Some Lexus owners are swapping out their factory iridium tipped spark plugs for Denso Iridium Power plugs (http://www.denso.co.jp/PLUG/iridium-e/). Has anybody done this?
I'm just curious. I definitely do NOT plan on doing this but was wondering if anybody did and thought they were better like the Lexus owners rave about. A major con is their 4mm tip wears out after 30K miles while the normal ones last 100K miles. But a major pro according to the Denso site the smaller tip lowers the voltage needed to start a spark.
