Description of Autolite 425 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.

Reliable Spark Plugs

After trying these spark plugs my car is running smoother than ever.The ignition system on my car was struggling to perform, but adding Autolite's copper resistor spark plugs made all the difference. My engine now starts with ease and the improved conductivity ensures that every cylinder fires properly. The only downside to these spark plugs is that they may not be suitable for high-performance vehicles or those with more demanding ignition systems..

Pros
  • Improved engine performance and easier starting
Cons
  • May not be suitable for high-performance vehicles

Subpar Spark, Disappointing Performance

This automotive ignition part did not deliver the necessary spark for my engine, resulting in poor performance. The copper material may have seemed like a pro, but it didn't make up for the lackluster results.However the price was affordable compared to other products..

Pros
  • Efficiently ignites fuel for smoother engine performance
Cons
  • Not as durable as more expensive spark plug options

Works but the packaging was incompatible.

The boxes looked like they had already been opened. The spark plugs looked new, but some were missing resistance tips. I had to pull them out of my old candles. They were inconsistent so I'm wondering if this was a comeback. So far they work great and the price is good.

Pros
  • Spare parts
Cons
  • -
