hmmmmm. VERY interesting. my bus also changed in average mpg
after i changed to the triple-prong Bosch plugs. in the 70,000
miles that i've been using the Bosch plugs, my overall average
mpg rose from 19.1 to 20.0 ... and i did NOT change anything else
(i had been using Champion spark plugs). and i haven't changed my
style or amount of driving in those 70K miles. i suspected the
plugs were better, but don't really have any 'proof'.
interesting.
