These can serve as a gentle reminder that new spark plugs should be the same, if not similar, model as what your vehicle was originally equipped with. [1][2][3] In marine engines, the shell of the spark plug is often a double-dipped, zinc-chromate coated metal.[4]. The outer surface is ribbed to provide grip for the spark plug boot and to simultaneously add protection from spark flashover (crossfire). Cold Spark Plug: For high-performance engines that run hot by default, using a hot spark plug will cause pre-ignition. Under no circumstances should you avoid the advice of your local mechanic or small engine repair professional. Use the penetrating oil to spray it down the barrel of the spark plugs. This is claimed to improve ignition by maximising the exposure of the fuel-air mixture to the spark in every cylinder. The reviews provided at Best Home Gear are Never Sponsored by manufacturers, and we always remain Unbiased in our approach to all Product Reviews. 3) If you havent changed your spark plugs in 2 years or more, your problem will likely be a bad spark plug.
