The letter “R” on a spark plug indicates that it is a resistor type spark plug. Resistor spark plugs are designed to suppress electrical interference that can be caused by other electrical components in the vehicle’s ignition system, such as the alternator and distributor.
They feature a ceramic-like material around the spark plug’s electrodes, which resists the electrical charge and reduces the voltage being sent up the plug wires to the spark plug. Resistor spark plugs are ideal for vehicles with many electrical accessories, such as GPS systems, sound systems, and aftermarket performance upgrades.
Resistor spark plugs also reduce radio frequency interference and engine knocking, which can damage other engine components over time.
What is the difference between NGK and NGK R spark plugs?
NGK is a brand name for spark plugs, and NGK R spark plugs specifically refer to the resistor spark plug range of NGK spark plugs. The prefix ‘R’ indicates that the spark plug contains an internal resistor which creates an electrical resistance that suppresses the amount of electrical interference that is produced.
The resistor technology in NGK R spark plugs filters out radio noise created when the vehicle is in operation, meaning you may experience fewer issues with your radio, car stereo, and other technological components in your vehicle.
Additionally, the resistor may reduce the likelihood of corrosive damage to spark plug wires and other vehicle components. NGK R spark plugs also come in a variety of designs to suit a range of engine types, while all types of spark plugs vary in their heat ranges and projected performance to suit specific engine applications.
Are NGK R spark plugs good?
Yes, NGK R spark plugs are very good. They are known in the automotive industry as being reliable, durable and dependable, capable of delivering a powerful spark and promoting a smooth running engine.
The NGK R spark plugs feature a copper core that allows for maximum heat transfer and superior spark, providing a strong and robust spark for improved combustion and engine performance, as well as improving fuel economy.
Additionally, NGK R spark plugs come with an anti-corrosion coating and a stainless steel shell for enhanced durability, making them ideal for high-performance applications. So, if you’re looking for dependable, reliable performance and a powerful spark, then NGK R spark plugs are the perfect choice.
What do NGK codes mean?
NGK codes are part of the industry standard system that identifies specifications for spark plug designs. These codes are used by automotive engineers, mechanics, and technicians to select parts for vehicle engines.
NGK stands for Nippon (Japan) Gyakusyoku (Technique or Method) Kogyo (Industry). The codes consist of four parts: the prefix (NGK, DENSO, AUTOLITE, BOSCH, CHAMPION, AC DELCO) that identifies the brand; the first digit of the code (prefix + 7 or 8) that denotes the thread size; the last 2 digits that identify the heat range; and the material ground electrode (Y = Yttrium, A = Platinum, R = Platinum Double, U = Nickel).
Heat range is the measure of a spark plug’s ability to remove heat from the combustion chamber. A lower number indicates a colder heat range (more heat removed), while a higher number indicates a hotter heat range (less heat removed).
Each manufacturer uses its own heat range numbering system, so an NGK 6 could be a very different temperature range than an AUTOLITE 6.
Which is better a resistor or non resistor spark plug?
The answer to which is better, a resistor or non-resistor spark plug, will depend on the type of vehicle you have. Generally, non-resistor spark plugs are better for older vehicles, because they have a higher performance and better combustion as compared to resistor spark plugs.
In newer vehicles, however, resistor spark plugs are preferred because they can eliminate any interference caused by electronic systems, such as car alarms and other aftermarket accessories. They also reduce the amount of voltage leakage, which can produce a smoother fuel economy.
Ultimately, the best choice for your vehicle will depend on the vehicle’s age and the type of spark plug the vehicle was designed for.
What happens if you use a hotter spark plug?
If you use a hotter spark plug, the spark within the combustion chamber of the engine will be stronger, causing the fuel and air mixture to ignite faster and more completely, resulting in increased performance and better fuel efficiency.
The increased strength of the spark can also increase power output, as it allows for more fuel to be burned in a shorter amount of time. However, it is important to note that using a hotter spark plug can also cause pre-ignition and detonation, which can damage the engine over time, so it is important to use only the recommended type of spark plug for your engine.
Additionally, if you are using the correct and recommended spark plug, it is also important to regularly replace it as eventually it will wear away and not give off an optimum spark anymore, which could lead to potential problems.
How do you read NGK part numbers?
NGK (NTK) spark plug part numbers indicate not only the type of spark plug but also its heat range and thread size.
A typical NGK part number looks like this: BKR6E-11.
The first two characters (BK in this case) represent the spark plug series, which includes a large variety of spark plugs for different automotive applications.
The third character (R) represents the plug type, either resistor or non-resistor plug. It is important to note that this will differ from other manufacturers as NGK has their own resistor codes.
