away after replacement and a few trips. If the error persists, the problem may be deeper.

⚠️ Warning: Never use compressed air to blow through the paper filter. This can damage the structure of the material, creating microcracks through which dust can pass.

Regular intake system maintenance is the key to a long life for your engine. Nissan Murano. Simple and quick filter replacement saves money on repairs and keeps your car in great shape. Do not neglect these procedures, and your crossover will delight you with reliability and power.
