What's The Most Legendary Four-Banger Of All Time?

Last winter, we asked for your opinions on theMost Legendary V8 Of All Freakin' Timeand theMost Legendary Inline Six... and then I totally spaced on what may be the most important Legendary Engine question of all!

No problem— this way you've all had 9 months to ponder the question. Personally, I'm torn between theOffenhauserand theFord Model T, but you don't have to go so far back in time to find plenty of four-cylinder engine legends. TheAlfa Romeo Twin Cam?TheToyota R?TheVolkswagen Air-Cooled?Some engine that isn't even in ourEngine Of The Day Overload?What doyousay?
