So I know this has been done to death but....
Has anyone run a BR9ECS - 5 in an 08 XP ?
Gap is a bit tighter then BR9ECS, but local LORDCO said the -5 has replaced the regular BR9ECS ?
Plugs used to be # 4771, was told NGK replaced that number with #6669 (which is now .5mm gap)
Just found out std BR9ECS with .8mm gap is now #4667
