Many owners are faced with the problem of choice, since the auto parts market is oversaturated with offers of varying quality. Incorrect selection or use of non-original parts can lead to increased fuel consumption, loss of power and even failure of the ignition coils. In this article we will look at which candles are suitable for your Nissan Note, how to replace them correctly and what signs of malfunction you should pay attention to first.
1.6 liter engine installed on Nissan Note (model series E11 and E12), belongs to the HR16DE series. This is a modern power unit with phase shifters, which requires high precision sparking. Standard clearances and thermal characteristics must strictly comply with the manufacturer's specifications. Any deviations in the operation of the ignition system will immediately affect the environmental friendliness of the exhaust and the dynamic characteristics of the car.
Particular attention should be paid to the type of electrodes. Depending on your mileage and operating conditions, you may find it necessary to replace conventional nickel spark plugs with more durable iridium or platinum counterparts. Choosing the right type affects not only service intervals, but also the stability of the engine in the cold season.
Original articles and specifications
When searching for spare parts for Nissan Note 1.6, first of all you need to focus on the original catalog numbers. The manufacturer installs candles produced by the company NGK, which are perfectly balanced for the operation of this motor. The main item that can be found in specialized stores is 22401-ED00A or its analogues from the series 22401-ED01A.
In addition to the original packaging with the Nissan logo, candle manufacturers offer direct analogues, which are often cheaper and have identical technical parameters. For the HR16DE engine, the most suitable models are those marked ILKAR6C11 from NGK or PZFR5R-11 from Denso. These products have an iridium center electrode, which ensures long service life and a stable spark even under high loads.
- 🔧 NGK ILKAR6C11 - iridium spark plug with a gap of 1.1 mm, recommended by the manufacturer.
- ⚡ Denso PZFR5R-11 is a similar iridium model with a double grounding electrode.
- 🏭 OEM Nissan 22401-ED00A is an original part, often packaged in a branded box.
- 🛠️ NGK LKAR6AI-8622 - option with double electrodes, suitable for replacement if there are no iridium electrodes.
It is important to understand that the technical characteristics of spark plugs are not universal for all 1.6 liter engines. An error in the choice of thread, heat rating or gap can lead to the fact that the spark plug simply does not fit in size or will not work correctly, causing detonation.
⚠️ Attention! Don't try to save money by installing spark plugs from other Nissan models with a similar engine size. Even a slight difference in thread length can cause the piston to strike the electrode or damage the threads in the cylinder head.
When purchasing, always check the labeling on the packaging and the candle itself. Counterfeits often have uneven threads, poor insulation and incorrect clearance, which cannot be determined without special equipment. Trust only trusted suppliers and large retail chains.

Symptoms of wear and signs of malfunction
Engine Nissan Note reacts quite sensitively to problems with the ignition system. If you notice that the car has started to work unstably, the first thing you should do is check the condition of the spark plugs. One of the most obvious signs is idle melting, when engine speed begins to “jump” without driver intervention.
Another warning sign is difficulty starting the engine, especially in cold weather. Old or dirty spark plugs cannot provide enough energy to ignite the air/fuel mixture, causing the starter to crank for long periods of time. In some cases, the engine may not start at all if there is no spark in one or more cylinders.
- 🚗 Increased fuel consumption - inefficient combustion of the mixture requires more gasoline to maintain power.
- 📉 Loss of acceleration dynamics - the engine “does not pull”, especially when overtaking or going uphill.
- ⚙️ Dips when accelerating - the engine jerks or stalls when you press the gas pedal sharply.
- 💡 Check Engine light comes on - the on-board computer detects misfires and displays error P0300 or P0301-P0304.
Sometimes the problem may not be in the spark plug itself, but in the contamination of its electrodes with soot or oil. This occurs due to wear of the oil seals or piston rings, but is often a consequence of using low-quality fuel. A visual inspection allows you to quickly assess the condition of the elements and make a decision on replacement.
⚠️ Attention! If the Check Engine light comes on and the engine is running rough, do not ignore the problem. Prolonged operation with misfires can lead to overheating and destruction of the catalytic converter, the replacement of which is very expensive.
Some owners mistakenly believe that if the car starts, then the spark plugs are working. However, even with a spark, if it is weak or unstable, combustion efficiency will decrease. This leads to the accumulation of carbon deposits and a gradual loss of engine life.
Instructions for self-replacement
Replacing spark plugs on an HR16DE engine is not a difficult task and can be done in a regular garage. You will need a socket set, wrenches, extensions and a torque wrench for precise tightening. The process requires care, since access to the spark plugs may be limited due to the close proximity of the ignition coils and other components.
The first step is to turn off the power to the car by disconnecting the negative terminal of the battery. Next, remove the decorative plastic engine cover, if equipped, to gain access to the ignition coils. Each coil is secured with one bolt and has an electrical connector that must be carefully disconnected.
☑️ Preparation for replacement
After removing the coils, use a spark plug wrench with an extension to unscrew the old elements. Be extremely careful not to drop foreign objects inside the candle well. If the spark plug is stuck, do not use excessive force right away; it is better to pre-treat the joint with penetrating lubricant.
- 🧹 Blow compressed air into the recesses under the spark plugs before unscrewing them to prevent dirt from getting into the cylinders.
- 🔩 Check the condition of the rubber seals on the reels - they must be intact and elastic.
- 📏 Use a torque wrench to tighten new spark plugs according to the torque specified in the instructions.
- ⚙️ Apply a thin layer of copper grease to the threads of the new spark plug to prevent future sticking.
Installing new spark plugs is done in the reverse order. It is important not to overtighten them, as this can lead to destruction of the ceramic or damage to the threads in the cylinder head. Typically, the tightening torque for spark plugs with a rubber seal is about 13 Nm, but it is better to check this value in the technical documentation.
What to do if the spark plug is stuck?|If the spark plug does not unscrew, do not try to rip it out of place with a sharp jerk. Try swinging the key slightly in both directions, using a little force. You can also warm up the block head carefully with a hair dryer, but not with a gas burner, so as not to damage the sensors. If all else fails, it is better to contact a service that uses special extractors.-->
⚠️ Attention! Never use a regular spark plug wrench without a magnetic holder or locking extension. You could lose a spark plug inside the engine and have to remove the cylinder head to remove it, turning a simple replacement into a major overhaul.
After installing all the elements and connecting the coils, be sure to check the operation of the engine. It should work smoothly, without vibrations or extraneous noise. If the Check Engine Light does not go off immediately, you may need to clear the fault using the scan tool.
