I saw the little down-pointing 'trumpet' horn on the input to the resonator box-filter path, but what I was referring to, is the little air-duct that you can see on the extreme left end of the upper grill.
It's output is a few inches away from the trumpet horn intake.

I've seen these air inputs on other cars, feeding right into filter input.
I figured they wanted to drive cold air into the filter.

But, if we want warmer air going in, blocking that duct is a good idea.
Might keep a few insects out of the air filter too.
