Is is better t stick with the OEM copper plugs in my 2010 Dodge Ram 1500 (5.7 V8) or go with a platinum or possibly iridium plug? On the 4.0, the ignition is designed to use a copper plug. However, the porcelain on the Denso Iridiums is slightly weaker than the porcelain found on the majority of copper plugs, so if you have detonation, the Denso's are more likely to break. Answer Save. Copper Spark Plugs. The nickel alloy is also softer than platinum or iridium, so the sharp edge firing you get right out of the box tends to wear out quickly. They have been working real for me. However, lifespan is by a wide margin the best when compared with copper. That’s because copper has the lowest melting point of all the currently available spark plug materials (copper melts at 1,983 degrees F, yttrium at 2,779 degrees, platinum at 3,222 degrees and iridium at 4,229 degrees). I'm no engineer, but if there was a significant benefit to using a different plug the manufacturer would have done so for you. It has a very large diameter compared to other spark plugs on the market. Iridium spark plugs made of significantly less conductive material. Old copper plugs use a nickel electrode. This can be an advantage in certain situations. I'm riding a RoyalEnfield Bullet 500 (Cruiser bike). If the Laser iridium have indeed only one iridium (or platinium + iridium) pointy electrode, I can see the Ruthenium lasting longer. One of the mechanics asked me to change my Iridium Sparkplugs, which is the stock one to Platinum as it gives better mileage and performance. In 2013 there is two listings for plugs, older part number SPLZFR5C11 which is used in older than 2013 as well, and the newer part number SP143877AA which is 2013 and newer.

I know the Iridium last a long time, but that really isn't an issue, plugs are cheap and easy to change. Platinum has good longevity and the worst performance. The main reason why parts manufacturers moved to materials like iridium or platinum is the longevity of the electrodes. All dual precious metal plugs are designed to provide maximum longevity. Copper refers to the main internal electrode material. Copper spark plugs are better for old (up to 1980's) cars with low voltage distributor based on ignition systems. Depending on application, iridium plugs can even approach the lifespan of some platinum ones. I should try the Autolites after all. Many, many years ago, it was not the case that they … Some copper spark plugs use different shapes and configurations to produce similar results for a fraction of the cost. To think a spark plugs is a spark plug is like saying "motor oil is motor oil" Technology advancements can occur at every level. It's a bonus that they last 100,000 miles. On the other hand, copper spark plugs will wear out at around 35,000 kilometers (give or take few thousand kilometers). 3. Gap is the same, form factor too. Choosing Iridium spark plugs over Platinum ones would be the ultimate choice. Plugs with platinum or iridium tips have much wider heat ranges. Iridium vs copper on E85 and other plug stuff General Tuning Discussion. Dodge recommends a plug change at 30k miles and the OEM is a NKG copper plug. The quenching effect has been decreased by forming the electrode into a double needle shape. So about spark plugs, conventional oem recommendations usually say no platinum or iridium for Re85, do you know whats behind this? Just bought what the hood said to.

The iridium plugs are a "cooler" temp plug, so when super charged, they resist pre detonation. A spark plug’s reach is defined as the length of the threads. ... Iridium spark plugs also have lower voltage requirements, meaning they perform better when … Let’s go over their pros and cons now. A single platinum spark plug is basically styled after a copper spark plug with a platinum disc welded to the tip of the center electrode.Since platinum is harder than nickel alloy, it holds its sharp edge for as long as 100,000 miles. 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. I doubt the dealer changed them before selling the LJ. The metal in a spark plug has a single purpose: to channel the electrical energy through the spark plug. RE is looking to save money, so platinum spark plugs will never be worth the small performance gain. ... Electrically speaking, the copper type plugs, such as the ones from Autolight, convey the power better than the irridium or platinum … Iridium spark plugs are not the best in terms of performance but nothing can beat their longevity. I recently changed the plugs on my Ford Ranger with the original plugs in it at 139,000 miles. Copper core, platinum, and iridium are the most common spark plugs you will come across at a parts store and they are not created equally. But, while it is fairly inexpensive compared to comparably conductive materials like silver, copper is also extremely susceptible to heat damage and corrosion. They were iridium. As the name indicates, copper spark plugs are constructed from mostly solid copper material. I always think bad upstream O2 sensor when an engine problem like yours only happens once the engine starts to warm up. ... Pros and Cons: Iridium vs Platinum Spark Plug; 7 Symptoms of a Bad Spark Plug in Your Car; Copper Spark Plugs.

Between platinum and iridium plugs, iridium is considered a better option than the platinum, but it still doesn’t match copper’s conductivity. 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 a little. Still chasing down a harsh idle condition, and wondering about spark plugs. The truth is that these fine-wire spark plugs are an outstanding choice for a performance street car. 1.
