Review on Autolite 2956 4PK Copper Non Resistor Spark by Mark Nicholas

This spark plug is a must-have for anyone who wants to improve their automotive ignition performance. Through trial and error, I found that the non-resistor copper design generates a much stronger spark, resulting in better overall engine performance. The spark plugs are easy to install and come in a convenient 4-pack.Automotive enthusiasts will appreciate the improvement in their vehicle`s acceleration and fuel efficiency. The ONLY downside is that they may not be the most durable option on the market..
