On a 1994 3.5 engine, the plugs are at the bottom of deep wells. The spark plug cables enter the top of the engine with a rubber plug that conceals the hole. Pulling this plug out reveals a rubber stalk several inches long that snaps on to the top of the plug at the bottom of the hole. Use a spark plug socket with a rubber insert that catches the plug to remove the plugs. You can use a piece of hose to thread the new ones so you don't misalign the threads. Don't tighten the plugs too tight. Firm is good but don't crank them in with all your strength. Also--if you are replacing the cables you need to buy a set that fits the year, make, and engine of your car.

I'm just now learning about spark plugs, but I read that the ignition system may not recognize the voltage used in the iridium plugs. They require less voltage than platinum to start the engine.

All freeze plugs for engines are below the spark plug side of the engine. They are small round plugs that will pop out if engine freezes in the winter time. This will cause water leaks if they go bad anytime.
