Improved Engines with Copper Sparks!

Autolite's copper spark plugs offer a reliable and consistent spark for your automotive needs. They have improved the performance of my engine and I have noticed a significant increase in fuel efficiency. However, the copper material may not last as long as other options in the market.

Pros
  • Long-lasting performance due to high-quality copper core
Cons
  • May not be compatible with all vehicle models

Black Oxide Non-Nickel Plated

Black Oxide Non-Corrosive Nickel Plated Exactly the same spark plugs and heat ranges are available in a nickel plated finish for the same price.

Pros
  • Ignition Parts
Cons
  • Modern

Good quality at a low price

Don't forget to adjust the spark gap! First I install without adjusting the gap. Machine runs, but with poor acceleration (weak performance). Then I pull the old ones out of the bin, set the spark plug gap, then put them back in, wow! the car runs like a new engine. The Cooper spark plug actually has better conductivity than platinum; hence better performance. Only this cooper has a shorter lifespan. But at that price I wouldn't mind changing them every few years.

Pros
  • Spark plugs and cables
Cons
  • I will add later
