Champion Copper Plus Spark Plugs

Weight: 1.05

Features of Spark Plugs:
  • Patented Resistor: High voltage semi conductor resistor for maximum EMI suppression, proven to be the most durable in the industry. Certified compatibility for use in modern computer controlled, distributorless ignition systems
  • Five Rib Near Diamond Hard Insulator: Patented, zirconia toughened alumina insulator for near diamond hardness. Five rib design increases strength 35% while insuring against ignition flashover and securing the plug boot seal
  • Rust Resistant Shell Finish: Zinc plated shell resulting in maximum corrosion resistance. Also serves as thread lubricant to aid in prevention of thread seizure
  • Triple Seal Assembly: Use of upper and lower metal gasket along with sillment seal provides strongest yet least stressful seal known to the industry. Eliminates spark plug failure due to heat or mechanical induced stress
  • Copper Core Center Electrode: Provides maximum heat dissipation and durability
  • Precision Rolled Threads: Conforms exactly to I.S.O. and S.A.E. standards as specified by all engine manufacturers, resulting in easy installation and removal
