Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. It does not constitute any contractual term, representation or warranty. Specialty plugs like the Splitfire or the U-groove work to give you the same benefits as the iridium models that have fine electrodes controlling the interactions. Denso's ultra fine 0.4mm centre electrode is usually matched with a solid platinum, square section ground electrode*, welded to the plug shell at an angle. A traditional ground electrode is teamed with Denso's ultra fine 0.4mm Iridium alloy centre electrode to provide excellent performance. This is particularly true in countries with gasoline of bad quality (poor octane rating). If installed in a regular engine, they would likely last longer than most people keep their car (barring any motor problems that can cause premature plug death). Iridium is harder than platinum, and in most cases, iridium spark plugs last about 25 percent longer than comparable platinum spark plugs.

Pure Iridium is difficult to work with, very brittle and does not have great electrical conductivity hence alloys are used to give the best combination of these properties. Dec … Not all NGK racing plugs incorporate an Iridium centre electrode. *Note that some race parts do not have a traditional ground electrode, these are known as surface discharge plugs and remove the risk of damage to the ground electrode (as there isn't one!). That’s why it is such an expensive product when purchasing spark plugs coated with it. This can be an advantage in certain situations. Prices may be subject to change without notice. The majority of engines and vehicles almost always benefit from the replacement of a standard product. IRIDIUM SPARK PLUGS.
