OEM is usually the best way to go. My 94 Chrysler LHS had an occasional misfire at highway speeds when under load such as going up hill. I know cars and figured the wires were the most likely culprit. They were. These wires were an exact fit and of much better quality than what was currently in the vehicle. What was the previous owner thinking. I am very satisfied with the product and would purchase them again. With only 88K on the odometer these wires will last for many years.
