Frequently Asked Questions (FAQs)
1. Do platinum spark plugs make a difference?
Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs. 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.
2. What is the main disadvantage of platinum spark plugs?
Single platinum spark plugs feature a platinum disc welded on the center electrode, while double platinum spark plugs have platinum discs on the center and side electrodes. The only drawback of platinum is that it's less conductive than copper, so it is inferior to the latter when it comes to performance.
3. Do platinum spark plugs increase performance?
Platinum plugs deliver enhanced performance and fuel efficiency compared to copper plugs, but for a considerably cheaper price than iridium spark plugs. Much like iridium plugs, platinum spark plugs operate at a lower temperature than copper spark plugs. They can also last up to twice as long as basic copper plugs.
4. Which is better copper or platinum spark plugs?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
