Good tip on the plugs, they are going to be replaced really quick..
no worries mate. dont listen to the plug they tell you will work. the ones offered in auto places are too short for the NEW tigersharks by almost .5 inches. i found out the hard way. the 5325 are the ones to use. im running a .055 gap and will probly go to .060 gap
