Increased Power without Spending Much Part 2 : Copper Gapped Plugs

A cheap set of copper core spark plugs has a lower arc over voltage than the precious metal platinum or iridium types and hence fire a little more spark energy into the chamber.

Gapped down to 0.8mm for the most turbo application, they can eliminate small Top End Misfires and give a great, smooth power result. The only downside is that they will need replacing every 10,000 km or so. The upside is they are very cheap. Do have a try on it yeah.


  1. I am using NGK Platinum plug........still good after 50k km. It is suppose to last at least 100K km.

  2. Yea, it normally last you around (100-150)k km
