Review on Bosch X5DC Copper Nickel Spark by Greg Usry

Revainrating 5 out of 5

Better Performance with Copper Nickel Spark

Based on my observations the ignition system of my car has been running smoothly since I installed this spark... The copper nickel composition provides better conductivity and durability compared to the standard copper spark plugs. However, the price is a bit higher compared to other options in the market..

Pros
  • Better performance, improved longevity
Cons
  • Pricier than other options on the market.
