Get rid of those friggin crampion plugs!
I pulled mine and replaced with Autolite 5224 platimums, I was getting
12.5-13 mpg and couldnt do any better around town. Now I am getting 14-15
mpg with no change in my driving. Yup, After 3 tanks of gas I am still
hitting 150 miles at the half tank mark!
PLUS the factory plugs, at least on mine, did not have any antisieze on them!
 W/ aluminum heads, you should use hi temp copper antisieze on the plug
threads.
Just thought I'd pass this on!
