LS 430 performance spark plugs ensure that your car's engine runs efficiently. They're designed to prevent deposits from fuel additives from building up on them, and they endure the extreme temperatures and pressure in the cylinder. The spark occurs only at the tip of the electrode, thanks to a ceramic insert, and after the voltage jumps the gap, it's conducted to the engine block, where it's grounded. When you shop for a Lexus LS430 spark plug set at AutoZone, you enjoy extra benefits such as our free engine diagnostic testing and battery testing when you visit your local store.
