When you look on ADVANCE AUTO's website there are multiple spark plugs listed that will work for the XF...is there really any advantage in going with the ones that cost a lot vs the $3 ones? The Bosch OE replacements are like $7.

Anyone ever have a Chrysler dealership change them? What did they charge?



At 72,000 miles the '07 still runs like a striped-*** ape........

Remember back in the old days when you had to do your points/plugs/valve adjustments on your VW every time you turned around!!
