Many people have spent hundreds of dollars with a mechanic trying to diagnose an engine performance or fuel mileage problem, only to learn that the culprit was bad spark plug wires.
Today’s high under hood temperatures are tough on spark plug wire insulation and the high-output ignitions found on newer vehicles have little tolerance for bad wires. Spark energy will take the path of least resistance and arc to whatever metal object is closest. Wires simply wear out, and a new set of wires may make a huge difference in how your vehicle performs.
Advance Auto Parts has a complete line of spark plug wires custom fit for your application.
Warning signs that your spark plug wires may need to be replaced:
Hard starting. An erratic idle. Hesitation. Bad fuel mileage. These are all signs that your wires may be worn out and in need of replacement. Wires are a "wear item," meaning that they wear out over time and need to be replaced, just like tires and brake pads.
Many engine problems can be easily fixed by an affordable set of spark wires, available at Advance Auto Parts – along with a full line of other quality auto parts.
