The center and ground electrodes of double iridium spark plugs are laser fused using iridium. This makes them more resistant to higher temperature conditions, and it's used in industrial combustion engines. Double iridium spark plugs outperform other types of spark plugs such as copper spark plugs in terms of overall performance, longevity, durability, and voltage. Double-iridium spark plugs have two rare-metal discs that boost durability and performance, similar to double-platinum spark plugs. This improved durability makes them four times stronger than copper alternatives, allowing your car to run at higher speeds for longer periods.
Benefits of Spark Plug Double Iridium
Better overall performance
The precision engineering and laser-welded surfaces that make up the iridium spark plug allow for a more responsive and more efficient spark plug. The iridium electrodes provide the spark plug with greater heat and corrosion resistance as well as improving charge retention.
Long lifespan
Double iridium spark plugs withstand higher temperatures and pressures during the combustion process, increasing lifespan. Double iridium spark plugs have a lifespan estimated to be up to four times that of traditional, non-precious metal plugs, and 125% that of similar platinum-based devices.
Durability
Iridium is an extremely tough, resistant metal with a high melting point, which strengthens the overall build quality of anything it's used in. It's an excellent choice for high-pressure, high-temperature environments, such as the inside of a gas-fuelled combustion engine.
Limited visible deterioration
One problem with all commercially available spark plugs is that they tend to break apart and carbonise with age and repeated use. Iridium's strength allows it to survive intact for much longer, maintaining a consistent electrode gap.
Lower voltage
Iridium's better conductivity means that a much lower voltage is sufficient to cause a spark when passed through the metal. This helps to extend the lifespan of each iridium spark plug, as the gradual damage caused by a heavy flow of electricity is reduced.
Components of Spark Plug Double Iridium
Terminal
The connection terminal is usually an SAE 'barrel' shaped connection, a 4 mm thread or a 'cup design'. The high tension ignition lead or a pencil coil is plugged onto the terminal. This connection allows the high voltage to be transferred to the firing end of the spark plug.
Ceramic insulator
Most spark plugs used today feature a single-ceramic insulator made from aluminium oxide, with other types of ceramic materials like porcelain used in the past. This provides many benefits, including thermal conductivity and superior insulation. Resistance to overheating, thermal and mechanical shock are other stand-out features. It also helps to prevent overheating and provides exceptional resistance against mechanical and thermal shock.
Resistor
In order to ensure electromagnetic compatibility (EMC) and thus the fault-free operation of the onboard electronics, a ceramic resistor is used inside the spark plug as an interference suppression device. It is constructed by a fusion of carbon and glass compounds which form a solid component within the spark plug. It also prevents interference with electronic components that are not located on the vehicle e.g. domestic TV and radios.
In most vehicles, a resistor spark plug is required for optimum operation because radio frequency interference (RFI) can cause the other electrical components in the car to break down prematurely.
Centre electrode
The centre electrode can be made from nickel, copper, chromium and precious metals such as iridium and platinum.
It is connected to the terminal by an internal copper wire, which carries high electrical voltage through the spark plug to the tip of the centre electrode, where it then jumps the small gap to the ground (side) electrode, creating a spark.
Ground (Side) electrode
Once the spark jumps the gap from the centre electrode to the ground electrode, a spark is created which ignites the fuel in the combustion chamber.
The ground electrode can come in a variety of shapes and sizes. Some (multi-ground spark plugs) can even feature two, three and four ground electrodes. These, however, do not create more sparks than a spark plug with one ground electrode.
For both single and multi-ground electrode spark plugs, only one spark is created at a time. Standard spark plugs generally feature a ground electrode made of nickel, while premium plugs feature precious metals such as iridium and platinum which, due to their hardness, are much more durable than standard metal plugs.
Gasket
The gasket ring prevents any possibility of combustion gas leaking past the spark plug due to the extremely high combustion pressures. In doing this, it prevents any cylinder pressure losses.
Another important function is that it provides good conduction of head to the cylinder head and evens out the different expansion properties of the cylinder head and spark plug housing.
