Why spark plugs? I do not see how a spark plug can change much.
We use dual spark plugs in aircraft, but that is for redundancy. With one set running the power does go down some. But would just a spark plug add power? Spark is spark.
Some of the advertisements for spark plugs are funny to me. Have all these electrodes, it only takes one spark and only two electrodes to do it. Now iridium spark plugs last longer and foul less in aircraft, we call them fine wire and are about $100 each. Normal plugs are around $35 each.

I wanted to switch over to copper spark plugs. They're less likely to overheat. Overheating of the plugs can compromise the delivery of the spark to the engine.

ok, that makes sense, it is for a more robust spark plug.

Based on your desired mods, you could also use the bosch 63 lb injectors. They work great and are far cheaper. I had these injectors with similar mods and the duty cycle was fine (around 80%). I ended up getting id850s because i am adding more mods (heads/cam).

Ok thanks for the information. Just out if curiosity, what's the stock size injectors on the ZL1's?
