Re: What NGK plug is hotter, BU8H or BUHW? here
For anyone is following the post.<br /><br />I contacted NGK and the said the BUHW is a colder spark plug and the BU8H has an actual heat rating which is hotter. [links]

Was just looking at that..can't decipher the BUHW temp. Is it colder or warmer than the BU8H.
Since cars with smaller engines may not see a performance upgrade, then the $60 you’d spend on iridium plugs doesn’t make sense. You would receive a similar outcome by going with whatever the manufacturer recommends. [links]
4. Some coatings can be brittle.
Iridium can be hard when it is correctly applied to spark plugs. The manufacturing process can also create brittleness in each layer because of the qualities of this metal. If that outcome occurs, then any bumps or scratches to the part could severely impact the performance of the unit. You’ll want to take extra care during the installation process to ensure that you don’t cause any unintended damage that could create problems with your future engine performance.
6. It requires less voltage than other designs.
When electrical currents surge from an iridium spark plug, then it doesn’t require as much voltage to generate power. That’s because of the unique design that includes a small electrode. Saving on energy during the start-up phase or while accelerating ensures that you have a reserve in place to manage the driving experience better. You’ll discover less lag happening when you press down on the pedal and fewer delays in the initial startup of the engine. here
It was first discovered in 1803 when there were insoluble impurities found in natural platinum. Smithson Tennant is the primary discoverer of the metal, and he named it after the rainbow because of the diverse colors of the salts.
Iridium is a chemical element that has the atomic number 77. It is known for its hardness, but it can also be quite brittle in its natural state. It is a transition metal that’s related to platinum, so it qualifies in some circles as a precious metal.
Your ignition system is pretty complex, and there are a number of important components that must work with one another to crank the engine and then keep it running. Your spark plugs are among the most important of these, and you have several of them (one per cylinder).
The engine has one spark plug per cylinder. Each spark plug is connected to a spark plug wire (in conventional and electronic ignitions). The wire runs from the top of the plug to the distributor, which is attached to the coil. However, if you have a distributor-less ignition, you have no spark plug wires. Rather, coil packs are used and the whole system is controlled by the computer. here
Spark plugs have a very simple yet essential job. They provide the spark necessary to ignite gasoline in the combustion chamber. Without working spark plugs, your engine will not run (there will be nothing to ignite the fuel and start the combustion process). Your car’s engine basically runs on a series of miniature, contained explosions. First, air and fuel are mixed in each cylinder. When the piston rises toward the top of the cylinder, the spark plug fires. Electricity arcs from the electrode to the tab, and the fuel and air mixture ignites. This creates pressure as the fuel is transformed into a gas (emissions), which pushes the piston back down and turns the engine. This cycle is repeated over and over again in each cylinder of your car. [links]
NGK V-Power spark plugs offer economical performance for nearly any automotive application—and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs.
Because of the V-Groove, the spark occurs at the edge of the center electrode—so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. More than a hundred models are available, both universal and application-specific; order the plugs designed for fitment on your vehicle. here
