Comments about NGK Iridium IX Spark Plug:

These are what is recommended by Honda for the Civic for 2006-2011, however, I put them in my 2005 Civic Si, and they perform much better than the exact replacement ones for the K20A3. These are especially good if you are modding in a Civic Si, RSX, RSX Type-S, or anything else with a K20 engine. No, they don't provide a performance increase, but they will if you have mods that require them. But that isn't because of the spark plugs to begin with.
