16 hp,ouch! 'guess we pay for those steep hatch angles.(still paying with the 2012 VW Beetle!)

Was the 1978 Accord a 'new' model body series or did they just do the engine mods? I've only owned the one Honda,and it seemed like they would introduce a new model on even years and let it run for 4-years.
That's pretty amazing about the significance of the intake tract!I wonder if California NOX standards forced them into the coolant-based system.
