火星塞也是會被電吃掉的

Denso 銥合金？
我勸你還是時間到就換不要拖。身邊已經有幾個案例是拖太久結果針頭飛出來刮傷汽缸造成吃機油的了。

銥合金火星塞的設計是增加點火效率，不是用來撐的。傳統火星塞最能撐。

這點我有點疑問喔
如果沒記錯, NGK和Denso的銥合金火星塞印象中都號稱可以撐很久的
Denso Iridium系列有四種(太久沒看, 剛剛發現又多了Iridium Plus)
能撐多久可能還是要看是用哪一種...

傳統碳電極的好像是50000km

Q. How long will Iridium Last?
A. Iridium use represents the most significant technological advance in automotive spark plug manufacturing, since platinum was introduced in the early eighties. As vehicle manufacturers produce increasingly complex and efficient automobiles, there is a greater need for long-life plugs that can tolerate leaner fuel mixtures and improved combustion processes. DENSO has responded to this need by developing its Iridium alloy, originally for OE applications. For example, many newer Lexus’ and Toyota models carry an ultra long-life Iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service. DENSO Iridium Power plugs, with their .4mm center electrode, have been developed for performance applications. Because gradual wear will “round-off” firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, DENSO advises replacement after 30,000 miles.

Denso Iridium Long Life是0.7mm(直徑)
Iridium Power/Racing是 0.4mm
Iridium Touch ???不知道
NGK IX是0.6mm
上面應該是說使用ultra long  life variation可以到120000mile才換
(這個Denso有誤導的嫌疑....)
使用0.4mm的30000mile
NGK的FAQ就比較中肯(模糊?), 他們就沒有給時間


Denso大概只能拿Toyota or Lexus....兩個根本是同公司的

我自己裝了Iridium Power用了80000km了...還想撐
