What about platinum spark plugs, I can say that it is also a good spark, especially when a spark plug has double platinum. Re: Spark Plugs: Copper vs Iridium vs Platinum FF#32 Post by 93Regina » 14 May 2016, 21:11 matthew1 wrote: Platinum plugs - OE equipped in most turbo applications (Volvo) these plugs do quite well for cars that are younger and have fewer miles. Platinum, yttrium and iridium spark plugs are more expensive than copper spark plugs, but these premium coatings provide much better wear resistance. Though better than platinum in these respects, it is very expensive, and at higher temperatures it oxidizes, thus rendering pure iridium as an expensively poor choice for spark plug construction. Electrically speaking, the copper type plugs, such as the ones from Autolight, convey the power better than the irridium or platinum plugs. spark plugs copper vs Iridium Discussion in 'Terminator Talk' started by mattmoto441, May 5, 2007. It is high-performance, spark plugs with a central iridium electrode, which consist of durable alloy. Both platinum and iridium will last you long, but both of these metals are inferior conductors compared to something like copper. The spark plugs like iridium or platinum are not just an aftermarket upgrade anymore. Reason being there has been a long discussion on my Focus forum about swapping out the Motorcraft platinum for copper due to greater conduction of the spark. Pros and Cons: Iridium vs Platinum Spark Plug; 7 Symptoms of a Bad Spark Plug in Your Car; Copper Spark Plugs. The fine wire spark plugs require less voltage to fire compared to the larger copper electrode, which makes things easier for the ignition system and allows for an increased plug gap to fatten up the spark … Some plugs have a higher platinum content than others, and may have both electrodes platinum tipped, as opposed to one. Platinum spark plugs have a long service life and eliminate the probability of a waste charge. 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. Various metal types are used by NGK for ground electrodes and center electrodes. Platinum has good longevity and the worst performance. Also, it has a nickel alloy-based central electrode. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. “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. For many years, spark plug manufacturers favored platinum for their long life and performance plugs due to its high melting point. Messages: 1,697. But as far as I know, Toyota Corolla still comes with regular copper plugs. Copyright © 2003 - 2020 PakWheels (Pvt) Ltd. - All Rights Reserved.

Joined: Jun 11, 2002 Location: In those cases, copper spark plugs are considered to have a high spark plug performance. Copper $4/30k. Platinum lasts longer but copper conducts better and the recommendation was to try those and open the gap 0.50 to 0.55. If the manual demands to use copper spark plugs, do not use platinum or iridium spark plugs. 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. Due to its soft nature and low melting point, using copper as an outer electrode material would result in a plug that lasted only minutes. Both are iridium spark plugs and have a long lifespan. A spark plug is essentially just a really thick wire with a short in it. Often specified as original equipment, NGK Laser Iridium spark plugs are the best combination of performance and longevity. 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. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. The main reason why parts manufacturers moved to materials like iridium or platinum is the longevity of the electrodes. Positive energy traveling through the wire from the coil jumps the gap between the tip of the wire and the metal case, which g… Longevity: 55-75 thousand miles. Iridium has good longevity and a performance that is decent, which is why iridium plugs tend to be more expensive than any other type. However, increasingly strenuous engine conditions, and the creation of smaller electrodes and longer life plugs required harder and stronger metals. Adjustable vs. fixed gap.

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. For a very long time, only copper spark plugs were available. These spark plugs have a small center electrode which means they use less voltage to generate the electric current. Iridium spark plugs are the best plugs because of their durability but are more expensive than platinum and copper spark plugs. Single Platinum Spark Plugs. In short, the answer is no.