Metal shell
This is the steel shell which a socket wrench fits around in order to loosen and tighten a spark plug. A plug's hex head can come in a variety of sizes, which include 13mm, 14mm, 16mm, 18mm, 19mm, 21mm, 22mm, 24mm, 25mm and Bi-Hex 14.0mm.
Ribs or corrugation or leakage barriers
Located above the terminal, the ribs help to protect against spark flashover.
Process of Spark Plug Double Iridium
Gather all necessary tools and materials: Before starting the installation process, ensure that you have all the required tools and new iridium spark plugs ready.
Cool down your engine: Make sure your engine is cool before working on it to avoid burns or other injuries. Wait for the engine to chill off completely before continuing with the installation.
Determine proper gap size: If specified by your vehicle's manufacturer, use a spark plug gap gauge to check and adjust each new iridium spark plug according to their recommendations. You can find this information in your owner's manual or online resources like NGK's website.
Remove old spark plugs one at a time: To prevent confusion when reinstalling the spark plug wire, remove and replace each spark plug one at a time. Use your ratchet wrench with the appropriate socket to carefully loosen and remove the old spark plug.
Inspect the removed spark plugs: Check for any signs of damage or wear on the old plugs. This can help you diagnose potential engine issues that may need further attention.
Clean the spark plug hole: Before installing new iridium spark plugs, use a clean cloth or rag to wipe away any debris from around the hole where it will be inserted.
Install new iridium spark plugs: Gently insert each new iridium spark plug into its respective hole by hand until snug. Then, using your torque wrench (if available), tighten them according to the manufacturer's specifications found in your owner's manual. If not using a torque wrench, make sure they are tightened securely but avoid over-tightening as this could cause damage to the spark plug threads in the cylinder head. Reinstall the spark plug wire before moving to the next cylinder.
Torque specification
Tighten spark plugs to the manufacturer's specified torque using a torque wrench to prevent over-tightening or under-tightening, which can cause damage to the threads or cylinder head.
Regular inspection
Periodically inspect spark plugs for signs of wear, fouling, or carbon deposits. Replace spark plugs at the recommended intervals to maintain optimal engine performance.
Carbon fouling
If spark plugs become fouled with carbon deposits, remove and clean them using a wire brush and solvent. Be careful not to damage the electrodes during cleaning.
Electrode wear
Monitor electrode wear over time and replace spark plugs if the electrodes are worn down or damaged. Worn spark plugs can cause misfires, engine hesitation, and reduced fuel efficiency.
How to Maintain Spark Plug Double Iridium
Gap adjustment: Ensure the spark plug gaps are correctly set according to the vehicle manufacturer's specifications. Improper gap settings can lead to misfires, rough idling, and poor fuel economy.
Thread lubrication: Apply a small amount of anti-seize compound to the spark plug threads before installation to prevent seizing and help future removal.
Some Factors to Consider in Selecting the Proper Heat Range Spark Plug
Engine speed and load
A: If the engine is to be operated at high RPM, under a heavy load, or at high temperatures for long periods a colder heat range may be needed.
B: Conversely, if the engine is to be operated at low speeds or at low temperatures for long periods, a hotter heat range might be needed to prevent fouling.
Air-fuel mixture
A: Excessively rich air-fuel mixtures can cause the plug tip temperatures to decrease and carbon deposits to accumulate, possibly causing fouling and misfires.
B: Excessively lean air-fuel mixtures can cause the cylinder and plug temperatures to increase, possibly resulting in knock and/or pre-ignition. This may cause damage to the spark plug and/or seriously damage the engine.
C: If an air-fuel ratio meter or gas analyzer is not available, it will be necessary to visually inspect the spark plugs frequently during the tuning process to determine the proper air-fuel mixture.
Fuel type / quality
A: Low quality and/or low octane fuel can cause knock which will elevate cylinder temperatures. The increased cylinder temperature will cause the temperature of the combustion chamber components (spark plug, valves, piston, etc.) to rise, and will lead to pre-ignition if the knock is uncontrolled.
