A Intro to SPARK PLUGS Part 2
September 27, 2017
- Double Platinum Spark Plugs
The double platinum-tipped spark plugs are comprised of small platinum discs at the firing surfaces of both the central and side electrodes.One popular variation of the double platinum spark plug is known as “fine wine”which features one or more platinum discs at its core. The double platinum dramatically increases the longevity of the spark plug such that platinum materials can effectively resist quick deterioration. In fact, it may last up to 100,000 miles plug change. Aside from longevity, double platinum spark plugs also enable improved engine performance.
- Iridium Spark Plugs
Iridium is one of the rarest element. It is tougher than platinum and will easily beat copper when it comes to longevity. Just like platinum it has great resistance to wear and erosion and may even sometimes outlast platinum in this matter. They are designed to conduct electric energy better and provide enhanced power and more unabridged combustion that leads to smooth-running engine performance. Iridium spark plugs typically cost more than copper and platinum-tipped spark plugs.
TIPS ABOUT SPARK PLUGS
Iridium spark plugs will normally not require gapping adjustment since iridium materials themselves may be easily damaged during the gapping process. Gapping is the process of adjusting the distance in between the plug tip where electricity comes from and the curved conducting electrode. This is done by bending the electrode using a special gap tool. Proper gapping can maximize power, reduces fuel consumption, promotes smoother engine performance and increases the life span of your spark plug.
All in all, regardless of the type of spark plug you opt to use, its heat range is crucial. Plugs with higher heat range adapts more to more difficult driving conditions and style.
