Don't ever use bosche plugs in anything, I have seen tons of bad ones out of the box, last week I fixed two dakotas with misfires after someone did a tune up, a 4.7 and a 5.2 both had new bosche plugs, regular and plat+4. A quick swap to NGK fixes em for good.


I am not causing global warming, I am just trying to hold off a impending Ice Age!
