    Automaker-supplied spark plugs are only good enough to get your Kia Optima’s engine up and running, while being designed and manufactured with only one sole purpose in mind - to be as inexpensive as possible. And that is precisely why there are so many performance spark plugs offered by so many different manufacturers in the aftermarket. These plugs will arc up the air-and-fuel mixture to the utmost, while promoting more complete and thorough combustion. This, in itself, will result in horsepower and torque gains for your Kia Optima’s engine. To add to all that, your engine’s harmful carbon monoxide gas emissions will be lower.

    Performance spark plugs are offered in a wide range of electrode materials, which include platinum, silver, iridium, nickel, and other noble metals that ensure consistent performance over a longer service life. And of course, performance spark plugs come with a variety of other features which differ them from original-equipment plugs, including thicker electrical insulators, different numbers of ground electrodes, heat ranges, and so on. These plugs will surely keep your auto’s cylinders firing run after run, so you can shop with confidence!
