Replacing spark plugs on a Nissan Qashqai: step-by-step guide with photos and videos

Replacing spark plugs with Nissan Qashqai is one of the key maintenance procedures that directly affects engine stability, fuel consumption and acceleration dynamics. Many owners Kashkaev (especially models J10 (2006–2013) and J11 (2013–2021)) postpone this operation until the last minute, until the engine begins to “triple”, jerk or consume oil. Meanwhile, timely replacement of spark plugs allows you to avoid costly repairs of ignition coils, catalyst or even cylinder block.

In this article we will look at step by step instructions for replacing spark plugs Qashqai with gasoline engines HR16DE (1.6 l), MR20DE (2.0 l) and M9R (2.0 diesel, where the glow plugs are changed according to a different pattern). You will also find out what Nissan recommends spark plugshow often to change them, and what hidden nuances can turn a simple procedure into a nightmare for a beginner. If you have never held a spark plug wrench in your hands, don’t worry: with the right approach, replacement will take no more than an hour.

When to change spark plugs on a Nissan Qashqai: regulations and signs of wear

Official regulations Nissan requires replacement of spark plugs every 30,000 km for ordinary nickel spark plugs and 90,000–100,000 km for iridium or platinum. However, these figures are relevant for ideal conditions: high-quality fuel, a calm driving style and no overheating. In reality, candles are on Qashqai often fail earlier:

• 🔥 Engine tripping - the most obvious symptom. The engine “tweaks” at idle or during acceleration, vibrations are released into the cabin.
• ⚡ Misfires (errors P0300–P0304). Lights up on the dashboard Check Engine.
• 🛢️ Increased fuel consumption — worn-out spark plugs lead to incomplete combustion of the mixture, which “eats” 10–15% of gasoline.
• 🚗 Bad start — the engine takes a long time to “catch up”, especially in cold weather or after short trips.

On Qashqai J11 with motor MR20DE (2.0 l) candles often “die” by 50–60 thousand km due to design features: high temperature in the combustion chamber and tendency to carbon deposits. Owners HR16DE (1.6 l) encounter problems less often, but there are pitfalls here too - for example, sticking of candles due to thread corrosion (relevant for regions with salty roads).

⚠️ Attention: If detected on candles red plaque (evidence of ferrocene additives in gasoline) or oil soot — the problem is not in the spark plugs, but in the fuel or the condition of the CPG (cylinder-piston group). Replacing spark plugs is only a temporary solution.

Which spark plugs are suitable for Nissan Qashqai: original vs analogues

Nissan recommends installing original candles with articles:

• 22401-JM00A - for HR16DE (1.6 l, J10/J11);
• 22401-4M015 - for MR20DE (2.0 l, J11).

However, their price (from 800–1,200 rub. per piece) often forces owners to look for analogues. Among the tested options:

Manufacturer	Article	Type	Compatibility	Price per piece, rub.
NGK	IFR6T11	Iridium	HR16DE, MR20DE	600–800
Denso	IK20TT	Iridium	MR20DE	700–900
Bosch	FR7DPX	Platinum	HR16DE	500–700
Beru	Z323	Nickel	Budget option	200–300

For Qashqai J11 with motor MR20DE better to choose iridium spark plugs - they last longer and cope better with high temperatures. On HR16DE You can also install platinum ones, but only if you do not plan to drive on gas (iridium is more resistant to propane-butane).

⚠️ Attention: Candles NGK IFR6T11 And Denso IK20TT Look similar, but have a different gap! For MR20DE there should be a gap 1.0–1.1 mm, and for HR16DE — 0.8–0.9 mm. Check before installation!

Tools for replacing spark plugs on a Nissan Qashqai: what you need

To replace spark plugs yourself Qashqai you will need a minimum set of tools:

• 🔧 Candle key with a rubber seal (for example, 16 mm for HR16DE or 14 mm for MR20DE).
• 🔩 Extension cord And ratchet (at least 20 cm long for access to the rear spark plugs).
• 🔧 10 mm head - for removing ignition coils.
• 🧲 Magnetic gripper or tweezers - so as not to drop the candle into the well.
• 🧴 Dielectric grease (For example, Liqui Moly) - for processing coil tips.
• 🧹 Compressor or can of compressed air - for cleaning wells from dust.

If the candles got stuck (relevant for cars older than 5 years), additionally prepare:

• 🔥 WD-40 or decarbonizer (For example, LAVR ML202).
• 🔧 Torque wrench (so as not to break the thread when tightening).

On Qashqai J11 Access to the spark plugs is difficult due to the tight layout of the engine compartment. To get to the rear spark plugs (interior side), you may need to remove intake manifold or throttle assembly. If you have little experience, it’s better not to take risks and contact the service.

Step-by-step instructions: how to change spark plugs on a Nissan Qashqai

The process of replacing spark plugs Qashqai differs depending on the engine model. Below are universal instructions taking into account the nuances for HR16DE And MR20DE.

Step 1: Prepare and provide access

1. Disable negative battery terminal (this will prevent a short circuit when removing the coils).

2. Remove decorative engine cover (on J11 it is secured with 4 latches).

3. Clean the space around the spark plug wells from dust and dirt (you can use vacuum cleaner or brush). Debris getting into the cylinders is the main reason for repairs after a “makeshift” replacement of spark plugs!

Step 2: Removing the Ignition Coils

On Qashqai are used custom coils for each cylinder. To remove them:

1. Disconnect power connector from the reel (press the lock and pull up).
2. Unscrew fastening bolt coils (head on 10 mm).
3. Carefully remove the spool by rocking it from side to side. If it “sticks”, do not pull with force - spray WD-40 and wait 5-10 minutes.

