Just a note
i put one of those "Iridium" NGK plugs into mine
WOW what a differance !! im not a big believer in those fancy plugs but this made a BIG change !
Rubi's come out with platinum plugs
and the foremans come out with those STUPID v-groove plugs
change it to the Iridium and enjoy better throttle response, better cold starting, and what not
i actually had to lower my idle !!