B: When using an ethanol blend fuel with high ethanol content in high performance applications, a colder heat range may be necessary. The spark timing can be advanced further because ethanol blend fuel has a higher resistance to knock (higher octane). Due to the decreased knock, there will be less audible "warning" from knock before the spark plug overheats and pre-ignites.
C: Some types of fuel additives in lower quality fuels can cause spark plug deposits that can lead to misfires, pre-ignition, etc.
Ignition timing
A: Advancing ignition timing by 10° will cause the spark plug tip temperature to increase by approximately 70° to 100°C.
B: A colder heat range spark plug may be necessary if the ignition timing has been advanced to near the knock level. Higher cylinder temperatures near the knock level will bring the spark plug firing end temperature closer to the pre-ignition range.
Compression ratio
Significantly increasing the static/dynamic compression ratio will increase cylinder pressures and the octane requirement of the engine. Knock may occur more easily. If the engine is operated near the knock level, a colder heat range spark plug may be necessary due to the resulting increased cylinder temperatures.
Forced induction (turbocharging, supercharging)
A colder heat range spark plug may be necessary due to the increased cylinder temperature as boost pressure (manifold pressure) and subsequent cylinder pressure and temperature increase.
Ambient air temperature / humidity
A: As the air temperature or humidity decreases, the air density increases, requiring a richer air-fuel mixture. If the air-fuel mixture is not properly richened, and the mixture is too lean, higher cylinder pressures / temperatures, knocking, and the subsequent increase in the spark plug tip temperatures can result.
B: As the air temperature or humidity increases, the air density decreases, requiring a leaner air-fuel mixture. If the air-fuel mixture is too rich, decreased performance and/or carbon fouling can result.
Barometric pressure / altitude
A: Air (atmospheric) pressure and cylinder pressure decrease as altitude increases. As a result, spark plug tip temperature will also decrease.
B: Fouling can occur more easily if the air-fuel mixture is not adjusted to compensate for the altitude. Higher altitude = less air = less fuel
Yes, Iridium spark plugs can help you get more power from your engine. Iridium spark plugs require less voltage to fire and have a longer coil dwell time. This leads to improved combustion, reduced emissions, enhanced fuel economy, and increased horsepower.
The spark plug evolved with the internal combustion engine, but the earliest demonstration of the use of an electric spark to ignite a fuel-air mixture was in 1777. In that year, Alessandro Volta loaded a toy pistol with a mixture of marsh gas and air, corked the muzzle, and ignited the charge with a spark from a Ley den jar.
In 1860, French engineer Jean Lenoir created what most closely resembles the spark plug of today. He combined an insulator, electrodes, and spark gap in a single unit. As part of his patent application for the internal combustion engine that year, he devoted one sentence to describing the spark plug. He refined this spark plug in 1885.
In the early 1900s, Robert and Frank Stranahan, brothers and partners in an automobile parts importing business, set out to produce a more efficient and durable spark plug. They added gaskets between the metal shell and porcelain insulator, made manufacturing easier, and reduced the possibility of gas leakage past the gaskets. In 1909, Robert Stranahan sold the plug to one automobile manufacturer and went into the spark plug manufacturing business, cornering the market at that time.
What Are the Signs That You Need New Spark Plugs?
Fortunately, plenty of signs tell us that there's a problem with our spark plugs. And chances are you've felt one or two of these signs before, whether you knew it was because of your spark plugs or not. Here are some common ways you'll know to get your spark plugs replaced:
1.Hard starting: If you have a hard time starting your engine, and it isn't an issue with your car battery, then chances are high that your spark plugs aren't able to create enough spark for a smooth engine start.
2.High fuel consumption: Worn-out spark plugs keep engines from working as efficiently as they should. Therefore, if you find that your fuel consumption is getting higher then it's time to take a look at your spark plugs.
3.Rough idling: As your vehicle idles, you might feel it hesitating, shaking, or vibrating. There might even be a rattling sound due to the force of the pistons and combustion not working correctly.
4.Slow acceleration: If your car is harder to accelerate, it can also be because the spark plugs are not sparking as they should.
