...and for the record...here's the advice about plugs that was on the thread you asked THERE YESTERDAY about plugs...
DATED 05/03/13...appearing on page one of that thread where your question posted on page 2....
"The Iridium IX like the Denso Iridium power are "power" plugs meaning they put out a slightly stronger spark at the expense of shorter life because they do not have a platinum ground strap (making it dual precious metal). They also have an ultra fine wire versus the fine wire of the others.
The Iridium IX are about 2-3 dollars per plug cheaper depending on the source.
I have used them before and noticed zero difference versus Denso Iridium Long Life.
For the price they are good. But if you plan to keep the plugs for 120K then go with Denso Iridium Long Life or NGK Laser Iridium."
This seems quite clear and to the point.
