• Description:

  A spark plug (22401AA65A) ignites the air-fuel mixture to ensure your Subaru vehicle's quick start. The equipment includes the terminal nut on one end and a threaded shaft that houses the insulator and center electrode on the other side. This unit then attaches to the engine's cylinder head.
  Aside from creating an arc of electricity to start your engine, the spark plug also removes unnecessary heat from the combustion engine and transfers it to the cooling system. Hence, it regulates the engine's temperature. Symptoms of a failing unit include slow acceleration and reduced fuel economy. Should you notice these problems, it is advisable to inspect the equipment before it causes irreversible damage.
  Consider choosing an OEM Subaru spark plug since it only includes quality materials that can resist extreme temperatures and high electric currents. More importantly, a genuine auto part features 100% compatibility with your car, eliminating possible engine issues.
