The CHAMPION J17LM / 845-1 Small Engine Spark Plug is an essential component for optimizing the performance of your small engine. Ideal for a range of applications, the J17LM spark plug features a durable construction tailored for small engines.
These are my spare spark plugs. I have a 50 year old plus ice auger that has been in storage for over 22 years. I put in fresh fuel and on the 4th pull it started. I could not believe it. The 50 year old manual called for this Champion spark plug as the replacement spark plug and it is still available today. Anything used 50 + years ago and still available today I consider it to be a great product. The original spark plug is still in the auger.
