My Vanagon runs noticeably better on Bosch +4 Platinum plugs than on
standard Bosch plugs.  I got about 45K out of my last set.  I pulled them
when they fouled horribly last summer at about 5000 feet on the Blue Ridge
parkway.  I was surprised at first, but then I remembered that I've them in
my van for 2 years.
