High-Performance Iridium Spark Plug
HiVehicle iridium spark plug uses the precious metal-iridium with high temperature resistance, ablation resistance and excellent oxidation resistance. The diameter of the ignition end of the center electrode is close to 0.6MM, the ignition is stronger, the combustion is cleaner, the fuel saving is obvious, and it has a strong anti-interference effect, and the service life is 3-5 times that of a general spark plug.
Feature
Iridium Tip-Better than OE
360° continuous laser welded center electrode create reliable resistance to thermal shock occurred in new generation engines.
0.6mm Ultra fine wire iridium center electrode provide better ignitability
Embedded Copper Core
Copper cored center electrode has better heat dissipation, dissipate a lot of heat as quickly as possible to prevent overheating of spark plug firing end and engine damage.
Resistance powder
Glass sealant with resistors ensure conductivity and sealing property,provide protection from radio interference too.
Ceramic Insulator
Newly developed high performance ceramic T95 with excellent insulation, heat resistance and thermal conductivity required by spark plugs.It ensures outstanding dielectric mechanical strength of insulator.
Analysis of the Cause for Abmormal Combustion
The proper servcing of spark plugs can help make the differnce in good engine performance and fuel economy.
An engine with adequate compression and proper fuel/air mixture may fail to properly ignite the fuel charge in one or more serveral ways,depending on the condiction of the spark plugs.
Misfire could be caused by improper fuel/air mixture in the cylinder.
However,the problem is more comonly caused by faulty ignition.

Spark Plug TIP Diagnosis
Normal
The nose of insulator appears yellow-brown,brown or lightish gray,electrode erosion is light.It shows the spark plug is suitable for engine.
Electrode Melted
The end of center electrode and ground electrode appear melted.
Cause:Overheating
Action:Regarding to type of spark plug,change to install a colder type of spark plug or higher heat range of spark plug.
Overheated
The insulator nose appears bleached white electrode melted
Cause:Pre-ignition,insufficient cooling,low octane gasoline and thin fuel mixture are used.Spark plug extended into the combustion chamber is too long or a too hot spark plug be used.
Action:Install a new colder type of spark plug
Lead Pollution
The color of the insulator appears powder white,yellow,yellowish,brown,green and black
Cause:When an engine operate in low load speed,the 4 ethyl lead in gasoine deposit on the nose of insulator.While the engine accelerates,it operates in a high speed,heavy load condition,the temperature of spark plug increase further,then conductivity of the lead compound formed on the insulator surface increases,therefore causing the misfiring of spark plug.
Action:Avoid using lead gasoline,or change touse a hotter type of spark plug

The picture accurately describes the product.These spark plugs did the job. One of the car apps stated these would not fit my car; however, my mechanic said they fit perfectly. Additionally, he said the price is right especially compared to other companies.It has only been a little more than a month so I am unable to comment about durability. I will update if I have concerns in the future.I recommend this product.

These spark plugs are solid performers and do a good job. They were easy to install in my car and the installation process was quick and easy. These spark plugs fit my car and perform well. These sparkplugs appear to be put together well and feel like they are quite durable. These sparkplugs have been in my car for a little while now and I have not had any issues or trouble, which I am happy about. A good spark plug that performs well and is easy to work with.
