Review on ACDelco 748B Original Equipment Spark by Kevin Nicholas

Revainrating 3 out of 5

Disappointing Performance from Spark Plugs

I purchased these ignition parts for my automotive, and I'm pretty disappointed with their performance. While the product was easy to install, they provided a very poor spark, which ultimately hindered my car's acceleration and fuel efficiency..

Pros
  • Easy to install.
Cons
  • Poor performance detracted from overall functionality.
