My sparks plugs in my drive around corolla are stuck. I bent my spark plug tool trying to get them out. When my mate bored the car he said the needed replaced and had a hard time getting them out. He swears he did them only finger tight. While I know I will get them out, I dont understand why there tighten up.
Thanks for the responses. Havent tried again to get the out yet until i get hold of a spark plug socket for a ratchet. But the suggestions could come in handy
