Iridium Spark Plugs When it comes to handling heat, iridium is the best among the three, including copper. The main reason why parts manufacturers moved to materials like iridium or platinum is the longevity of the electrodes. In a recent 1k+hp 2jz dyno the copper plugs just did not ignite with re85 and high boost levels, but denso iridiums did the trick. Iridium is a better conductor and lasts longer. But it will die in maybe less than half the age of these expensive plugs. Platinum’s high melting point prevents it from wearing as quickly as a traditional plug. A spark … But as far as I know, Toyota Corolla still comes with regular copper plugs. Iridium is 6x harder and 8x stronger than platinum, has a melting point 1,200°(F) higher, and conducts electricity better. For many years, spark plug manufacturers favored platinum for their long life and performance plugs due to its high melting point. Various metal types are used by NGK for ground electrodes and center electrodes. These newer plugs are sold for as much as Rs1200 a piece (depending on type and brand). Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Depending on application, iridium plugs can even approach the lifespan of some platinum ones. This means if durability is a quality that you’re looking for the most, then you won’t get it from platinum spark plugs. Joined: Jun 11, 2002 Location: “As an example, an Autolite copper 105 versus an XP Iridium 105 will have identical ceramic temperatures and the carbon burn off will be the same,” says Reeves. Positive energy traveling through the wire from the coil jumps the gap between the tip of the wire and the metal case, which g… On the 4.0, the ignition is designed to use a copper plug. So making coils go out is highly doubtful. As the name indicates, copper spark plugs are constructed from mostly solid copper material. Single platinum spark plugs—a step up from copper spark plugs In short, the answer is no. Such as copper vs platinum vs iridium. In reality, copper has the best performance of all three and the worst longevity. Platinum spark plugs have a long service life and eliminate the probability of a waste charge. The main reason why parts manufacturers moved to materials like iridium or platinum is the longevity of the electrodes. Why? With a full line of spark plugs, coils, and wire sets, NGK covers 95% of import and domestic vehicles on the market. Both platinum and iridium will last you long, but both of these metals are inferior conductors compared to something like copper. With most makers you can expect some 50-60 000 miles out of them. However, when properly blended with other precious metals such as yttria, rhodium or platinum, you can enhance their advantages with the superior strength and hardness of iridium. The price point of an iridium plug is usually equitable to its iridium content. If the manual demands to use copper spark plugs, do not use platinum or iridium spark plugs. However, gold is also a very soft metal, therefore the gold alloy is mixed with harder metals, such as palladium, to form a premium fine wire performance plug with increased ignitability and durability. A platinum or iridium spark plug will last you something like 80,000 to 100,000 kilometers. Single Platinum Spark Plugs.

At the core of any spark plug is an approximately 3-inch long metal rod; one end of that rod plugs into the ignition coil via the plug wire or boot and the other is exposed. On the other hand, copper spark plugs will wear out at around 35,000 kilometers (give or take few thousand kilometers). It is high-performance, spark plugs with a central iridium electrode, which consist of durable alloy. Some plugs have a higher platinum content than others, and may have both electrodes platinum tipped, as opposed to one. As for the 2.7, the ignition system is desigened to work best with the iridium plugs. They likely will not perform or last as long as the plugs with a higher iridium content. 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. Iridium $8/60k. Discussion Starter • #1 • Nov 7, 2011. Other materials are harder, stronger, have a lower electrical resistance and a higher melting point, and are therefore used to enhance nickel electrodes and prolong a plugs life in high performance designs. Longevity: 75-80 thousand miles. Some copper spark plugs use different shapes and configurations to produce similar results for a fraction of the cost. Some plugs include a coating or pad of precious metals to extend plug life. Both types of plugs have their pros and cons. But as a general rule of thumb, all spark plugs utilize a copper core. While copper is a good conductor of heat, the plugs wear quickly and must be replaced every 20,000 miles. Copper is a great electrical conductor with low resistance. The strength, hardness and high melting point of iridium makes it very well suited for a fine wire plug and ultra long life spark plugs. Some coatings can be brittle. But the trade-off here is the conductivity of the spark plugs. Adjustable vs. fixed gap.
