X2 do the wires and plugs yourself. A shop is going to charge a lot for those since the book tells them to remove the upper manifold etc. You do not have to do that if doing it yourself. The plugs are easy. The wires are tricky, but not too bad. The coil packs for the wires is behind the engine, right up agaist the firewall. There is a thread on here about how to change the wires (without removing the manifold). X2 on the 8mm wires.
