When do spark plug wires need to be replaced?

The lifespan of spark plug wires varies based on factors including the climate and driving habits, but they generally last about 60,000-100,00 miles. Periodic replacement helps maintain the engine’s performance.

What are signs spark plug wires should be replaced?

Common signs of wear can include a rough-running engine, possible misfires and even hard starting. Acceleration can be affected and fuel economy can decline. Visually, cracks or fraying of the wires are signs replacement is needed.

Are all spark plug wires the same?

No. Material composition and design can vary widely, resulting in varying levels of conductivity, durability and electrical interference suppression. GM Genuine Parts and ACDelco Gold Spark Plug Wires meet GM factory specifications.

Do battery cables need to be replaced often?

Generally, battery cables don't need periodic replacement, but they are subject to corrosion and other forces of wear that can affect their performance. This is especially true in climates of high humidity, where the roads are salted in the winter.

What are signs of the battery cables need to be replaced?

If loose connections are ruled out, hard starting, a failure to start and other intermittent electrical issues are common signs the battery cables should be checked for corrosion and other signs of wear.
