Changed over to platinum plugs and cold starts on first turn of key. Iridium spark plugs are a little more expensive than the copper and platinum ones. Iridium spark plugs are typically the most expensive, ranging from $8 to $15 each. Iridium is harder, more durable, and more costly since you will be paying for the longer lifespan, and you will not have to replace the spark plugs as much as other options, like copper. These spark plugs are ideal for most cars that … The longer the plugs are in the engine, the harder they are to change and more likely they will seize up and break when replacement is necessary. Maintenance/Repairs. Learn more about quality spark plugs, find your car part, or find where to buy your auto part today. IX is … 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. Both types have the very same parts and construction, the only difference between iridium and platinum spark plugs is the metal used for the center electrode. Privacy Policy | Ad Choices | Terms of Use | See official rules for restrictions and complete contest details. I switched because of the cost and more importantly the length of time the plugs are installed. Under no circumstances will we be liable for any loss or damage caused by your reliance on any content. 2.Iridium plugs have a higher melting point than platinum plugs Iridium spark plugs When looking at iridium vs. platinum spark plugs, the sure bet is that iridium is the most durable and will last the longest. Without spark plugs, your car will not start. Aside from the very common copper spark plugs, there are two other options for most users; platinum and iridium plugs. They have a better performance … Those that do will have either a standard ground electrode design, usually in nickel alloy, or a solid platinum bar ground (similar to the Denso racing design) and a 0.4mm Iridium alloy centre electrode. Iridium has a much higher melting point than platinum; with values at around 4400 and 3200 degrees Fahrenheit respectively. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling. G-Power ®. To find out the recommended spark plugs for your specific vehicle, check your owner’s manual. A single platinum plug is much like a copper spark plug with a platinum disc welded to the center electrode; a double platinum spark plug has a platinum disc on both the center and side electrodes. I change my plugs every 50,000 and have had no problems. Around that rod is wrapped a ceramic insulator, and around that a metal case. The cost of the plug many not be such a significant argument, but the actual replacement can be an issue for some vehicles. Positive energy traveling through the wire from the coil jumps the gap between the tip of the wire and the metal case, which g… Platinum may be harder than copper, but iridium is the hardest among the three, and iridium spark plugs outlast platinum spark plugs by almost twice the mileage. Apparently in some cases iridium plugs are not always better. Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. A spark plug is essentially just a really thick wire with a short in it. The nickel-alloy outer material used in the copper spark plug isn’t as hard as other metals so it wears down more quickly with the high pressure and heat created in the cylinder of the engine. If you were to settle for copper or platinum spark plugs, then you might receive 50% of the lifespan when compared to iridium. Platinum vs. Iridium? This is the vital spark that starts the combustion process. Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. I have a 2001 Buick Park Ave. and replaced the Iridium spark plugs with Platinum plugs and see no difference in performance or mileage. Required fields are marked *, Notify me of followup comments via e-mail, May 23, 2011 • 5 comments. Iridium Spark Plugs.

Platinum plugs worked out better in this situation. If you are considering either as a replacement, the iridium plug is probably better since you do not have to change as often and you do not have to worry about the electrode prematurely eroding inside the combustion chamber and possibly leaving harmful deposits. Platinum may not be as durable as iridium, but it is a lot more durable than the standard copper spark plugs which tend to go bad very quickly. kescott1910. Iridium Spark Plugs have some significant advantages over spark plugs made using other metals. Although you will have to pay more money for iridium spark plugs, you will get what you pay for. 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). Platinum also handles high heat, enabling the spark plug to wear better. These metals also help extend the interval between spark plug changes and decrease the misfire rate. ©2020 DRiV Incorporated. durable as iridium spark plugs so having to change your spark plugs may be needed sooner Every plug in the Laser Series was designed for an OEM application. The majority of spark plugs feature a copper-core center electrode. Had everything in the motor diagnosed. {{lede.date | date:'dd-MMM-yyyy'}}{{lede.tags.length > 0 && lede.date ?

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? a. Iridium Spark Plug: Iridium is considered to be an extremely hard metallic element, as compared to platinum. Copper is an excellent conductor of electricity – better than any other type of material used in spark plugs – and also transfers heat faster. Platinum spark plugs The platinum plugs last longer than the copper plugs, but not as long as the iridium plugs. Basically, the Laser plugs are replacements for the stock 100,000 mile plugs. The use of metals like nickel alloy, platinum and iridium reduces the wear caused by high voltage sparks. But if you like changing plugs often, as new plugs would always perform better, using platinum plugs may not be a bad idea. 1.Iridium and platinum spark plugs have different center electrodes If you want a cheaper alternative to the iridium spark plugs, then go with the platinum spark plugs. I have a 2008 kia spectra with 134,500mi and had the plugs changed at 106,000mi. They have better performance and more complete combustion than platinum-tipped spark plugs. Iridium spark plugs and Platinum spark plugs are pretty similar in their overall design but they have one key difference which is the material the tip is made of. Since iridium is expensive, iridium spark plug manufacturers reduce the diameter of the central electrode to 0.4 mm. Iridium-tipped spark plugs offer better power, more complete combustion that leads to smooth-running engines, and a longer lifespan than copper/nickel plugs. A platinum disc is melted on the tip, which makes the plugs resistant to deposits. Iridium Spark Plugs You must have guessed that iridium is harder than platinum. Was advised Iridium plugs were better, so had those put in. Platinum spark plugs come in two varieties - single and double platinum.

Iridium plugs are even longer lasting than platinum. Platinum spark plugs last anywhere from 20,000 miles to 60,000 miles before needing to be replaced. A standard spark plug typically features a nickel-alloy outer material fused to the copper-core electrodes. That’s why the cost of this product eventually balances itself out over time. Due to this short lifespan, most copper spark plugs need to be changed every 20,000 miles. Platinum plugs deliver enhanced performance and fuel efficiency compared to copper plugs, but for a considerably cheaper price than iridium spark plugs. Your email address will not be published. The higher melting point means that iridium plugs can be made hotter than platinum plugs. All rights reserved. 3.Iridium plugs are stronger than platinum plugs Platinum plugs have harder electrodes and therefore they last longer with less change in the spark plug gap. You’ll receive more corrosion resistance with iridium spark plugs. Iridium spark plugs are quite consistent and wear-resistant. In reality, copper has the best performance of … Car is 2008 kia spectra, synthetic oil that’s changed every 5 to 6 thousand miles, coil paks replaced at 106k new, new plug wires at 106k. If your owner’s manual specifies iridium spark plugs, don’t downgrade to platinum spark plugs or copper spark plugs; if you downgrade, you run the risk of poor engine performance. 8.
