Description of Autolite 45 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 for My Ride!

As an automotive enthusiast, I was in search of reliable ignition parts for my ride. After testing various products, I determined that Autolite 45 4PK Copper Resistor Spark undoubtedly stood out. The spark plugs delivered reliable performance, making my engine start-up a dream. The copper construction and resistor feature helped eliminate engine misfires and improved fuel efficiency. The only downside is that they require slightly more maintenance than other spark plugs, but the performance…

Pros
  • Provides reliable ignition and extended electrode life thanks to the copper core and resistor.
Cons
  • Not ideal for high performance or modified engines because the spark plugs have a lower heat range than other options on the market.

Autolite Spark Plugs

I like Autolite spark plugs because they perform better than others in our cars. Just remember to coat the threads with a non-stick coating, even with cast iron heads. Apply anti-seize to the spark plug threads, especially aluminum heads.

Pros
  • Copper core electrode for best performance in all conditions
Cons
  • Damaged

Autolite is a great product.

I have used this brand on my trucks and Fords for many years. This order was for my 1965 Ford F100 with big block engine. These spark plugs are a perfect match for the 352 Thunderbird Interceptor engine currently on the truck.

Pros
  • Multi-ribbed insulator reduces risk of rollover
Cons
  • Makes me nervous
