Product Details

The Champion 931M Copper Plus spark plug is engineered specifically for small engines, delivering reliable ignition and consistent performance for lawn mowers, snow blowers, generators, and other outdoor power equipment. This plug features Champion's proven copper core electrode design that provides superior conductivity and heat dissipation for dependable starts and smooth operation.

Key Features:

  • Copper core electrode maximizes conductivity and extends plug life
  • Triple-coated shell provides excellent corrosion resistance in harsh outdoor conditions
  • Triple-seal assembly prevents combustion gas leakage for reliable performance
  • Precision-rolled threads ensure proper fit and easy installation
  • RFI suppression protects sensitive electronic components
  • Resists fouling and overheating under varying load conditions
  • Type QL82C designation for easy cross-reference

Champion spark plugs are designed to meet or exceed OEM specifications, making them an ideal replacement choice for maintaining optimal small engine performance. The copper core design ensures efficient heat transfer away from the firing tip, reducing the risk of pre-ignition and engine damage.

Copper Plus Small Engine

Excellent selection, great prices, and fast shipping. I am very satisfied.

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

Great price on the gas jugs

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.

"Customer service was very helpful, very good prices. On its way the next day."
