Hi had my 95 Intrepid 3.5 liter towed to a shop and was quoted a price of $550 to replace battery, plug wires, and spark plugs. Does anyone know if you need to unhook motor mounts to get to the rear plugs to replace them? Is it a bear to do? Any special tools needed? Thanks

 

I did the plugs and wires on my 97 3.5 with no special tools, but it was tricky and took a while.

 

take off the upper intake it will take you about 15 minutes after that it is cake

 

You don't need to remove the intake. Just be patient and take your time running one wire at a time.
