Description of Autolite 303 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.

Powerful Spark for Smooth Ignition

These copper resistor spark plugs are a must-have for any automotive enthusiast. The improved conductivity ensures a strong and smooth ignition, leading to better engine performance and fuel efficiency. While the price may be slightly higher than other options, the long-lasting durability and consistent performance make it well worth the investment.

Pros
  • Reliable and durable for everyday use.
Cons
  • Requires more frequent maintenance than iridium or platinum spark plugs.

No deal, 4 packs in the photo is just one unit.

When it says "Pack of One" it means only 1 spark plug period. If you have a V-8, you need to order 8. The picture is not true, it is misleading. There is another seller (not the best) who sells the 4 packs shown in this picture for a fair price.

Pros
  • Spark plugs
Cons
  • I don't like anything about it, everything is fine

Correct spark plug for old engines. Used Champion

I liked not having to clean every four hours. Used on a 1954 Allis Chalmers WD45. I think it's a hotter fork. I have no more problems.

Pros
  • Resistor Reduces Radio Frequency Interference (RFI) and Electrode Erosion
Cons
  • Some Difficulties
