In that case, you must be talking about something other than the intake. Perhaps you mean the throttle or perhaps the piping.
Ya see, the intake is the item that sits under the blower and has eight little holes to allow the air to get inside the engine. It is physically impossible to bolt to a 6 cylinder. If you managed to cobble it together, the intake would have two passages open to the atmosphere. The engine would never run. It's not gonna happen.
