Product Details

The Champion 841-1 Copper Plus Spark Plug is designed specifically for small engines found in lawn mowers, garden equipment, and other outdoor power equipment. This non-resistor spark plug features a reliable copper core electrode that provides excellent conductivity and heat dissipation for consistent ignition performance.

Key Specifications:

  • Heat Range: J8C (Champion type)
  • Thread Size: 14mm
  • Thread Reach: 0.375 inches (3/8")
  • Seat Type: Gasket seat
  • Electrode Material: Nickel copper alloy
  • Pre-Gap Range: 0.027 - 0.033 inches
  • Non-resistor design for magneto ignition systems

The copper core construction ensures superior thermal conductivity, helping to prevent overheating and pre-ignition in high-performance small engines. The gasket seat design provides a secure seal without requiring torque specifications as critical as tapered seat plugs. This spark plug is ideal for applications where a non-resistor plug is specified by the equipment manufacturer, commonly found in older lawn and garden equipment with magneto ignition systems.

Best price on a timken wheel bearing I could find. I will be doing business with them again.

Great prices and items were shipped very quickly. I will definitely buy from Autoplicity again.

I couldn't find this part anywhere! That's until I found Autoplicity! Thanks Guys!

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Best price on internet. Local dealer wanted 325 dollars more for exact item. Great place to do business.

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier
