Re: Changing Your Plugs in 2005 Mazda6
What the heck! Are you Stupid? Take a Socket Wrench and plug socket and turn left to remove the plugs... turn right to tighten. Any moron knows that!!
As for what has to be removed... remove it and replace it as appropriate; don't forget gaskets. Or take it to the Mazda Dealer (Walzer), 98 miles from your house you dumb jerk, they'll do it for $365.00 + Tax that's $386.90; don't forget to include additional cost of shop supplies, waste disposal plus the 196+ miles you'll drive; so through in another $3.50 per gallon of gas... say 7 gallons; you're looking at about $428.00 dollars for the plug change.
As for asking here what's required to change out plugs, what the heck do you think this is, some kind of helpful web site run by mechanics. If the official Mazda Mechanics Manual does not show it, what the heck makes you think anyone here can provide answers to you questions? Go away and die you dumb old man.
