NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency. u814ZN}

白金呢？？？

单点白金的可以便宜100多元，但双白金或三白金的与铱金的差不多价钱． f4 Q( 1(C  
白金的说是能用5万公里（一倍）以上． -Un=TX  
我以为大家的梦想都是0.6mm的ＮＧＫ铱金！其实还有0.4mm的铱金不敢介绍给大家． ywEDy|Wn$~  
好吧，也找以下白金的． 2m\m/O

描述： /WV7gO&L1  
NGK VX series are manufactured with performance in mind. The center electrode is platinum fine wire(0.8mm) for both long life and better performance. A fine wire center electrode requires less voltage thus creating a stronger spark from your current ignition system. A tapered cut ground electrode improves ignitability by allowing for larger growth of the flame kernel.

团购的请注明要白金，ＶＸ白金，还是铱金，最少两套，可以一套白金加一套铱金． UP1?5Q=H]Q

昨晚看到一位三菱Ｖ３３的网友说，换了铱金火塞后每百公里油耗降了１升，如果ＦＬＫ能省半升（保守），火塞的寿命在４万公里（保守），每公升油３元（９０＃），最少能省６００元，说不定能省１５００元呢！

我想只要一套铱金的行不行（325元）？如果不行就要两套白金的（380元）。