The fourth character (6) indicates the heat range. It is important to select the appropriate heat range so that the spark plug can be properly thermally balanced.
The fifth and sixth characters (E-11) represent the thread size and reach of the spark plug. The thread size is measured in millimeters and the reach is measured in millimeters or inches.
Overall, these part numbers can be used to accurately identify the spark plug you need. Care should be taken to ensure that you get the right plug for your specific application.
What is the NGK equivalent of RC12YC?
The NGK spark plug equivalent to a RC12YC is an NGK BPR6ES or BPR6EIX. These plugs have the same reach and heat range as a RC12YC plug and can be used as a suitable replacement. The BPR6ES is a copper core spark plug, while the BPR6EIX is a platinum tipped spark plug.
Both of these plugs feature a projected tip design, providing superior flame control for enhanced performance and better ignitability.
Can I use a resistor spark plug?
Yes, you can use a resistor spark plug. A resistor spark plug is a spark plug that contains a small resistor in its body, just below the spark plug terminal. The resistor is intended to reduce the voltage sent through the spark plug, which reduces the electrical interference caused by the spark.
This can help minimize the potential for engine misfire. Additionally, the slower burn time of a resistor spark plug can reduce the engine’s tendency to detonate when running under load. It is important to note, however, that resistor spark plugs can also cause the ignition system to run hotter, which can reduce the life of the spark plug and the ignition system, so they must be used with caution.
Do resistor spark plugs make a difference?
Yes, resistor spark plugs can make a difference when it comes to performance and wear of the spark plugs. Resistor spark plugs have a resistor included in the ceramic body of the spark plug and typically have an avoid or resistive wire wound within the spark plug body.
This resistor can reduce the effects of interference on the car’s electronics, providing better performance and improved fuel consumption. Resistor spark plugs also have a longer life and provide consistent performance over time.
They also offer increased robustness, which helps improve their durability over conventional spark plugs. Ultimately, resistor spark plugs can make your engine run better, save money and potentially have a longer lifespan than conventional spark plugs.
Can a resistor drain a battery?
The answer is yes, a resistor can drain a battery. This occurs when a resistor is connected directly in series with a battery. In this case, the battery will supply current to power the resistor. The resistor uses this current to convert it into heat, drawing energy from the battery.
This will reduce the energy stored in the battery and, once used up, the battery will no longer be able to provide energy to the circuit. Therefore, over time, the resistor will drain the battery of its energy.
What happens if resistor is too low?
If a resistor is too low, then it will not be able to regulate the current properly, causing the current to become too high. This can cause overheating of the resistor and other components in the circuit.
It can even cause damage in the circuit or destruction of the resistor, leading to expensive repairs. Additionally, too low of a resistor will reduce voltage in the circuit, not allowing other components to perform correctly.
It is important to select a resistor with the correct resistance level in order to ensure the components and circuit are able to work properly.
How do you know when a resistor is bad?
The main way to know if a resistor is bad is by testing it. You can do this with an ohmmeter, which measures the resistance in a circuit. If the reading on the ohmmeter is not what it should be for the given resistor, then the resistor is most likely bad.
Other indications of a bad resistor are if the resistor is charred, discolored, missing, or bloated. In some cases, you may also be able to tell if a resistor is bad by visual inspection.
What are 3 purposes of a resistor?
1. Resistor’s are commonly used to regulate current in a circuit by providing a specific amount of resistance. This resistance is measured in Ohms and varies depending on the type of resistor being used.
By adjusting this resistance, current flow through the circuit can be reduced or increased, allowing a designer to customize the amount of current the circuit is able to provide.
2. Resistor’s can also be used to create voltage division in a circuit. Voltage division occurs when an equal voltage is distributed among the components in a circuit. By using a resistor to create a voltage division, designers can create specific steady voltage outputs for data transmission or other applications.
3. Resistor’s are also commonly used as a circuit protection device. In the event of an over current or short circuit, resistor’s can be used to limit the amount of current passing through the circuit, thus protecting the components of the circuit from damage due to excess current.
Which type of spark plug is for?
Spark plugs are designed to deliver electric current from the ignition system to the combustion chamber in order to initiate the fuel/air mixture that powers the engine. The type of spark plug you need is determined by the type of engine you want to use in your vehicle.
For example, cars with carbureted engines need a larger gap spark plug than those on fuel injected engines, because the spark needs to cover a longer distance for it to ignite the fuel. Additionally, gas engines typically require a hotter spark compared to diesel engines.
The type of spark plug that is right for your engine can also change depending on other factors, such as the type of fuel you are using, the altitude you are operating in, or the type of ignition system your engine uses.
Choosing the right spark plug can help to maximize the performance of your engine, so it is important to select the right one for the intended application.
