How to replace spark plugs on a Nissan Note: a detailed guide with photos and videos

Replacing spark plugs with Nissan Note - a procedure that many owners put off until the last minute, until the engine begins to “triple” or fuel consumption increases by 10-15%. Meanwhile, timely replacement of these “small but important” parts saves money on repairing ignition coils, lambda probes and even the catalyst. In this article we will analyze which spark plugs are suitable for different Note engines (including rare versions with turbine), how to change them without errors, and why even “original” spare parts from a dealer can fail.

We analyzed owner reviews Nissan Note E11 (2004–2012) and E12 (2012–2020), studied manuals and service bulletins to collect up-to-date information. There is no “water” here - only specific data on article numbers, tightening torques and typical problemsencountered during replacement. For example, did you know that on the engine HR16DE If you dismantle the spark plugs carelessly, you can damage the threads in the block head, and the cost of repairing such an oversight can reach 50,000 rubles?

Which spark plugs are suitable for Nissan Note: compatibility table

Selection of candles for Nissan Note depends on the type of engine, year of manufacture and even the region of operation (for example, for cold climates “hot” spark plugs with a lower heat rating are recommended). Below is the current compatibility table for all modifications, including rare turbocharged versions.

Engine	Years of manufacture	Original article	Analogues (NGK, Denso, Bosch)	Gap, mm	Tightening torque, Nm
HR12DE (1.2)	2004–2012	22401-JM00A	NGK IFR6A11, Denso FK16HR11, Bosch FR7DPX	1.1	20–25
HR15DE (1.5)	2012–2020	22401-4M50A	NGK IFR6T11, Denso FK16HR11, Bosch FR7DPX	1.0–1.1	20–25
HR16DE (1.6)	2006–2020	22401-4M51A	NGK IFR6A11, Denso IXUH22I, Bosch FR7DPX	1.0	20–25
HR12DDR (1.2 Turbo)	2013–2020	22401-4M52A	NGK 97156, Denso IXEH22TT	0.9	18–22

Important! On engines HR16DE And HR12DDR (turbo) are used iridium spark plugs with an increased resource (up to 100,000 km). Installing regular nickel ones instead is a mistake that will lead to misfires after 20–30 thousand km. Also note gap between electrodes: for turbocharged engines it is smaller (0.9 mm versus 1.1 mm) and must be checked with a feeler gauge before installation.

If you buy analogues, avoid fakes! For example, “left” NGKs are often found on the market IFR6A11 with a thick central electrode - such candles quickly become overgrown with carbon deposits. Check the packaging for the presence of a hologram and check with NGK official website.

When to change spark plugs: signs of wear and regulations

Official regulations Nissan requires replacement of spark plugs every 30,000 km for nickel and 100,000 km for iridium. However, in practice, these periods are often reduced due to low-quality fuel, driving short distances (when the engine does not warm up completely) or the use of counterfeit oils. Here 5 signsthat it's time to change the spark plugs immediately:

• 🔥 Engine tripping - especially noticeable at idle or during acceleration. Often accompanied by an error P0300 (multi-cylinder misfires).
• ⛽ Increased fuel consumption - if consumption increases by 1-2 liters for no apparent reason, the spark plugs may be to blame.
• 🚗 Dips during acceleration — the engine “stalls” when you press the gas, especially at low speeds.
• 🔊 Popping sounds in the exhaust system - a sign that the fuel burns out already in the outlet due to a weak spark.
• 💡 Check Engine - errors P0301–P0304 (misfires in a specific cylinder) are almost always associated with spark plugs or coils.

A critical mistake many owners make: neglecting to replace spark plugs before symptoms appear. On engines HR12DE And HR15DE worn spark plugs lead to overloading of ignition coils, which cost from 8,000 rubles apiece. And on a turbocharged HR12DDR A bad spark can cause detonation and damage to the pistons.

If you are buying used Nissan Note, be sure to check the condition of the spark plugs! You can tell a lot about the engine by their appearance:

• 🔴 Black soot — rich mixture (problems with mass air flow sensor, lambda probe or injectors).
• ⚪ White coating - lean mixture or overheating (risk of valve burnout!).
• 🟠 Red plaque - a sign of the use of additives with iron or manganese (harmful for the catalyst).
• 🟤 Oil soot — wear of oil seals or piston rings.

