How Often to Change Your Spark Plugs

The electricity used to ignite the air and fuel mixture in your engine is conducted by your spark plugs. They’re a small, inexpensive part that’s easy to overlook. Many of our North Charleston and Mount Pleasant drivers don’t have them replaced until their vehicle is on the fritz. If you’ve been curious as to how often to change your spark plugs, then let the Rick Hendrick Chevrolet parts department answer your question in depth before you have yours inspected.

• You’ve noticed your car is slower to accelerate
• Your car is burning through gas faster
