I do have a question about the plugs. I have never noticed a power gain in the beginning from better plugs. Is this just because my cars lag? Or is the advantage of better plugs, longer plug life?

The copper-core plugs are all most cars really need.

Many tests have proven that there is little to no gain in HP from expensive plugs . Platinum plugs simply extend the plug life but offer no better performance.

For a car that makes changing plugs a nightmare due to inaccessability or for the lazy, platinum plugs may be a good idea. Otherwise, stick with a stock plug for a low price. Gap it right, install it and be happy.
