I'm just curious...
What make/model/year of passenger car was first to use a panel type air filter?
How about the first use of a panel filter on a V8 (or V6) engine?
I doubt we'll find a definitive answer via Google... but it might be interesting to see how far back we remember seeing them.
Excellent trivia question; I remember replacing panel filters at my work with the introduction of the muti-port fuel injection that had an upper and lower intakes. I know that prior to that, we had throttle body fuel injection and it used the standard round air filter installed just like the carburated engines did.
It's a topic I was pondering while writing up an article about a Triumph Stag.
Stags were equipped with panel filters from day one, sometime in June of 1970.

Can anyone think of an earlier panel air filter application?
Yep,
1968 volvo 144 and mid 68 jag xj6
1975 MG Midget 1500.
That would be a neat addition to any MGB conversion engine bay- well if there was one that actually didn't look out of place.
