Sold in sets of 6. If you want 6 spark plugs, order a quantity of 1. If you order a quantity of 6, you will receive 36 spark plugs. 

The Autolite 103 plugs are the ZZP team's preferred plug. They need to be changed out more often than the NGKs but performance and KR reduction is excellent. The racing version of the 103's has a back cut electrode and they feature nickel plating. 

  • Mixture of nickel and copper-glass seal that bonds the insulator, terminal post and center electrode together, assuring full voltage
  • Chromium-nickel alloy ground electrode resists gap erosion
  • Copper-core center electrode sheathed in high chromium-nickel alloy for superior heat dissipation and durability
  • Longer insulator nose provides a longer path to control fouling deposits

104 autolite copper core spark plugs.

You can't beat copper core autolites not only for the price but for their ability to help reduce knock ****** on a supercharged 3.8 L L67. There is a measurable difference. At least a 1.5 degree reduction going from the 605s which are 1 heat range colder. Forget those high dollar NGK, iridium , super duper electroblasters for $20 a plug.These old timers do the job. At least for my application they work just fine.
