Hello! I am 612 new owner, 2005, black. Fantastic car!!! Some questions: 1. How often the regulations of Ferrari need to change spark plugs? 2. Spark plugs are necessary for NGK Iridium 2316 DCPR9EIX? Right? 3. Whether I on F612 can establish original disks (Wheel rims) from Ferrari FF radius 20? 4. At a parking it is possible to leave the car on 1 gear? It isn't harmful to clutch? Thanks!