Preparing for replacement: tools and safety precautions

To replace spark plugs Nissan Note you will need a minimum set of tools, but there are several critical nuanceswhich are often forgotten. For example, on engines HR16DE The spark plug wells are deep, and without a magnetic holder or rubber seal on the head of the spark plug wrench, you risk dropping the spark plug into the engine compartment (and getting it out of there is a separate headache).

Here is a complete list of tools and materials:

• 🔧 Candle key with magnetic or rubber insert (size 16 mm for most engines).
• 🔩 Extension and ratchet - You can’t get to the wells without them.
• 🛠️ Torque wrench — so as not to overtighten the spark plugs (risk of thread breakage!).
• 🧴 Penetrating lubricant (For example, WD-40) - if the candles are “stuck”.
• 🧤 Gloves and rags — wells are often dirty, and your hands get dirty with oil.
• 🔋 Gap gauge - even with new spark plugs the gap may “go away”.

Security measures:

1. Work only for cold engine — when hot, the aluminum block head expands, and there is a risk of damaging the threads.
2. Disable negative battery terminalto avoid short circuits when working with high-voltage wires.
3. Do not use extensions with hinges - they can break in the well.

What to do if a candle breaks off in a well?

If the central electrode of the spark plug remains in the block head, do not try to remove it yourself! Use a special extractor (for example, Lisle 65600) or contact service. Attempts to unscrew the fragment with pliers almost always end in damage to the thread and repair of the block head (from 30,000 rubles).

Step-by-step instructions for replacing spark plugs on a Nissan Note

The process of replacing spark plugs Nissan Note takes from 30 minutes to 1.5 hours depending on experience and access to wells. The most difficult option is the engine HR16DE, where the wells are deep and it is necessary to remove the intake manifold (on some modifications). Below are universal instructions suitable for all motors. Note.

Step 1. Dismantling old spark plugs

1. Remove decorative engine cover (it is secured with latches or bolts).
2. Disconnect ignition coil connectors (press the lock and pull up).
3. Unscrew the coil mounting bolts (usually 10 mm) and carefully remove them. Don't pull the wires!
4. Blow out the spark plug wells compressed airto prevent dirt from getting into the cylinders.
5. Insert the spark plug wrench with extension and unscrew the spark plugs counterclockwise.

Step 2. Installing new spark plugs

1. Check the gap on new spark plugs (should match the table above).
2. Apply candle threads thin layer of graphite grease (For example, Molykote G-4500) - this will make future replacement easier.
3. Carefully screw in the candles by handso as not to distort the thread.
4. Tighten with a torque wrench to 20–25 Nm (for HR12DDR - 18–22 Nm).
5. Install the ignition coils in reverse order, making sure the connectors are seated until they click into place.

Step 3. Checking the work

• Connect the battery and start the engine.
• Listen to the idle speed - there should be no vibrations or misfires.
• Check no errors via a diagnostic scanner (for example, ELM327).

⚠️ Attention! On Nissan Note with engine HR12DDR (turbo) after replacing spark plugs necessarily You need to reset the misfire counter in the ECU. Otherwise, the engine may go into emergency mode. To do this, use the diagnostic adapter and the program Nissan DataScan.

Typical mistakes when replacing spark plugs and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing candles with Nissan Note, which cost a hefty sum. Here TOP-5 most common jambs and how to prevent them:

• 🔧 Re-upholstery of candles - leads to damage to the threads in the block head. Always use a torque wrench! The maximum torque is 25 Nm.
• 🧲 Dirt getting into the cylinders — if you do not blow out the wells before unscrewing the spark plugs, sand or dust will enter the combustion chamber and act as an abrasive, accelerating wear of the piston group.
• ⚡ Using incompatible candles - for example, installing “cold” spark plugs (with a high heat rating) on the engine HR12DDR leads to detonation.
• 🔩 Damage to the ignition coil insulator — if during dismantling you pull on the wire rather than the housing, you can tear the insulation, which will cause current leakage.
• 🔥 Ignoring oil deposits — if there is oil on the spark plugs, this is a sign of problems with the valve stem seals. Simply replacing the spark plugs will not solve the problem - the cylinder head needs to be repaired.

