Spark plugs where r the spark plugs on a 2003 mazda tribute located v6

You have to remove the intake (and the manifold) just to get to them. They are on the engine like every other car but access is trying because you can't even see them until you start removing the above items. If you still aren't sure where all of this is, follow the plug wires from the coil pack to the plugs. If it does not have wires, it will have individual coils on top of each plug. Unbolt each coil and pull it up. The plug is under it. On your V6, they should be located on the side.
This is very tricky on this vehicle. It is, of course, recommended to take it to a shop. Some special tools may be required.

Each plug has it's own coil. There will be 3 coils mounted on each side of the engine. They are located under the coils. You may have to remove the intake manifold to get to the rear plugs. Big job, may want to consider going to the dealer. Probably about a $450 repair(ouch).