Step 3: Removing Old Spark Plugs

1. Paste spark plug wrench into the well and carefully screw it onto the candle.

2. Pull the key up - if the spark plug does not budge, do not apply excessive force! Return the key to its original position and try again after processing WD-40.

3. Inspect the removed spark plug:

• 🔥 Normal Wear — light brown soot, electrodes are intact.
• ⚠️ Oil soot - black deposits, a sign of problems with the valve stem seals.
• ❌ Destroyed electrode - The ignition coil needs to be checked.

Step 4: Installing New Spark Plugs

1. Check gap on new spark plugs (must meet the recommendations for your engine).

2. Gently screw in the spark plug by hand all the way, then tighten torque wrench with force:

• HR16DE — 20–25 Nm;
• MR20DE — 18–22 Nm.

3. Reinstall the coils, connect the connectors and tighten the bolts.

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

If the spark plug electrode remains inside, do not try to remove it yourself! Use a special extractor for broken spark plugs (sold in car dealerships) or contact service. Attempts to unscrew the piece with pliers almost always end in damage to the threads in the cylinder head.

Step 5: Check operation

After replacement:

1. Connect battery terminal.
2. Start the engine and check no misfires (the motor should run smoothly, without vibration).
3. If it catches fire Check Engine — reset the error using a scanner or by disconnecting the battery for 10 minutes.

Common mistakes when replacing spark plugs on a Qashqai and how to avoid them

Even experienced car owners sometimes make mistakes that lead to serious damage. Here are the most common of them:

• 🔧 Re-upholstery of candles - leads to damage to the threads in the cylinder head (cylinder head). Correcting only by replacing the cylinder head or cutting a new thread.
• 🧹 Debris getting into the cylinders - even a small grain of sand can scratch the cylinder mirror and lead to oil glutton.
• ⚡ Heat number mismatch - “cold” spark plugs (with a large number) provoke carbon deposits, “hot” spark plugs – detonation.
• 🔌 Confusion with high voltage wires - on Qashqai J10 this leads to misfires and mistakes P030X.

Another typical problem is broken candle when unscrewing. This happens due to:

• Thread sticking (especially on machines older than 5 years).
• Using a low-quality wrench (for example, with a “broken” hexagon).
• Applying force at an angle (the spark plug wrench must go strictly along the axis of the spark plug!).

⚠️ Attention: If after replacing the spark plugs the engine begins to run worse (popping noises, loss of power), check coil connection sequence. On Qashqai The cylinders are numbered on the timing side: cylinder 1 is closest to the belt.

How much does it cost to replace spark plugs on a Nissan Qashqai at a service center?

The cost of replacing spark plugs in a car service depends on the region, type of spark plugs and difficulty of access. Average prices in Russia (for 2026):

Type of work	Price, rub.	Notes
Replacing spark plugs (4 pcs.)	1 500–3 000	Without the cost of candles, for HR16DE/MR20DE
Replacement + error diagnosis	2 500–4 000	Includes reset Check Engine
Removing a broken spark plug	3 000–6 000	Depending on complexity
Complex replacement (plugs + coils)	8 000–12 000	Relevant for misfires

At official dealerships Nissan the price is 30–50% higher, but they guarantee original spare parts and high-quality work. Unofficial services often skimp on tools (for example, they use universal wrenches instead of specialized ones), which increases the risk of thread damage.

If you decide to change the spark plugs yourself, save 1,500–3,000 rubles., but be prepared for possible difficulties:

• 🔧 On Qashqai J11 Access to the rear spark plugs is difficult - removal of the intake manifold may be necessary.
• 🔥 Sticky candles sometimes have to be “soaked” for several hours.
• ⚡ It’s not always possible to clear errors without a scanner Check Engine after replacement.

Frequently asked questions about replacing spark plugs on Nissan Qashqai

Is it possible to drive with faulty spark plugs?

Technically yes, but this leads to:

• Increased fuel consumption (up to 20%).
• Catalyst overload (may melt).
• Detonation, which destroys pistons and rings.

If the spark plug is completely out of order (for example, the electrode has broken off), you cannot drive - this is fraught with breakdown of the ignition coil.

Do I need to change the ignition coils along with the spark plugs?

Not required, but recommended to check their status:

• 🔍 Inspect the coils for cracks or reflow.
• 📊 Check the resistance of the primary/secondary winding with a multimeter (normal: 0.5–2.0 Ohm And 6–15 kOhm respectively).

If there was heavy carbon deposits or oil deposits on the spark plugs, the coils could be damaged - replacing them would cost 2,000–3,500 rub. per piece.

Which spark plugs are best for Qashqai on gas?

Optimal for cars with HBO iridium spark plugs with less clearance:

• NGK IFR6T11 (gap 0.7 mm).
• Denso IW20TT (gap 0.8 mm).

Gas burns slower than gasoline, so regular spark plugs may not provide consistent ignition.

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

Causes and solutions:

• 🔌 Incorrect coil connection — check the order (cylinders 1–4 from the timing side).
• 🔧 Poor contact — clean the coil connectors.
• ⚡ Marriage candles — swap the spark plugs from the “triple” cylinder with a known good one. If the problem has moved, the spark plug is defective.

Can old candles be cleaned and reused?

Technically yes, but this temporary solution. Candles can be:

• 🧹 Clear sandblasting or a wire brush.
• 🔥 Heat on a gas burner (removes soot).

However, even after cleaning electrode gap increases, and thermal performance deteriorates. The maximum resource of “restored” candles is 5–10 thousand km.
