Most definitely. We have found that the best spark plugs to use are standard copper plugs such as Autolite and/or Iridium plugs. When possible or applicable, you may go to a one-step hotter plug. Double platinum plugs burn too cool. Standard plugs burn at a higher rate which this system needs. And, at the same time, you are saving money because the copper plugs are less expensive. In the newer vehicles Iridium spark plugs are also acceptable.
