[QUOTE="Cookie_Monster, post: 1869770, member: 64371"] [USER=47674]@Louisiana Barefoot[/USER] I've read the same, but when looking at the head design of the 6.2L Boss engine, designed specifically for the Raptor - it appears both plugs are equal. They both sit at around 45 deg. angle to the piston. In this picture the intake (top plug) is at the top and the exhaust (lower plug) is at the bottom. The plugs appear to be positioned just about equally between the intake and exhaust valves. With such huge valves, a centered single spark plug location is not really available. If anything, the bottom plug is a little more centered than the top. Not making excuses for Al Gore, but it's possible the ignition system had to be designed this way to produce an efficient 411hp NA motor (i.e. Power + MPG). Unburnt fuel is pretty much undesirable for everyone. Any Ford engineers in here know the story on the dual plugs? [ATTACH type="full" alt="Head_2 plugs.JPG"]390083[/ATTACH] [/QUOTE]