One more non-obvious error - use copper lubricants on the candle threads. Copper has a high melting point, and when heated, the spark plug can “stick” to the block head. The correct option is graphite grease or special compositions for candles (for example, Permatex 24110).

What to do if after replacing the spark plugs the engine stalls?

1. Check coil connection order — they are easy to confuse (there is usually a cylinder numbering on the cylinder head cover).

2. Measure compression - if there is low compression in the cylinder, the spark plug will be constantly filled with fuel.

3. Check ignition coil condition - they often fail at the same time as the spark plugs.

Replacement cost: prices for spare parts and service work

Cost of replacing spark plugs Nissan Note depends on engine type, region and parts selected. Below are the current prices for 2026 (for Moscow and the Moscow region).

Expense item	Price, ₽	Notes
Spark plugs (set of 4 pcs.)	1 200–4 500	Original — ~3,500 ₽, NGK/Denso — 1,200–2,500 ₽, Bosch — 1,500–3,000 ₽.
Work in the service	800–2 000	Cost is higher on engines HR16DE due to difficult access.
Penetrating Lubricant (WD-40)	200–400	It will be needed if the candles are stuck.
Graphite grease	150–300	For processing the threads of new spark plugs.
Diagnostics after replacement	500–1 000	Recommended for resetting errors and checking misfires.

If you decide to change the spark plugs yourself, savings will be 800–2,000 rubles (cost of work in the service). However, please note that on engines HR16DE And HR12DDR access to candles is difficult, and without experience you can spend 3-4 hours instead of 30 minutes.

⚠️ Attention! Some services offer a “service” for cleaning candles using a sandblasting machine or ultrasound. On Nissan Note this is useless: Even if the spark plugs look like new, their service life has already been exhausted, and cleaning can damage the insulator. Better buy a new set.

Frequently asked questions about replacing spark plugs on a Nissan Note

Can I use spark plugs from other Nissan models (such as Juke or Qashqai)?

Theoretically yes, if they match thread size, heat rating and clearance. For example, candles from Nissan Juke with engine HR16DE suitable for Note with the same motor. However, it is better to follow the manufacturer’s recommendations: in the manuals for Note spark plugs with optimized characteristics for its ignition system are indicated.

What happens if you don’t change spark plugs for more than 100,000 km?

On engines Nissan Note with mileage over 100,000 km on worn spark plugs they begin irreversible processes:

• Electrode erosion leads to misfires and increased load on the catalyst (it may melt).
• Increases fuel consumption by 10–15% due to inefficient combustion.
• Carbon deposits on the spark plug insulator can cause glow ignition (uncontrolled ignition of the mixture from hot particles), which leads to detonation and damage to the pistons.

On turbocharged HR12DDR the consequences are even more serious: a bad spark leads to turbine overheating and reducing its resource.

Do I need to adjust the gap on new spark plugs?

Gap on original Nissan spark plugs and high-quality analogues (NGK, Denso) are already adjusted at the factory and do not need to be checked. However, if you buy candles unknown manufacturer or they were stored in unsealed packaging, the gap may “go away”. Check it out flat probe (not round!), since the electrodes often have uneven wear.

Is it possible to replace only one spark plug if the others are in good condition?

Technically yes, but highly not recommended. Plugs wear out evenly, and if one fails, the others will soon follow. In addition, different gap or condition of the electrodes will lead to uneven operation of the cylinders, which is fraught with vibrations and increased engine wear. An exception is if the spark plug is mechanically damaged (for example, a cracked insulator).

How often do you need to check the condition of the spark plugs if the car is used little (up to 10,000 km per year)?

Even with low mileage, spark plugs age due to oxidation of electrodes and loss of insulator tightness. It is recommended to check their condition every 2 years, regardless of mileage. This is especially true for cars that are often parked with the engine not running in a humid climate - condensation accelerates corrosion.
