when i changed my plugs a couple years ago one of the boots stayed in the head. it was a bear to get out and i used a mirror and a pick to pull it out in pieces. i bought a couple of new ones from subaruparts so now i have a spare.when i put the new boot on i used a fair amount a dielectric grease to hopefully prevent this again.i put grease on all the others as well. hope this helps.
