I was looking into buying the NGK Iridium Spark Plugs, and was wondering if I had the right part number.
IFR7G-11KS
Is that correct?

 

Looks like it's the Iridium part that mimics the oem platinum plug design for longer mileage use. http://www.sparkplugs.com/more_info.asp?AA...30228&pid=15895

I'm running the NGK IX Iridium version which has a bit better performance design for the ground electrode, but you won't run them for nearly as long as the oem specs. I've never understood why anyone would run a plug for 100,000 miles, I don't mind changing mine out every 2-3 years if needed.
