3 coils, 3 plug wires, 6 spark plugs and a complete timing componet KIT w/water pump. That is a good deal (MAYBE???) IF it includes installing ALL componets correctly! You may want to ask! All 3 coils MAY not be needed.
some things are to good to be true.sounds to cheap to me. what about the water pump?
6 spark plugs and 6 wires.timing belt should includes water pump and belt tensioner.it's a good deal
