Auto parts spark plug parts

The Spark Plug is a threaded electrode which screws into a combustion chamber whose job it is to provide a spark at the appropriate time in order to create a controlled explosion in the chamber, therefore delivering horsepower to a vehicle.It features a copper core with a platinum tip, designed to reduce the required firing voltage, help slow erosion and offer extra protection against fouling.

Why is quality so important for spark plugs?

If your owner’s manual calls for double platinum spark plugs, then those are the best ones you can use.  Never downgrade to single platinum spark plugs, they aren’t able to handle the waste spark in that particular DIS.   You can, however, upgrade to an iridium/platinum combo (an iridium electrode with a platinum-tipped side electrode). 

When getting or performing a tune-up on your car, or if you just want to improve your car’s performance, make sure you use high quality spark plugs. Poor or worn out spark plugs will misfire, cause your car to lose fuel efficiency, create exhaust issues, and cause your car to lose power or run poorly.  Continued misfire in your car’s engine will lead to an whole line of issues, so make sure you choose the best set that fits your needs.

* Strict quality control.

* Technical support After-sales service.


FAQ:

Q: WHAT IS A FOULED SPARK PLUG?

A: A spark plug is considered fouled when the insulator nose at the firing tip becomes coated with a foreign substance such as fuel, oil or carbon. This coating makes it easier for the voltage to follow along the insulator nose, leach back down into the metal shell and ground out rather than bridging the gap and firing normally.
Many factors can contribute to spark plug fouling. The air-fuel ratio may be too rich as a result of incorrect carburetor adjustment or a poorly performing fuel injection system. Worn piston rings or valve seals may allow too much oil to leak into the combustion chamber, leading to oil fouling. The ignition system may not be performing properly. Prolonged idling or continuous low-speed driving may keep the spark plug from reaching its optimum operating temperature. Using too cold a spark plug can lead to the same problem. Finally, a dirty air cleaner can create a too-rich condition which can lead to fouling.
Fuel, oil and carbon fouling can all be the result of different causes but, once a spark plug is fouled, it will not provide adequate voltage to the firing tip and that cylinder will not fire properly. Therefore, it is recommended that a plug be replaced once it is fouled.

Q: WHEN SHOULD I USE A RESISTOR SPARK PLUG?

A: Vosirui "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.
Vosirui strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics.
They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.
In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion.

Q: WHY ARE THERE DIFFERENT HEAT RANGES?

A: It is a common misconception that spark plugs create heat. They don't. A heat range refers to how much heat a spark plug is capable of removing from the combustion chamber.
Selecting a spark plug with the proper heat range will ensure that the tip will maintain a temperature high enough to prevent fouling yet be cool enough to prevent pre-ignition. While there are many things that can cause pre-ignition, selecting a spark plug in the proper heat range will ensure that the spark plug itself is not a hot spot source.

Q: UNDERSTANDING HEAT RANGE?

A: One of the most misunderstood aspects of spark plugs is its heat range. It is believed by many that the heat range measures spark temperature or intensity. This is incorrect as the heat range is actually a measurement of the plug’s ability to transfer heat away from the tip of the spark plug. One cannot change the temperature of how hot a fuel burns.

A hot spark plug has an insulator design that will be slower to draw heat away from the plug tip (thinner insulator mass), whereas a cold plug has an insulator design that will be faster to draw heat away from the plug tip (thicker insulator mass). For a spark plug to function properly it must have a tip temperature hot enough to invoke self-cleaning, while remaining cool enough to avoid pre-ignition.

For most vehicles, the factory recommended heat range is sufficient; however, on some modified or special-use engines, alternative heat ranges may be necessary. Often hotter heat ranges have been used to attempt to correct an underlying fuel or oil consumption problem; this is merely a cover-up fix and the underlying issues will ultimately have to be addressed.

The image below is a representation of the difference between a hot and cold heat range. Vosirui spark plugs’ heat range goes from 2 (hottest) to 11 (coldest).

Q: HEAT RANGE SELECTION?

A: Let's make this really simple: when you need your engine to run a little cooler, run a colder plug. When you need your engine to run a little hotter, run a hotter spark plug. However, Vosirui Spark Plugs strongly cautions people that going to a hotter spark plug can sometimes mask a serious symptom of another problem that can lead to engine damage. Be very careful with heat ranges. If you are changing heat ranges, contact Vosirui Spark Plugs tech support for professional guidance, +86 18319079303.
With modified engines (those engines that have increased their compression,) more heat is a by-product of the added power that normally comes with increased compression. In short, select one heat range colder for every 75-100 hp you add, or when you significantly raise compression. Also remember to retard the timing a little and to increase fuel enrichment and octane. These tips are critical when adding forced induction (turbos, superchargers or nitrous kits), and failure to address ALL of these areas will virtually guarantee engine damage.
An engine that has poor oil control can sometimes mask the symptom temporarily by running a slightly hotter spark plug. While this is a band-aid approach, it is one of the only examples of when and why one would select a hotter spark plug.

A: It is essential to tighten a spark plug to the specified turning angle or torque setting. First, screw in the plug finger tight until the gasket meets the cylinder head. Then seat the plug/gasket with a torque or turning angle wrench as specified in the chart below. 

This is very important, as excessive tightening of a spark plug can cause breakage of the metal shell and damage to the interior seals. At the same time, insufficient tightening can lead to overheating of the spark plug and potential detonation.
