I purchased plugs for my 2011 NGK 95843 ILKAR6C10 but I got
NGK 95843 ILKAR7C10. One point cooler. NGK no longer makes the first plug and
the official replacement is the colder plug. Anybody on the forum using the later type have any problems with colder specs. Should these colder plugs affect the normal operation of the 5.0 L engine?

I own a 09 XF w/4.2L SC engine and recently changed my sparkplugs to Denso IK16TT......I'm very pleased with their performance . This was the first sparkplug change for my XF ....it was at approximately 80,000 miles.
