Description of Autolite 4265-4PK Copper Resistor Spark Plug Set, Pack of 4

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. Fit type: Vehicle Specific.

Powerful Spark for Efficient Automotive Performance

This ignition part provided a noticeable improvement in my car's acceleration, fuel efficiency, and overall performance. It was easy to install and fit perfectly. The copper resistor ensures a reliable and long-lasting spark. However, it is pricier than some other options on the market.

Pros
  • Great conductivity and heat transfer due to copper construction.
Cons
  • Does not last as long as iridium or platinum spark plugs.

The Best of HD EVO in Parts

I've tried so many spark plugs on my 1999 Harley Fat Boy (Evo) and nothing beats how great they work. Good idle, excellent acceleration and coolness.

Pros
  • Spark Plugs and Wires
Cons
  • Updates Available

Wrong spark plugs sent to Spark Plugs and Wires

Enter the year and make of my Harley and did you receive the wrong parts. I received an email asking how the purchase went but when I told them I didn't get anything. I was expecting return instructions or something. Spring. On the same day I received the required spare part in Avtozona. If I get the wrong part, at least they make it quick and easy to return it. Savings on this product are not justified.

Pros
  • Replacement Parts
Cons
  • Fits
