Plug type at 90,000 miles ?
I’m about to have by X w/V10 in for the (gasp) 90,000 service interval (extended warranty)., the plugs will be changed, however, the dealer will try and put-in what they $make$ the most on… so.. please tell me the bottom line, (1) What plug type/brand should we be demanding. & (2) With my extended warranty going at 100,000, now’s the time to replace stuff, any thoughts on demanding greasable ball joint replacements and what else??
Thanks,
Steve
