Description of Autolite 5663 4PK Copper Resistor Spark

Copper-glass seal bonds insulator, terminal post, and center electrode together to provide a tight seal that is 100 percent leak-proof. Cold-formed steel shell and precision rolled threads, with one-piece terminal post to add strength. Multi-rib insulator reduces danger of "flash-over". Resistor reduces radio frequency interference (RFI) and electrode erosion. Full copper core electrode provides better performance in all conditions.

2013 Abarth for Ignition Parts

Great spark plugs. I use them in my 2013 Abarth. I like them better than the stocks. They have 1/3 to 1/2 the lifetime of ngk. The motor feels better with copper. The price has doubled in recent months.

Pros
  • Ignition Parts
Cons
  • Some issues
