This particular model is designed with advanced technology and high-quality materials to ensure long-lasting performance even under extreme conditions. It has a nickel-plated shell for corrosion resistance and a platinum-to-platinum firing system for consistent sparks.

Not only does Autolite 458 spark plug provide reliable performance, but it also helps improve fuel efficiency and reduce emissions. With its precise gap design and efficient combustion, this spark plug ensures that fuel is burned more efficiently, resulting in better mileage and lower emissions.
