Thinking about changing my spark plugs because I'm not sure when the PO changed them. Is there any signs that they might need changing besides visually inspecting them. Also what size socket would I need to buy to get them out
also - please remember to put some antiseize into the threads on the new plugs before they go into the head and tighten them to either torque spec or so it's just starting to get snug - overtightening (and sometimes just regular tightening of them) them without antiseize might cause the aluminum head threads to seize to the steel threads on the plugs, and then dielectric grease up your coil boots before you put them back on. Just some word to the wise.
